Expobar Office Control Espresso Machine
|1x Blind Filter Basket - Backflush Disc||$8.53|
|1x Rattleware Stainless Steel Latte Art Pitcher||$12.49|
OverviewBack to Top
The Expobar Office Control commercial espresso machine is truly in a league of its own. It is a fully automatic espresso machine that has four programmable buttons for dispensing any amount of water through your coffee with the push of a button. The commercial style boiler is made of copper and has all the controls that are found on the larger commercial machines. It can simultaneously brew and steam, allowing for extensive flexibility. This machine is sensational for those who love to entertain, or even just for the executive who does not want to visit the drip coffee machine down the hall. It has both a steam wand and hot water dispensing wand that are mounted on ball joints so that they can swing in any direction. Its size makes it convenient for those who don’t want to give up a large amount of counter space. It is 15.5” tall, 9.5” wide and 16.5” deep. The group head is comparable to the renowned E61 group head with pre-infusion and thermal siphon for maximum temperature stability and aroma extraction. The stainless steel housing is as beautiful as it is durable. The accessories include a chrome plated brass portafilter, tamper, single shot filter basket, double shot filter basket and a 7 gram coffee scoop.

Features & Benefits: Coffee
Commercial Size and Style Portafilter Handle
Made of chrome-plated brass for excellent heat stability which is essential for producing top quality espresso.
Commercial Brewing Group
The brew group is the large piece of chrome-plated brass that the portafilter inserts into. The Expobar brew group has a thermal siphon that is constantly circulating water through it to keep it hot at all times. It is never necessary to run a blank shot to preheat it.
Commercial Design Heat Exchanger Boiler System
The all copper boiler has a capacity of 1.8 liters. It has an internal heat exchanger that prevents the water used for brewing from coming in contact with the water stored in the boiler for steaming or hot water dispensing. With its commercial style design you can brew and steam or dispense hot water whenever you want to. This is especially important when entertaining or when used in a commercial application.
3-Way Solenoid Valve
The 3-way solenoid valve is a commercial feature that relieves the water pressure off the coffee when the brew switch is turned off. This serves two functions; it dries out the coffee to prevent dripping and makes it easy to knock the coffee out of the portafilter with one knock. It deposits this water into the drip tray.
High Quality Controls with Temperature Ready Light
The easily programmable controls are a breeze for anyone to operate. There are four buttons that, when programmed, will measure the amount of coffee going into your cup and shut off by itself. This allows you to focus in on creating the perfect froth while the machine takes care of the espresso. There is also a main power switch and ready light that lets you know when the machine has achieved the proper pressure for operation.
The Expobar Office Control has a 5-button touch pad for activating the pump and programming your favorite drinks. Four of the buttons are available to program to automatically dispense the desired volume of water.
We always preheat cups when brewing espresso. A non-preheated cup will immediately suck the heat out of the espresso thus robbing you of maximum enjoyment. The cup warmer on the Expobar will hold up to 14 espresso cups. It is a passive type heater, which means it is heated from the residual heat of the boiler.
Features & Benefits: Frothing and Hot Water
Hot Water Dispenser
A hot water dispenser is excellent for preheating cups or supplying hot water for tea. The knob on the right side controls the flow of water through the hot water dispensing wand. Just like on the large commercial machines the wand is mounted on a ball joint and can pivot in any direction.
The steam wand is long and is high enough off the counter to easily fit any frothing pitcher without having to tip it. It is mounted on a ball joint that can swing in any direction.
Features & Benefits: Care, Maintenance & Other
A 2.75-liter reservoir is easily removable for cleaning or filling at the sink.
Multiple Safety Switches and Controls
If the water level in the boiler gets low the electronic controls sense this and turn the pump on to automatically fill the boiler. If the reservoir runs out of water a CPU board will turn off the heating element to prevent overheating. A manual reset high temperature switch is located on top of the boiler as a secondary safety switch.
Boiler Pressure Control
The boiler temperature/pressure is controlled through a professional grade pressure controller. It senses the pressure in the boiler and turns on the heating element in the boiler as the pressure drops.
Back flush the Expobar at least every few days. For commercial application you should back flush it at the end of every day. It is a simple process that takes only a few minutes. Put a blank filter basket into the portafilter (supplied) and add a tablespoon of cleaner. Install the portafilter into the machine and turn on the pump. The pump will be noisy as it starts and will start to quiet down as the pressure builds. When the pump has quieted down, turn off the brew switch and the cleaner will be blown up into the brew group, through the 3-way solenoid valve and down into the drip pan. Do this until the cleaner that is being directed into the drip pan is just free of coffee colors. Finish the process by rinsing out the brew group.
The steel frame compliments the highly polished stainless steel housing and cup warmer. The drip grate is stainless steel. The plastic drip pan holds up to 32 ounces of liquid.

Three cups came with my Gaggia Classic. Two of them are larger - one having a large screen on the bottom and one with a small screen. How should they be used? Thanks
There are two pressurized baskets that are to be used with ESE pods. You will notice a single pin sized hole in the bottom of these two baskets. The third basket is a commercial sized double shot basket that is to be used with preground espresso or freshly ground espresso.
I've had our Gaggia Classic for about a month. The first few weeks it was working great. After pulling a shot the puck would be dry, no dripping after pulling the shot. Recently when pulling a shot, espresso continues to drip from the filter, sometimes a few drips sometimes a stedy stream. When I pull the filter out, there is standing water. I tried cleaning the machine with descaler as well as taking the shower head apart and cleanig to no avail. I read that after shutting down you should hear a rush of water, the solonid valve working. When I run the machine with just the filter and no grounds in the filter, I hear the rush and water coming out of the vent as it should. However, when I run the machine with grounds in, this does not happen. I started changing the grind level this morning but the issue persits. Wondering what else I can try, thanks!
Out of curiosity, are you brewing with the pressurized filter basket (the one with the little pinhole at the center) or the "commercial style" basket? If the former, you won't typically experience dry pucks post-brew due to the the basket's inability to displace the water in the puck with air; there's only a single hole, so not enough air can rush in to push the water out. With the commercial style basket and its larger number of holes, this is not normally the case. Other causes of this could be an excessively fine grind, too much tamping force, too much coffee, or some combination of these factors. Try lightening up on one or all of these three factors. The lingering water and dripping (caused by the water above the puck heating to the point of producing steam, the pressure of which is enough to push it down through the puck and out fo the spouts) leads me to think "too fine" or too inconsistently fine a grind or "too heavy" with the tamping force.
The reason you can typically get a nice "surge" with an empty basket, but not a loaded or full basket, is due to the additional "springy" force of the air being compressed in the basket by hydraulic pressure; When the pump is switched off, some of the air being squished into the basket springs back, pushing the water out with a bit more force than it may when the basket is filled.
Thanks for your response,
I have been using the pressurized filter basket, I will keep your notes in mind. I am thinking about getting a small scale to make sure the amount of coffee stays consistent. Been trying to play around with the grind since it is the only factor I can really change at the moment. I like to think that my tamping force is fairly even between shots, but I could be wrong. Thanks again for your help!
Until a month ago, I was very happy with the consistent running of my Expobar Office Control. I installed a thermosyphon restrictor on it about 2 years ago. Last month, it started acting up. When I prime it before pulling a shot, there used to be about 6 ounces of water flow during about a 45 second prime. Now there is 2-3 ounces. And less crema on my shot.
Also, it now takes about 20 seconds before the shot starts flowing, it used to start in about 5 seconds.
Is it just running too hot for some reason?
There could be a few things that cause this. But most likely there is a leak from the air remover or the OPV when the machine is sitting idle. There are two tubes going into the reservoir. Remove the one that is not the water intake tube for the pump and put it into a dry cup. Brew a shot and watch as water comes out of the tube and into the cup. Then dry the cup, put the tube back into it, and let the machine sit for an hour and then check to see if you have water dripping out of the tube. If you do I would recommend purchasing a whole Pump, Air Remover and OPV assembly. Even though the pump may be fine, I would recommend replacing it while you have the machine apart. That is if you want to do it yourself. If not we are happy to do it for you.
We've had our control for 18 months. The buttons get 'out of control' from time to time, with the lights randomly flashing on and off and even a shot being pulled without our initiating it. In the past just unplugging it for a few minutes reset it and we were on our way again. Now the problem persists no matter what. Any thoughts on what the next step is?

I love my old Expobar Office Control (?circa 2003) but I am afraid it has finally died. I hope to revive it with some parts and care if possible. When turned on, it no longer heats up and the pump does not make it's lovely priming sound. Oh, and the program buttons haven't worked in about a year - I just use the "continuous" button to start and stop a brew cycle. Is this machine worth fixing? I will be so sad to say goodbye.
Hello Pauline! This is a very good question. As we get questions that revolve around this with other brands also. With the age of this machine, if you were to send it in for repair, I would suggest purchasing new. If your handy with doing things yourself and can diagnose the issue, I would keep the machine. Either way I would give our tech department a call 1-888-411-5282 option 3. If you decide that repair, just isn't going to work for you. Any of us in sales would be able to help you. Have a wonderful day!
I need a new reservoir cover for my 10 year old office control. Has anyone found one??
You can replace the water tank with a Rubbermaid/Tupperware cereal container. The water tanks and lids for the old style Office models aren't available anymore.
I have had my expobar office for about 4 years. I am having a problem with the steam. It is sending a large amount of water out before it will get the steam going. Approximately a full cup of water. Any ideas?
By "A full cup," do you mean one full liquid measure cup (as in, 8oz), or a demitasse? While it is normal for some water to come through during the purge, seeing a significant increase in the amount of water typically suggests that the boiler is either over-filling or running too cool. As the machine determines the proper fill level by the conductivity of water, the former can be caused by low-mineral content water (reverse osmosis processed, distilled, or otherwise *heavily* filtered water can all reduce the mineral content to the point where it can't conduct electricity correctly). Alternatively, you may want to consider removing and cleaning the water level probe to ensure that it is clean and able to conduct properly--any surface scale on this part could result in an altered fill level (typically, overfilling). Finally, you can always try adjusting the pressurestat to up the boiler's operating temperature slightly. I would take this step carefully as it would have a direct effect on the brewing temperature of your machine--you can always try measuring the in-cup temperature of a few 2oz pulls, comparing them against the new Compare-o-matic. If the shots are below temperature, you can safely increase the steam pressure slightly. if the shots are on target, you'll likely see a decline in brew quality, and would be trading some additional water during the purge for a change in the drink itself. Let us know if you have any questions about how to attempt any of these processes!

I'm curious, what's the difference between the Expobar Lever and Control machines?
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.
I have filled the tank and let the machine try to fill at least 6 times now and it still is not filling. Both tubes are in the bottom of the tank. What is wrong?
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.
The thermostat on my Office Control is very temperamental. How easy is to replace or adjust?
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 doesnt seem to do the trick, we can send you a replacement along with instructions - another easy process.
I have the EXPOBAR Office Control machine. It's about two years old. (It has been a great machine!!!)
Problem is, I can't find my owners manual. I need to re-program the some of the flow buttons. Can you tell me where I can get a replacement manual?
We can email you a copy of the directions if you give us a call at 888-411-5282.
If the Expobar is not going to be used for a week, should the reservoir be drained or any other maintenance done?
If youll be away from the machine for a week, I would recommend turning it off and unplugging it for that time. Its also a pretty good idea to empty the water reservoir beforehand, as you wouldnt want to use that week-old water when you come back anyway. In addition, when you do return youll want to run an entire reservoirs worth of fresh water through the machine to get out the water thats been sitting the boiler while youre gone. After that you should be good to go.
What water temperature should this machine brew at? I've read that around 199-203 degrees F. is best.
Espresso should be brewed in the 200ºF range. Our tests have shown that the Office Control brews consistently at 198ºF, so its 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.
I'd just got my Expobar Office Control. Is that normal that the brew group is very tight? I can't get it turn all the way to 6 o'clock position as your supplement instruction has suggested. I also have a hard time to turn it loose after the coffee brewing.
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 oclock 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.
