Overview

Back to Top

The Commercial Expobar Office Lever Semi-Automatic Espresso Machines are a welcome addition to the Expobar line. Its traditional styling, compact size, and commercial strength make this a leading competitor in the semi-automatic lever operated espresso machines. It is a machine capable of everyday use in the coffees shop, small cafe or hotel coffee bar, and in the kitchen of the at-home barista.

The commercial style copper boiler has all the features that are found on larger commercial machines. It allows simultaneous brewing and steaming, enabling smooth operation. It has both a steam wand and hot water dispensing wand that adjust laterally so that they can swing in either direction for easy access.

With commercial capabilities its size makes it convenient for those who want great espresso without sacrificing a large amount of counter space. It is 15” tall, 10.25” wide and 17.5” deep.

The E61 brew group provides pre-infusion and a thermal siphon for maximum temperature stability and aroma extraction. The Expobar Office Lever now has 2 pressure gauge displays that allow users to easily monitor both brew and boiler pressure

The eye catching highly polished steel housing is as durable as is it beautiful.

The accessories include a chrome plated brass portafilter, tamper, single shot filter basket, double shot filter basket, backflush disc 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

Features & Benefits: Coffee

Heavy Duty Commercial Portafilter

The portafilter is commercially designed and made of chrome-plated brass, which is excellent for temperature stability throughout the brewing process. The machine comes with a double spout portafilter.

E61 Commercial Brewing Group

This is the portion of the machine that the portafilter locks into. It is made of chrome plated marine brass, which provides a superior brewing environment with maximum heat stability and component longevity. The commercial E61 brew group is known throughout the industry to be one of the best due to its thermal siphon design. The thermal siphon circulates hot water from the boiler to the group thus keeping it piping hot in times of inactivity. Its temperature stability is as good as it gets.

Progressive Coffee Infusion

The brewing system provides a smoother delivery of pressure then a traditional vibration pump. Not found on other machines in this class and was noticeable on our own technical analysis - a nice feature.

Commercial Design Heat Exchanger Boiler System

The large 1.8-liter copper boiler with brass end plate takes about fifteen minutes to heat up. Once it is up to operating pressure it can brew continuous espressos all day long. Due to the boiler’s large size it can also do many lattes and cappuccinos without any down time. The heat exchanger allows you to brew and steam at the same time.

Unique Lever Control w/ 3-Way Valve

There are only two controls on the Office Lever. The main power switch is located on the upper left, and a lever on the right, which operates the brewing process and solenoid valve. The main power switch is a lighted rocker switch, when the machine is turned on it glows red, and the boiler immediately starts to heat up. When the pressure gauge reaches 1 bar of pressure, you are ready to brew. The only control you will need to operate is the lever that is located just to the right of the brew group. This is a very unique system because this lever actually controls a valve in the brew group. Press the lever up to open the valve to start the water flow through the coffee this also activates the pump. Press it all the way down when you are done brewing and it opens a valve that relieves the water pressure off the coffee. 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. This valve that you are operating is a very high quality piece of equipment that gives you more of a hands-on system that most standard pump machines.

Low Water Cut Off

The Office Lever has a low water sensor mounted in the water reservoir that will turn off all power to the boiler if the water level gets to low.

Pressure Controller w/Pressure Gauge

The boiler temperature/pressure is controlled through a pressure controller. It senses the pressure in the boiler and turns on the heating element in the boiler as the pressure drops. You can visually see the boiler pressure through a pressure gauge on the front of the machine. When the needle in the gauge is between 1 and 1.5 bar of pressure you are ready to brew and steam. If the pressure controller ever gets out of calibration you can tell by the pressure on the gauge. Just give us a call and we can easily walk you through resetting the pressure controller.

Pressure Gauges

The Expobar Office Lever now has 2 pressure gauge displays that allow users to easily monitor both brew and boiler pressure making it easier to monitor the extraction parameters.

Electronic Controls

The "Electronic Boiler Refill Control" is the brain of the machine. It uses probes mounted inside the boiler and on the base plate below the reservoir to sense their water levels. It uses this information to control the operation of the pump for refilling the boiler when necessary. It will also turn the boiler off for safety if the reservoir or boiler runs out of water.

Cup Warmer

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 Expobar Office Lever has a passive cup warmer located on the top of the machine. The cup warmer is 10" x 10".

Features & Benefits: Frothing and Hot Water

Hot Water Dispenser

The Expobar Office Lever has a separate hot water dispenser. Just turn the knob on the right and the boiler pressure will push hot water out through the dedicated wand located on the right side.

Steam Wand

The steam wand is high enough off the counter and long enough to work well in any situation. It also rotates the left so that it you have plenty of room to work.

Features & Benefits: Care, Maintenance & Other

Water Reservoir

The 2.75-liter reservoir may be removed for cleaning. The easiest and safest way to fill the Office Lever is by removing the reservoir.

Maintenance

Back flush the Expobar Office Lever at least every 7-9 days. 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 the control lever up to start the pump. The pump will be noisy as it starts and will quiet down as the pressure builds. When the pump has quieted down, turn the lever all the way down. This will cause the cleaner to be blown up into the brew group, through the three-way 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.

Housing Construction

The Expobar Office Lever is breathtaking. Polished steel housing, cup warmer and front panel. Stainless steel drip grate and drip pan. Heavy powder coated steel frame and chrome plated brass brew group.

One year parts & labor warranty

Water softener cartridges

When should the softener cartridge be replaced and what material(s) are used in the cartridges?
Tracys aswered:
The water softener cartridge is rechargeable and does not need to be replaced. The recharging should be done at least once a month depending on the machine usuage. The catridge is recharged using a mixture of salt and water.

Water filter replacement

Unfortunately, when I removed the water filter to replace it with a new filter, I did not pay attention to which of the 2 rubber tubings the water filter attaches.  Does it matter?
Maggie aswered:
It definitely does!  Usually, the longer tube in the water reservoir is the intake hose, where you want the filter to be.  The intake hose may also have a notch cut out of it.  
sgd aswered:
Thanks so much.  That is so helpful to know!

My 5-6-year-old Expobar Office Lever just started emitting a hissing noise and steam from the top of the machine.

Noise and steam start as soon as the machine heats up and continue until the machine is turned off and has cooled down again.  It is working OK but I would like to know if there is anything I can do to stop the steam/noise, and what this problem means.  I recently moved to Manila, The Philippines.
Maggie aswered:
It sounds like you might need to clean out the safety valve and/or the vacuum relief valve, or even replace one of them-I'd suggest cleaning first, it's very easy and will usually clear up the issue.  For instructions, please contact our Technical Support team at 1-888-411-5282, option 3... more

Any suggestions as to why the first shot pulled has the best crema, but subsequent ones tend not to? (our Office Lever is approx. 10 years old, we pull 2 doubles/day, have changed brewhead gasket twice w/no leakage around brewgroup, and let it come to temp/pressure for 30 minutes or more before...

Is the gauge on the machine going into the red zone? The longer the machine sits the hotter it will get. Older machines can overheat when their pressure stat begins to fail.

Question by chih chou c.

I have never got the 9-10 bar brew pressure indication on the brew pressure gauge,if I tamp harder in order to make it to be reached 9 bar,nothing will be pour out, is there somewhere leaking?
techkathy aswered:
if your grounds are too fine or you are tamping too hard (or a combination of the 2 things) then nothing will come out of the portafilter. I would recommend making the grounds just a tiny bit coarser and experimenting with the tamp pressure you are using.

Have you tried removing the water softener filter to see if the machine has lost its prime? There should be a water filter on the end of one of the tubes in the water tank. Pull the filter off of the end of the tube and try again. The machine should start to draw in water. Worst case - the... more

Question by David C.

I have an Office Lever Plus that is about a year old. I see that the WLL has created a copper washer with a hole in it to help with the high temperature of the group head. My question is, can I purchase one of these to put in my machine? Thanks David
A aswered:
David, Looking up your order, I see that you purchased that machine in Feb of 2012. We had already begun modifying the machines with the new thermosiphon washer before that point. So your machine already has it!

Question by Rick G.

Well I pulled the trigger and got this machine. I am so excited to get it on my counter and start learning all there is to know about it. I also got the Rancilio Rocky Doserless grinder. My question is, what do you recommend I start with on the grind setting?
Sanfam aswered:
With a Rocky grinder, consider starting at 9-10--this should be a good starting range on a new machine. However, remember that each grinder is more-or-less unique, I would take this with a gain of salt and adjust as needed.
Rick aswered:
Thanks Sanfam! I got my grinder and Expobar last night and tried it out this morning. First pull was at about 30 seconds on the setting of 9. I changed the setting to 12 and it pulled wonderful shots in 22 to 24 seconds. What a wonderful pair. I am so happy I went ahead with the upgrade.

Question by Rick G.

Is there a way to attach a drain line for this model? I know it is possible on the plus model.
A aswered:
Rick, Because the legs on the "non-plus" model has the shorter legs, there is not enough clearance for the drain kit that you would find on the "plus" model. You could probably rig something up for it - but the Expobar parts for the actual drain kit are too large to fit under the machine as it is... more

Question by Ralph N.

After initial warm up the ready light goes off then back on every couple of seconds. Is this the expected behavior or should it remain off completely? The same happens during the brew cycle.
Craig aswered:
While I don't have an Expobar, this is typical of other machines and indicates the heating circuit turning off and on to maintain the correct heat on the boiler. When you are preparing to steam, does the light stay on longer? If so, this is normal, due to the extra heat required by the boiler to... more
chih chou aswered:
Please check the boiler pressure. the heater should be turn off once the pressure reach 1.0bar the light goes off, and light on again when the pressure drop down to 0.8bar.

Question by Ralph N.

How do I tell the difference between the single shot and double shot baskets?
mjackson aswered:
The double shot basket is deeper and also the single shot will have a more tapered bottom.

Question by Ralph N.

My portafilter does not turn to a full 90 degrees easily, if I remove the basket it works however with the basket in place it only reaches partially to its indicated final position? Is this expected?
mjackson aswered:
Ralph, It is expected as it is new. It will break in as you use it and you will get closer to 90 degrees. As long as it is not leaking it is on tight enough.

Question by Dean H.

What size metal tamper does the expobar office lever need? I thought I read somewhere it was a 51mm but I'm not sure.
Whole Latte Love aswered:
The Office Lever will require a 58mm tamper. We carry several in that size, each of which you can learn more about by following the links below.

Question by Dean H.

Does this boiler have the heating ellements actually in contact with the water or are they incorporated into the boiler body, thus heating it & the water without the elements comming into direct contact with the water?
Whole Latte Love aswered:
Due to the construction of the heat exchanger boiler, some water does come in contact with the heating element. The water that does come in contact with the heating element is used for steaming and hot water. On the other hand, water thatÂ’s used for brewing does not touch the heating element.

Question by Dean H.

The Expobar Office Lever espresso machine I purchased mentions your ready to brew when the indicator reads 1 Bar to 1.5 Bars. My local Brista tells me that 9 Bars of preasure are required for propper espresso extraction. Is 1 Bar of preasure on this machine's indicator actually equal to 9 Bars...
Whole Latte Love aswered:
The pressure gauge on the machine is an indicator of the boiler pressure (directly correlated to temperature). That gauge will generally read from .9-1.5 bar of pressure during normal operation. The pressure that the pump produces for brewing should be between 8-9 bars of pressure, like your... more

Expobar Office Lever running too cool?

I've recently upgraded to the Expbar Office Lever from a Gaggia Classic.  I am getting pretty good results from the new Office Lever, and I am having a blast using the machine.  However, I am running into a curious problem.  If I allow the machine to idle for more than an hour, without any flush,...
