You should install a new group gasket about once a year. It is easy to install and you can do it from home. First, you will need to get a new gasket. Please call us to order. The gasket is a large, black circular rubber piece in the group head. This is where your machine makes a seal for pressure brewing. To replace it, follow these instructions:

You will need a broad, flat-head screwdriver.
1. Unplug the machine and let it cool down completely (this is VERY important).
2. Remove the water reservoir and the drip tray grid and drip pan.
3. Locate the shower screen. It is right above where the portafilter normally sits. It looks like a circular metal screen.
4. The screen has a smooth cuff around the edge. It is held on by pressure (no screws or bolts). Just above the screen, along the smooth cuff, is a small indent that goes all the way around. This is where you will pry down using the screwdriver. Place the blade of the flat head screwdriver at the indent and pry down carefully. DO NOT pry down on one side only, as this could warp or bend the piece. It should be pried off slowly from alternating sides. Like a paint can.
5. The group gasket should come off along with the screen and cuff. If it does not, simply pull it straight down until it comes off.
6. Inspect and clean the group head. Make sure the shower screen is clean as well. You can soak it in descaler if needed. DO NOT push a pin through the screen to clear out any clogs. It will increase the diameter of the holes promoting future clogs.
7. Stretch the new gasket over the screen. The side that is beveled should face up into the machine. The completely flat side will face down to create a seal with your portafilter.
8. Push the shower screen back into place with your hand. Make sure it is in securely and completely before inserting your portafilter.
9. Replace the water reservoir, drip tray and drip grid.
10. Turn on the machine and you are ready to brew again.
If you need parts or further assistance, please contact us at 1-888-411-5282

There are several possible causes of this problem. Please follow the instructions below to solve it.

Solution 1

This problem can occur if the metal filter basket in the portafilter is damaged around the edges, or if coffee has built-up on the edges. Ensure that your filter basket is clean around the edges, and if it is damaged, replacements are available by calling us at the number below.

Solution 2

The most common solution to this problem is to replace the group head gasket. You should install a new about once a year. It is easy to install and you can do it from home. First, you will need to purchase a new gasket. Please call us to order. The gasket is a large, black circular rubber piece located in the group head.The group gasket surrounds the shower screen.

There are several possible causes of this problem. Please follow the instructions below to solve it.

Solution 1

The most common solution to this problem is to backflush regularly. You should backflush the machine once a week with water, and every other week with backflush-cleaning powder. We recommend Cafiza by Urnex. You only need to use about 1 teaspoon each time. To backflush, follow these steps:

1. Turn the machine on and let it heat to normal brewing temperature.
2. Remove the normal basket from the portafilter and insert the backflush disk. The backflushing disk is either rubber or stainless steel. It will have no holes in it.
3. If backflushing with just water, insert the portafilter into the machine normally as if brewing.
4. If you are going to backflush using the cleaning powder, simply sprinkle about a teaspoon onto the backflush disk, and then insert the portafilter into the machine normally.
5. Turn on the brewing mechanism. (some machines have a switch, some have a lever, and some a free flow button)
6. Listen to the pump. It will begin normally and then change pitch. After the pump changes pitch, count to three.
7. Now, stop the flow of water by stopping the brewing mechanism.
8. A gush of water is now expelled into your drip tray. Repeat steps 2-6 again at least 2 more times. You can repeat it until you feel like the brew head is clean. Make sure if you are using backflush cleaner, to remove the portafilter after several cycles and make sure all of the powder is dissolved and no longer visible.
9. Remove the portafilter and take out the backflush disk. Replace the regular filter basket and you are ready to brew again.

Solution 2

If the first solution does not work, your shower screen may be clogged. This can happen through regular use. Some common causes are not backflushing on a regular basis, or using a very fine grind. Follow these steps to remove the shower screen:

1. Make sure your machine is cold and unplugged.
2. You will need a thin flat head screw driver.
3. Now locate the shower screen. It is above the spot where you insert the portafilter for brewing. It is a metal screen that has many holes in it. It is held on by a pressure cuff. The cuff surrounds the screen and is silver in color.
4. You will need to pry off the cuff in order to access the shower screen. DO NOT stick the screw driver blade between the screen and pressure cuff. This will ruin your shower screen and you will need to purchase a new one.
5. The top of the pressure cuff is located right where the group gasket meets it. The group gasket is a large black rubber ring located on the outer perimeter of the group head.
6. Place the flat blade of the screw driver in the area where the group gasket and pressure cuff meet. Pry slightly downwards. DO NOT pry the pressure cuff down in one location. It will bend. You need to remove it as you would the lid of a paint can.
7. Pry all the way around until the pressure cuff can be easily removed. You do not have to use a lot of force.
8. Remove the shower screen and hold it up to a light. You should be able to see through most of the holes. If not, soak it in some dissolved backflush cleaner, such as Cafiza by Urnex. DO NOT use a pin to clean out any clogs. This will expand the openings and cause future clogs in the group head.
9. Clean the group head using a brush. Make sure it is mostly clean. You can dip the brush in the dissolved cleaner to aid in the cleaning.
10. Replace the shower screen by simply pushing it back into its place.
11. Backflush your machine, making sure to thoroughly rinse any cleaner you have used.
12. Your shower screen is now clean. Do this at least once every 6-8 weeks to keep your machine working at its best.

Solution 3

If the first 2 solutions did not work, you may have a major clog or a pump issue. Please call us to set up a repair.

There are several possible causes of this problem. Please follow the instructions below to solve it.

Solution 1: Adjust the pressure stat

The most common solution to this problem is to adjust your pressure stat. The pressure stat controls the pressure and temperature in your boiler. It is a black or black and yellow plastic piece that is very close to your boiler. To adjust it, follow these instructions:

Tools required:

• Phillips head screwdriver
• 3mm Allen wrench
• 17 mm socket and ratchet
• WD-40

a. For the all black pressure stat: There is an adjustment wheel about half way down the pressure stat. The wheel has ridges. Turning it counterclockwise will decrease the pressure and clockwise will increase pressure/temperature.
b. For the black and yellow pressure stat: There is a red cap in the middle of the top of the pressure stat. Remove this red cap by prying it off. There is a small yellow spot of paint holding the cap on. It is ok to break this seal. Under the cap you will find a very small Phillips head screw. Turning the screw clockwise will decrease pressure and counterclockwise will increase pressure/temperature.

• Phillips head screwdriver
• 3mm Allen wrench
• 17 mm socket and ratchet
• WD-40

Your machine may be experiencing a bit of vapor lock, which can happen occasionally. Try to keep the water reservoir to full capacity if possible, but if you run into this issue again, you can remedy it by forcing water through the tube manually. Follow these steps:

1. Unplug the machine and allow it to cool completely. Make sure the reservoir is full or the machine will not function.
2. First you need to get a turkey baster or something that can inject water with some pressure. If you do not have anything suitable please call us to order a priming pump.
3. Look into the reservoir and find the soft tubes. There is usually 1 or 2. You will need to locate the inlet tube. It is usually the longer tube with a V-shaped cut or angled cut at the end. This is the tube you are going to inject water into. NOTE: if your machine has a water softener on it, remove this while priming.
4. Fill the turkey baster or priming pump with water.
5. Plug in your machine and turn it on.
6. Now the pump will activate. Quickly make a tight seal with the priming pump/turkey baster and the inlet tube and force water into the tube.
7. As soon as you have injected the water, turn the pump off by turning off the brewing button (we recommend doing this step 2-3 times before going on to the next step).
8. Once you see water being pulled through the machine, replace the tube into a FULL water reservoir and let the water run out of the steam wand for 1 minute or until you no longer see sputtering. Your machine is now re-primed and ready to use again.

There are several possible causes of this problem. Please follow the instructions below to solve it.

Solution 1

The most common solution to this problem is to clean out the Vacuum Relief Valve (VRV). It is a small valve on top of the boiler that prevents vapor lock. As the machine heats up, it builds pressure. The pressure forces up a small plunger, sealing the VRV and the boiler will be able to begin building pressure. Follow these steps to clean it out:

Tools required:

• Phillips head screwdriver
• 3mm Allen wrench
• 17 mm socket and ratchet
• WD-40

There are several possible causes of this problem. Please follow the instructions below to solve it.

Solution 1

The most common solution to this problem is to reset the high limit switch. This safety switch is designed to cut off power if the boiler gets too hot. It can also trip if you have some sort of electrical issue such as a power surge or an electrical short in the machine. To reset the high limit switch, follow these instructions:

Tools required:

• Phillips-head screwdriver
• 3mm Allen wrench
• Needle-nose pliers

The water softener helps keep the amount of scale build up under control. It is attached to the end of the soft rubber inlet tube in your water tank. It looks like it is full of little crystal grains. The water softener should be cleaned and recharged about once every 1-2 months, or more frequently if you have a higher mineral content in your water. To charge it for the first time, or to recharge it, follow these simple steps:

The machine should be off and cold before following these steps.

1. Prepare a solution of 3 teaspoons of fine salt and 8 oz of water. Mix well.
2. Remove the water softener from the rubber tube by pulling the pointy end off of the soft rubber tube. Make sure you do not pull the end of the water softener off.
3. Pour the solution through the big end of the filter. It will flow freely out of the bottom pointy end.
4. Let is sit for about 5 minutes, then run tap water through it to rinse it. When the water coming out of the softener is no longer salty, the water softener is fully charged/recharged and ready for use.
5. Put the softener back on the tube by simply pushing the pointed end back into the soft inlet tube.
6. Put them both back into a full water tank. It may float up, and this is normal as long as the end that allows water to enter the machine is submerged. You do not want the machine to accidentally suck in some air, causing the pump to lose its prime.

The machine is now ready to be turned on and used again.

Expobar machines are not designed as pod machines, but it is possible to brew pods with them by using the Gaggia pod filter basket. Because of the high quality brewing components, Expobar machines are designed to make an excellent shot of espresso. This is best done by using your own freshly ground coffee rather than pods. Pods do offer added convenience when brewing, but with a highly capable machine like the Brewtus II, you will always get the best results if you can perfect the grind and tamp yourself.

Gaggia Gaggia Pod/Single Filter Basket

Both of these models offer outstanding durability, and are designed with many of the same high quality brewing components. Upgrades to the Expobar Office Lever include an authentic E61 brew group, a manually operated 3-way solenoid valve, 100% stainless steel body, redesigned knobs, and a redesigned steam arm. The commercial E61 brew group is known throughout the industry to be one of the best due to its thermal siphon design, which circulates hot water from the boiler through the group to maintain ideal brewing temperatures. Its temperature stability is as good as it gets.

However, because of the E61 brew group, the Office lever lacks the programmable functions that are available on the Office Control. The Office Control has four programmable brewing buttons and the 3-way solenoid valve activates automatically at the end of the brewing cycle. While both machines have a stainless steel exterior, the Office Control has a steel frame while the Office Lever is made entirely from stainless steel.

If you are not able to get water out of the machine at all, your boiler may be having trouble priming. This is not uncommon - you will simply need to prime the machine manually. Please call us at 888-411-5282 so that we can give you directions on how to do so.

There are a few things that will help get your espresso hot. The first, which you mentioned, is letting the machine heat up a little longer before you use it. Make sure that the temperature ready light comes on before you try to use the machine. After the machine says its up to temperature, you’ll also want to run a "blank shot". This is simply activating the brew function while the empty portafilter is in place to allow hot water to come through the brew group and portafilter. In addition, you should preheat the cup you’ll be brewing into with hot water. Cold brew groups, portafilters, and cups will absorb the heat from your espresso, making it colder and reducing the amount of crema you get. Preheating all of these components prevents that from happening and helps you to get the perfect shot.

Adjusting the pressurestat is very easy, and we can provide you with instructions on how to do it if you call us at 888-411-5282. If that doesn’t seem to do the trick, we can send you a replacement along with instructions - another easy process.

The temperature of the water in your cup is fairly normal - although the machine brews at a higher temperature (around 200F), after its exposure to air and absorption of some of the heat from your cup, 180 is right on target, so I don’t think it’s a temperature issue. It sounds like you may simply need to give your steam tip a good cleaning. Just add a spoonfull of Cafiza (what you use to backflush) to a cup of hot water and let the steam tip soak for a while. As some preventative maintenance, after steaming your milk you should blow some additional steam out of the wand to ensure nothing is stuck in the wand. If you’ve tried this and are still experiencing problems, give us a call at 888-411-5282 so that we can more thoroughly diagnose the problem.

We can email you a copy of the directions if you give us a call at 888-411-5282.

There are several possible causes of this problem. Please follow the instructions below to solve it.Solution 1

Sometimes, a slightly finer grind can cause this. Try to keep your tamping pressure consistent and try a slightly coarser grind. The volume of coffee grounds can also cause a fluctuation in the amount of coffee dispensed, so make sure you are always using the same amount.

Solution 2
Another solution is to reprogram the brewing buttons. To do this, follow these instructions:

1) Press and hold the free flow button (the button with the star icon) for 5-8 seconds. All the lights above the programmed buttons will then go solid.
2) Place a measuring cup under the coffee spouts.
3) Choose a button you would like to reprogram and push it. The light above this button will then go dark.
4) Allow the desired amount to be dispensed.
5) To stop the flow, press the same button again. The light above the button will remain dark. This is normal.
6) You do not have to reprogram all the buttons at once. You can do 1 or all if you wish.
7) To exit the programming mode. Press and hold the star or free flow button again for 5-8 seconds and release.

Solution 3
Another possible solution is that your machine needs a good cleaning and should be backflushed with backflush-cleaning powder. We recommend Cafiza by Urnex. Your machine should be backflushed once a week with water and every other week with backflushing powder. You only need to use about 1 teaspoon each time. To backflush, follow these steps:

1. Turn the machine on and let it heat to normal brewing temperature.
2. Remove the normal basket from the portafilter and insert the backflush disk. The backflushing disk is either rubber or stainless steel. It will have no holes in it.
3. If backflushing with just water, insert the portafilter into the machine normally if brewing.
4. If you are going to backflush using the cleaning powder, simply sprinkle about a teaspoon onto the backflush disk, and then insert the portafilter into the machine normally.
5. Turn on the brewing mechanism. (some machines have a switch, some have a lever, and some a free flow button)
6. Listen to the pump. It will begin normally and then change pitch. After the pump changes pitch, count to three.
7. Now, stop the flow of water by stopping the brewing mechanism.
8. A gush of water is now expelled into your drip tray. Repeat steps 2-6 again at least 2 more times. You can repeat it until you feel like the brew head is clean. Make sure if you are using backflush cleaner, to remove the portafilter after several cycles and make sure all of the powder is dissolved and no longer visible.
9. Remove the portafilter and take out the backflush disk. Replace the regular filter basket and you are ready to brew again.

Solution 4

If all of the above solutions do no work, you may have an issue with the control board in your machine. Please call us to set up a repair or order this piece. It is very easy to install and can be done from home. If your machine is still under warranty, it must be sent in to have this piece inspected and a new one installed.

To remove the shower screen on the Expobar, you’ll need to use a flat head screwdriver. Insert the flat side of the screwdriver on the right side of the group head, between the shower screen and brew group, and apply gentle pressure to start prying it out. Then do the same thing on the left side of the group head to prevent bending the screen. You can request a set of detailed instructions on cleaning the shower screen a brew group by calling us at 888-411-5282.

If your machine is tripping your GFI switch, you may need to send it in for repair. Please call us at 888-411-5282 so that we can thoroughly diagnose the problem and provide you with the most appropriate solution.

It sounds like you simply need to replace the brew group gasket, which is generally necessary every year or so. Please contact us at 888-411-5282 so we can send you this part and instructions on how to replace it.

If you’ll be away from the machine for a week, I would recommend turning it off and unplugging it for that time. It’s also a pretty good idea to empty the water reservoir beforehand, as you wouldn’t want to use that week-old water when you come back anyway. In addition, when you do return you’ll want to run an entire reservoir’s worth of fresh water through the machine to get out the water that’s been sitting the boiler while you’re gone. After that you should be good to go.

You don’t have to remove the filter basket every day for cleaning, but I would recommend rinsing and wiping the filter basket out every time you’ve knocked out your spent grounds. However, the filter basket should be removed every month or so for deeper cleaning. You can usually remove them with a fingernail, but a butterknife or flat screwdriver will do if it’s really snug - just be careful not to bend the basket with your force. Then simply add a teaspoon of Cafiza (what you use to backflush your machine) to a cup of hot water and let the filter baskets soak for 10 or 15 minutes. Also, hold the filter basket up to the light to see if any of the holes are clogged. If you do notice this, you can clean the holes out with a toothpick and then soak the baskets as recommended.

Espresso should be brewed in the 200ºF range. Our tests have shown that the Office Control brews consistently at 198ºF, so it’s right on the mark. Please note that this is the temperature of water as it exits the group head and not in cup. Due to being exposed to the air and the heat absorption that can occur from the cup itself, the in-cup temperature tends to be a bit lower. Information like brewing temperature can be found for any of the espresso machines we carry by following the link below to our Compare-O-Matic.

It sounds like you simply need to reset your high limit switch. Please contact us at 888-411-5282 so that we can send you instructions for this procedure.

The Expobar’s group head and portafilter have a 58mm diameter, which is the standard commerical size. This means it would use a 58mm tamper as well. Information like this can be found for any of the espresso machines we carry by following the link below to our Compare-O-Matic.

Expobar does not currently manufacture a single spout portafilter. However, even though the espresso is coming out of both spouts, you can catch both streams in a single cup if it is positioned in the center.

Although a bit of tightness is normal when the machine is new (you will notice that the group loosens a bit over time), you should be able to get it near to the 6 o’clock position without too much difficulty. It sounds like you may be adding too much coffee to the portafilter, which will make it difficult for you to lock the portafilter into place.

Although there are quite a few similarities between these machines, there are a few significant differences that should help you make a decision.

The first of these is each machine’s portafilter. The Bodum Granos has a 51mm pressurized style portafilter, whereas the Expobar has a 58mm commerical style portafilter. Commercial style portafilters give the user the most control over the final product, but that also means that you need to have complete control over the grind fineness and the tamp pressure you use to brew. On the other hand, pressurized style portafilters reduce the amount of control you need to have over these variables, making it easier to brew with preground coffees. Pressurized portafilters virtually eliminate the "learning curve" that’s associated with commercial style portafilters, but also require you to give up some of the control over the brewing process and in effect, over the final product as well.

The other main difference between these machines is their respective boilers. The Office Control has a 1.7 liter heat exchanger boiler, compared to the Granos’ 3 oz standard boiler. Heat exchanger boilers not only allow you to switch from brewing to steaming without waiting for the machine to change temperature, but their large size also provides better steam pressure for a longer amount of time and basically eliminates down-time between shots. With the smaller boiler in the Granos, you will need to wait for the machine to switch temperatures when going from brewing to steaming (which can take around 30 to 45 seconds) and will experience some down-time between brewing as the water in the boiler refills and reheats.

So your choice will basically come down to 2 things: how much time you’re willing to invest in learning the ins and outs of brewing with your machine and how frequently you’ll need the ability to make several drinks without any downtime. Once you’ve thought about those factors, you should easily come to a decision.

Actually, the Office Control’s reservoir is a little bit smaller. The Control has a 72oz reservoir, whereas the Brewtus’ is 98 oz. Information like this can be found for any of the machines we carry by following the link below to our Compare-O-Matic.

For the best results, we recommend using a 58mm tamper. You can take a look at our 58mm Reg Barber tampers by following the links below.

It sounds like you need to adjust your pressure stat and/or clean your vacuum relief valve. For detailed instructions on these procedures, please contact us directly at 888-411-5282.

Yes, you will have to tip the drip tray a bit to remove it from the front of the machine. Because of this, you should empty it before it gets completely full.

Generally, we don’t recommend using distilled or reverse osmosis water for a few reasons, the largest of which is because the internal water sensor has a hard time reading it. Since both of these types of water contain no minerals, we’ve also found that they generally produce a flat tasting espresso. We recommend using filtered bottle or tap water, but if you do use distilled or RO water, you will need to add about 8 oz of tap water to it to increase the particle content for the water sensor to recognize it.

It sounds like you may simply need to adjust your pressure stat. Instructions are below. If you have any further questions, please contact us at 888-411-5282.

Is your Expobar running a little too hot? Not hot enough? Your pressure stat may need to be adjusted.

 Please read the entire instructions before you start.

Tools Required: 3 mm Allen wrench

Phillips head screw driver

Small flat head screwdriver

1.Always unplug the machine.

2.Remove and empty the reservoir.

3.Taking the top off. Taking the top piece of the Expobar Office Pulser/Control begins by unscrewing the 2 chrome Phillips head screws on top of the machine in the front left/right corners. The fasteners are chrome Phillips head screw or chrome 3 mm Allen bolts. They may also be a combination of both. The other two fasteners, located on the top panel near the back panel are chrome 3mm Allen bolts. They are covered with small, round, black plastic caps.

4.Lift off the top panel. On some machines, the top panel and reservoir assembly are connected. If they are, then the whole structure will lift right out of the machine. If not, then you will have to remove the large, black, step-shaped reservoir plate. After the plastic zip tie at the front is cut, it will lift straight out.

5.Identifying the pressure stat. The Expobar pressure stat is located, if facing the front of the machine, in front of the boiler, just beneath the large copper tubes that go in/out the group head. The stat is round, about 1 in across. The body is black, with a yellow face. In the center, under a small red cap is the adjustment screw. It is a small brass flathead screw slightly recessed into the yellow face of the pressure stat.

6.Clockwise turns the pressure down. Counterclockwise turns the pressure up. When you make adjustments use ¼ turns or less at a time.

7.Re-assemble in reverse order.

Before programming your brewing buttons, there are a couple of things to keep in mind. First, you want to make sure you’ve brewed a shot with the manual button to ensure you’re meeting the golden rule. Secondly, make sure you’re actually brewing a shot when you program the button to ensure that the programmed volume will be accurate.

To access the programming mode, press and hold the manual brewing button (*) for about 7 seconds, or until all of the LED’s on the keypad light up. At this moment, press the button you would like to program. (Please note that if you do not press a key selection within 5 seconds, the keypad will come out of program mode and you will have to enter into program mode again.) When the quanitity in your cup reaches the desired level, press the same button again. The LED on this selection will then turn off to show that the programming has been successful.

Regular maintenance of this machine requires backflushing every day with water and weekly with a cleaner like Urnex Cafiza. Cafiza is available through us and can be purchased online by following the link below or over the phone by calling us at 888-411-5282.

This doesn’t sound like anything is wrong with the machine - it’s actually working very well. The pump is kicking on because the water in the boiler has started to dissipate over the hours that the machine hasn’t been used. The pump is simply coming on to bring new water into the boiler and prevent it from burning out. This is actually preventing the machine from having a future problem and shouldn’t worry you at all.

One of the main reasons for an uneven pour like you’re describing is if your tamping isn’t level. If you simply apply more pressure on one side than the other, water will find the path of least resistance through the less-tamped side. However, if you’re pretty sure that tamping isn’t the issue, it could be that your machine is sitting on a surface that isn’t level. Try propping up the side of the machine that more espresso seems to come out of. As long as your tamping is even, this should remedy your problem.

They key to consistent crema is consistent temperature. There are two things that you can do to acheive this. The first is to run a "blank shot" through the machine prior to brewing. This involves attaching the empty portafilter to the machine and pressing the brewing button to allow hot water to make its way through the portafilter and group head, ensuring that these components are up to brewing temperature. In addition, you should make sure to preheat your cups using either water from the brew group or hot water wand. The reason for this is because a cold portafilter or cup will absorb heat from your espresso and alter the flavor as well as the amount of crema you get. Feel free to contact us again with any further questions.

There really isn’t any specific shutdown procedure. You can simply turn the machine off - venting the pressure from the boiler isn’t necessary.

Your thinking is correct - this is something that can be adjusted easily to fix the problem. First, remove the reservoir, and then remove the metal plate below it. Simply put a slight downward bend in the center of the metal plate, so that when you replace it the center touches the sensor before the sides reach that level. Replace the reservoir, and you should be all set. If you continue to have problems, feel free to contact us directly at 888-411-5282 for further assistance.

Thanks to its heat exchanger boiler, the Office Control is able to brew and steam at the same time.

It is possible to make Cafe Crema with this machine. Cafe Crema is made by pulling 6 -8 oz of water through grounds that are more coarse than your standard espresso grounds. For either Cafe Crema or regular espresso, it is imperative that your grounds be consistent (you shouldn’t get both large chunks and dust particles at the same grind setting), so I would recommend investing in a capable grinder for use with this machine. You may want to take a look at the Rancilio Rocky grinders to start. I have linked to these and a few other grinders below so that you can learn more about them.

Unforutnately, we do not carry a 220v version of this machine, or any other machines on our site.

You should not decalcify machines that have heat exchanger boilers (like the Expobar). Due to the design of the boiler, it would be nearly impossible to remove all of the decalcifying solution short of removing the boiler from the machine and taking it apart yourself - this is not recommended by Whole Latte Love or the manufacturer. The best thing you can do to keep your machine clean is to backflush it. This is a simple process that removes coffee oils and residues from the brew group through the solenoid valve. I have provided a link below to our article on backflushing so that you can learn more. In addition, I have linked to Urnex Cafiza and Backflush discs, both of which are necessary for backflushing.

According to our in-house testing, the Expobar machines were able to froth up to 12 oz of milk in around a minute and a half. With the heat exchanger boiler, there is also no down time between brewing and steaming, so you can make drink after drink without stopping. You can view information like this for any of our machines by following the link below to our Compare-O-Matic.

The Rancilio water softener should work well with your Expobar machine. Because it isn’t specifically made for the Expobar, it may take a little finagling to make it sit properly in the reservoir, but it will still work very well. You can purchase this item by following the link below.

Unfortunately, there still is not a plumb kit available for the Expobar machines. We are still working on creating one and it will be up on our site as soon as possible. Please keep checking back for updates.

The Expobar is capable of producing about 10 cups an hour, but using it at this volume for an extended period of time may cause the machine to wear down quicker. If you’re looking for something that can produce more than that, I would recommend taking a look at the Rancilio S24 - it will be much more suited for that type of volume. I have provided a link below to the product page for the S24 if you’d like to learn more about it.

The ready light for the Expobar will come on after the machine has been heating for 7 minutes, but it is recommended that you let it heat up for a full 15 to make sure all of the components are thoroughly heated. It also helps to run a blank shot (pulling water through the brew group and portafilter with no coffee added) to makesure that the portafilter is sufficiently heated as well.

This machine, like all other espresso machines, will brew at between 8 and 9 bars of pressure. The pump is capable of producing up to 15 bars, but this has no effect on the brewing pressure - it will always brew at 8 - 9 bars.

You can use the Rancilio 3-hole steam tip, however, you will want to make sure that you’re not using the adapter that comes with it because it will not fit the Expobar. You can purchase the Rancilio 3-hole steam tip by following the link below, or by calling us at 888-411-5282.

The Expobar machines are not NSF approved. If you are looking to put this machine in a commercial environment, I would investigate your local health regulations before purchasing, as they do vary from state to state.

The two tubes do not need to be tied together, this simply keeps the tubes from floating.  The tube with the white particle filter at the end is the pump intake line that pulls water into the system.  The second line is there as a return line.  This machine has a pressure regulator that diverts excess pressure back into the reservoir.  The intake tube should always be immersed as far into the water as possible.  The return line does not have to be immersed in the water at all, although it prevents any excess water from exiting the machine. 

Whole Latte Love carries all Expobar parts.  Please give us a call at 888-411-5282 to place your order for the steam tip and we’ll have you making perfect froth again in no time.

These and all Expobar parts are available through us.  Just call us at 1-888-411-5282 and speak with one of our sales representatives to place an order.

The Office Control can make any espresso-based drink like a latte, cappuccino, americano, cafe crema, macchiato and more. All of these drinks start with espresso and then you can steam or froth milk using the Control’s steam wand or add hot water depending on the drink you’re making. To learn more about the drinks you can make with your espresso machines and the recipes for them, follow the link below to our article on the subject.

You should backflush your machine every day using just water, but about once a week using a cleaning agent like Urnex Cafiza. To purchase or learn more about Urnex Cafiza, follow the link below.

The shower screen is held into place by the brew group gasket.  It is normal if they come out occasionally, however if it continues to happen there may be an issue with the shower screen or gasket not fitting in the machine properly.  If the problem persists please contact us at 1-888-411-5282.

The group gasket works as a seal keeping shower screen in its place. Sometimes when you are brewing or backflushing could happen they come off. Take advantage of this situation and clean them using a toothbrush (for example) and small pin to clean the holes. If the rubber gasket and the screen come out frequently they need to be replaced.

This is a clear indication that the machine is in need of cleaning.  Your Expobar should be cleaned aproximately twice a week.  The cleaning process is called backflushing and is very simple.  I have included links to an article explaining the process and also the products recommended for backflushing below.

The Salvatore machine is considered a more commercial machine than the Expobar.  The can brew up to 100 cups a day whereas the Expobar can brew  up to 75 cups per day and. Your should check your local health codes to see what approvals are needed in your area for using a machine commercially; of these two, only the Salvatore is NSF approved.  Both machines can brew and froth at the same time which will make your process very fast. Brewing times will be the same with both machines, but the Salvatore also has a larger boiler which will give you better steam pressure and ultimately allow you to froth faster. Both machines are very well built and will withstand daily use in a commercial enviroment.  Your choice should probably be determined by the customer volume you are anticipating and by making sure you’re adhering to your local health codes. Also, please be advised that warranties are void on machines shipped outside of the US.

Very basically, the Golden Rule states that using the correct amount of coffee (based on a single or double shot) should produce a shot of espresso in 20 to 25 seconds. Changing the grind setting or the amount of tamp pressure you are using will change how quickly the shot is produced. Follow the links below to find more in depth discussions of the Golden Rule.

What you’re noticing is completely normal - it’s just the solenoid valve doing its job. Once brewing is complete, the solenoid removes excess water and pressure from the brew group and deposits it in the drip tray to leave you with a drier puck that will easily knock out of the portafilter.

It isn’t recommended to leave the machine on if it will be going more than an hour or so without being used. Leaving it on for extended periods of time without use could cause problems down the road. I might recommend getting a lamp timer for your outlet - then you could set it to turn on at a specific time in the morning so it would be heated for you when you’re ready to brew.

Although it can’t hurt to try your current grinder before purchasing another one, you will probably find that an upgrade is necessary. The Antigua tends to have trouble grinding at the fineness that will produce the best results for your Expobar. As an alternative, I would recommend taking a look at the Gaggia MDF or Rancilio Rocky. Both of these grinders will work very well with the Expobar. You can learn more about these machines by following the links below.

To prepare the Expobar Office for storage, you need to completely drain the boiler. For complete directions on this procedure, please contact us directly at 888-411-5282.

Some portafilters are interchangeable between different manufacturers. If the portafilter fits the Silvia it will fit the Expobar as well.

Yes, for the brew head to achieve brew temperature. The red led indicator will tell you when everthing is up to temperature.  At that point you will want to run a blank shot through the machine by pressing one of the brew buttons without any coffee in the portafilter. Now you have preheated the components and are ready to brew. 

I like to use a 58mm or 57mm tamper with that machine. It doesn’t makes much difference if you use a flat or a rounded base. As far as the quality of the brew is concerned it does not matter what material the base is. The important part will be how much pressure you put on the tamper. Our favorite tampers are the Reg Barber tamper with the Rosewood handle the Stainless Steel flat base. They look great, feel good in your hand and are durable. They are the most expensive tampers we sell so I also recommend you check out our Tamper page for additional choices.

Steam coming through the brew group is perfectly normal on any Prosumer/Heat Exchanger machine. With any of these heat exchanger machines I recommend first filling the filter basket with coffee and them tamping it. Then turn on the pump without the portafilter in place run. Let it run with the steam and water coming through just until the steam stops. Then turn off the pump, install the portafilter and brew right away. This will make sure that the brew temperature is not to hot. It is normal for it to take more than five second to purge the steam out. You can use this steam and water to preheat your cup.

We do have a nice tip that we call an S24 three hole steam tip that does pretty well. If you would like one give us a call. I recommend that you read the frothing technique section in the supplemental instructions that we wrote up and included with your machine. By following these techniques you should be able to use the tip that came with the machine. Give us a call if we can help.

Sometimes right out the box the line that has the water filter will pop up. If this happens not enough of the water line is in the reservoir. Pull out some of the slack form inside the machine and push it into the reservoir. This should take care of it.
