OverviewBack to Top
The Expobar Office Pulser commercial espresso machine is one of a kind with a combination of low cost and high quality design and construction. It is a machine that will last a lifetime in home use and is suitable for the office, coffee kiosk, small cafe or hotel coffee bar. It can brew and steam at the same time making it ideal for any type of home use, small deli or bagel shop. The separate hot water dispenser and steam wand are mounted on a 360-degree ball joint. The group head is comparable to the renown E61 group head with pre-infusion and thermal siphon for maximum temperature stability and aroma extraction. Its electronic boiler controls, safety switches and internal components mirror those of the larger commercial espresso machines. The Expobar Office Pulser is short enough to fit under a 16” high cabinet and is only 9.5” wide. The stainless steel housing gives it as much form as it has function. The accessories include a chrome plated brass portafilter, tamper, single shot filter basket, double shot filter basket and a 7 gram coffee scoop.
Please Note: Regulations for commercial use vary between states. Be aware of your local requirements. Machines carrying an NSF approval are labeled as such. Please visit our policies page for warranty information.

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 prevent the water used for brewing from coming in contact with the water stored in the boiler for steaming and 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 controls are easy to operate and understand, no training necessary. Just turn on the main power switch and the boiler will fill with water on its own and start to heat up. When the temperature ready light goes off you are ready to go ahead and start brewing.
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.
One year parts & labor warranty
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 three 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 and the drip pan is plastic that holds up to 32 ounces of water before it need to be emptied.
My expobar will not turn on. I checked the electrical outlet (which is fine). the on/off button flickered once, but no longer flickered and remains unlit when in the on position. What can I do?Answer on our Community →
Sanfam aswered:First and foremost, how old is the machine? With time, these power switches can fail from normal wear and tear. Alternatively, make sure the water tank is completely full--a not-quite-empty tank might weigh just enough to allow the safety switch under it to pop up and cut power.
Mo aswered:it had plenty of waterf. The machine was purchased in August 2010.
I bought my expobar about 1 year ago. The water is not passing through anymore . I dont know if it is a problem with buying expresso that is too finely ground or have heard it might be water pressure not strong enough. The expresso looks like sludge, n
I bought my expobar about 1 year ago. The water is not passing through anymore . I dont know if it is a problem with buying expresso that is too finely ground or have heard it might be water pressure not strong enough. The expresso looks like sludge, not a hard cake when this happens. Did nt...Answer on our Community →
Maggie aswered:It definitely sounds like the grind is too fine-are you able to get water flowing through the group head without your portafilter on? If so, I'd suggest making your grind a bit coarser, or having it ground a bit coarser wherever you purchase your coffee from. I would also suggest that you...
The frothing wand on our Expobar pulsar (4 years old) is not working. We get water from both the portafilter and the hot water dispenser, but nothing from the frothing wand. And suggestions? Anyone in the Raleigh, NC area that handles Expobar repairs? Thanks!Answer on our Community →
Whole Latte Love aswered:Thank you for your submission. It is quite an easy fix. If you are able to get liquid from the hot water wand this is a good sign. Steam and hot water and drawn from the same place in the machine. Remove the tip of the steam wand. You can do this by unscrewing it. There is a small white...
How do I get decalsified water. I do not like the taste of softened water, and I don't have a softener anyway. Can I use Britta water?Answer on our Community →
Whole Latte Love aswered:Decalcified water is softened water, and the best way to get it for use with your Expobar is to either use the water softener that came with the machine or purchase the Rancilio softener that we carry. Although Brita filtered water does have a better taste than hard water, it only filters out...
Can a person make a cup of regular coffee with these machines if they wanted? Would that be a waste of coffee or would it be a good cup of coffee?Answer on our Community →
Whole Latte Love aswered:Although an espresso machine cant make traditional drip coffee, it can make 2 things that are very similar: cafe americano and cafe crema. An americano is simply a double shot of espresso with an added 6 to 8 oz of hot water. Although it sounds like it may taste watery, the concentrated flavor...
what is the difference between the Pulser and the Lever versions of the Expobar?Answer on our Community →
Whole Latte Love aswered:The 2 machines are very similar, and the largest difference between them is going to be their brewing and solenoid valve release controls. Since the Lever machine has an E61 brew group, it has a lever that must be put in the up position to begin brewing and then pulled down to stop. In addition,...
I just received my Expobar Office Pulser from you and I'm wondering if I have to run cooling flushes through it before making an espresso. By looking at other web sites (for example coffeegeek.com) I inferred that any HX machine needs such cooling flushes. The manual (including yours) doesn't say...Answer on our Community →
Whole Latte Love aswered:Although its not listed in the manual, running water through the brew group and empty portafilter before brewing is a great idea. This helps to ensure that all of the external components of your espresso machine are at the proper temperature for a great extraction (and you can dispense the water...
Can you give any comments on warm up time for this machine? I'm looking for a semi-auto machine that heats up quickly and easily froths milk for cappuccino. I've looked at Gaggia Classic and Rancilio Silvia. It seems several reviewers mention the Silvia takes some time to warm up.Answer on our Community →
Whole Latte Love aswered:The heat-up time for the Expobar is going to be about 15 minutes, whereas the Silvia and Classic average around 6 minutes. The time it takes a machine to heat up is directly related to how large its boiler is - the larger the boiler, the longer the heat-up time - which is why theres such a...
Hi, got the Pulser - love it. Just a quick question about the water tank. The manual states to fill it to the top of the indicator window, but my machine has no window. How full can I fill my water tank?Answer on our Community →
Whole Latte Love aswered:You can fill the water tank nearly to the top, but I wouldnt recommend filling it all the way to prevent spillage.
A while ago we bought the Expobar Office and are quite happy with it. Now the water catcher starts leaking. We would need a replacement. Where can I buy this?Answer on our Community →
Whole Latte Love aswered:We carry all Expobar parts and would be happy to send one to you. Simply call us at 888-411-5282 to place an order.
Water builds up in the steam wand when the unit heats up. I must discharge the hot water into the basin before putting it in the milk to steam. Is this build up of water normal for this machine? ThanksAnswer on our Community →
Whole Latte Love aswered:This is normal, and probably means that the machine isnt fully up to pressure yet, or that the condensation in the steam valve has not been released. When the machine is up to temperature, and you are ready to steam, We would recommend opening the steam wand and letting any water that may have...
The reservior is removable from where? front, or back? and is it possible to remove without disassembly while the machine is in operation?Answer on our Community →
Whole Latte Love aswered:The reservoir is removable from the top left side of the machine. It is possible to remove it without major disassembly (the cup warmer plate will simply need to be lifted off to access it), however, you shouldnt do this while the machine is brewing. This is because the low water level sensor is...
When I go to pull a shot it takes a full 15 seconds for water to begin to pour from the group. When I go to the next shot it is instant. Do you know why this could be?Answer on our Community →
Whole Latte Love aswered:This may be an indication that a part needs to be replaced. Please contact our tech department at 888-411-5282 so that we can thoroughly diagnose the problem and provide you with the appropriate solution.
