The Expobar Brewtus IV-R is one of the most advanced semi-automatic espresso machines available to the prosumer and light duty commercial market. This model features two independently operated boilers, one for brewing and the other for steaming.  By having two boilers, result in greater brew temperature stability and superior steam pressure.

Exclusive to the Brewtus IV models, is a dedicated control switch that lets you deactivate the steam boiler and operate just the brew boiler. Exercising this option will significantly decrease heat-up time; in fact, the Brewtus IV-R can go from a cold start to 201 degrees, ideal brewing temperature, in about 15 minutes. If you decide that you want to froth some milk, flip the steam-boiler control switch and in approximately 10 minutes the steam boiler will be ready to steam. This smart system can lower operating costs and result in quicker warm-up time, since you won’t have to wait for the steam boiler to heat up.

Like its predecessor, the Brewtus IV-R features a Gicar PID (Proportional-Integral-Differential) controller and rotary pump. The PID control lets you monitor and adjust brew-boiler temperature to suit your preferences. Further contributing to the Brewtus’ heat stability is the chrome-plated brass E61 brew group with thermo siphon system. The Expobar Brewtus IV-R is equipped with a commercial rotary pump for smooth, quiet operation; it is recommended for high-end home use.

Note: The Expobar Brewtus IV-R does not have an on-board water reservoir. It is designed to be directly plumbed into a water line.

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.


No-Burn Steam Wand and Hot Water Dispenser

The steam wand is insulated and will remain cool to the touch, even when it is in use. It is equipped with a one-hole commercial steam tip that allows for maximum control when steaming or frothing milk. The hole in the steam tip is sized so that you can get non-stop steam from the steam wand. This Expobar model also has a separate hot water dispenser for your convenience. Both the steam wand and hot water dispenser are mounted on ball joints and can be rotated to accommodate different-sized cups and pitchers.

Commercial Rotary Pump

The commercial, 120-watt rotary pump is designed to work with a plumbed water line. In most cases, you will not need a pressure reducer as it can run on incoming water pressure between 5 and 65psig. You can also drop the stainless steel water intake line into a large water jug, if you prefer not to plumb the Expobar Brewtus IV-R; but please be careful not to let the pump run without water, as this can cause damage to the machine.

Additionally, you can run a drain line from the drip tray to eliminate the need to empty it by hand. To set the drip tray up to work with a drain line, a hole will have to be drilled into the drain pan. We are happy to modify the drip tray here, at Whole Latte Love, or you can do it at home. If you set the machine up with a water line, we recommend that you also hook it up to a drain line.

Brew Boiler Shut-Off Option

If you only want to use the steaming and hot water dispensing functions of the machine, you can turn off the brew boiler. To turn it off, push and hold the "up" arrow on the digital display for 2 seconds, the display will then say "off." To turn it back on, just push and hold the "up" arrow for 2 seconds.

Manual Three-Way Valve

Lift the brew lever to start the pump and it will also open the three way valve and allow the brewing process to begin. When the extraction process is complete, lower the lever. The pressure and water in the brew group will be released into the drain pan, leaving you with a nice, dry puck. In addition, the three-way valve will allow you to easily clean the brewing components of Brewtus IV-R by backflushing the machine. We recommend that you backflush your machine every 7-9 days.

Steam Boiler Control Switch

A dedicated control switch, located on the front panel of the machine, lets you turn the steam boiler off. This allows you to run the brew boiler and extract espresso without having to wait for the steam boiler to heat up. You can expect lower operating costs with this unique system as well as quick machine warm up time. The Brewtus IV-R can be ready to brew in less than 15 minutes. Once the steam boiler has been switched on, it will be ready to go in under 10 minutes.

PID Temperature Control

The Gicar-built PID control is designed to keep brew boiler temps stable. You can also use it to adjust your boiler temperature to suit a variety of espresso roasts. The system sends pulses of electricity to the brew boiler to ensure that it is evenly heated, without over heating so that you can maintain a very steady brew temperature.

Housing and Construction

The Expobar Brewtus IV-R is a solidly built machine; it is encased in a heavy-gauge stainless steel frame. The polished mirror finish and classic styling gives this machine a stately appearance that will complement most home kitchens.


One year parts & labor warranty

Improved E-61 Brew Group and Portafilter

The Brewtus IV-R is outfitted with the renowned chrome-plated brass E-61 Brew Group, celebrated for its ability to offer unwavering temperature stability. It is backed by a state-of-the-art thermo siphon system that circulates hot water from the boiler to maintain group head temperature. New to the forth generation of the Expobar Brewtus machines is a concave pre-infusion chamber that allows hot water to be evenly distributed through coffee grounds for superior espresso extraction. Unlike conventional E-61 brew groups, this group head directs water through the brew group in a concentrated stream. Once the water hits the center of the shower screen, it floods back up into the pre-infusion chamber before being evenly dispersed through the coffee grounds for uniform saturation during the pre-infusion and brewing process. Accompanying the E-61 Brew Group is a professional chrome-plated brass 58mm portafilter as well as single and double-shot filter baskets.

Brew and Steam Pressure Gauges

The steam and brew-pressure gauges are located on the front panel of the machine for quick reference.

Double-Boiler System

The steam boiler and the brew boiler each have their own 1250-watt heating elements for fast, temperature-accurate performance. The boilers are made of copper and having two of them means that individual boiler temperatures can remain constant as you go back and forth between brewing and steaming. Each boiler is set to the appropriate temperature for its designated function. Double boilers also make it possible to brew and steam at the same time, which is perfect if you’re making a few drinks at once.

eric asked:

Hello everyone!

I guess this is a Brewtus water pressure question.  I just got my Brewtus IV-R from WholeLatteLove up and running, but I want to use a 5 gallon Culligan's jug as my water source rather than plumb it into the city water.  I know you can just dangle the steel braided line from the Brewtus directly into the 5 gallon jug, and in fact it works OK.  But I read somewhere that you can't do the manual preinfusion technique unless the water coming into the the Brewtus is under pressure, which you don't have just dangling the braided line into the water jug.  A guy  advised me to use a Floject demand pump as the solution, so I got one from them and got it hooked up.  When you raise the brew lever and water starts coming out of the group head, the Flojet pump detects a drop in the water pressure going to the Brewtus and turns on the water pump in the 5 gallon jug, maintaining water pressure in the line.  As I say, everything is hooked up and no leaks.  Theoretically, this solves the preinfusion issue by maintaining pressure.  The issue I have run into is that the Flojet, when it kicks on (which is does, immediately) then cycles on and off repeatedly.  The Flojet manual says that when you use this pump with coffee brewing equipment [not specifically a Brewtus], the coffee machine likely has an inlet pressure regulator that "limits incoming pressure to  approx. 90-100 psi. If you intend to use the Flojet BW system with one of these brewing machines, you should remove the brewing machine's restrictor device....Failure to remove the brewing machine's restrictor may cause the Flojet to cycle itself  off and on  repeatedly, leaing to premature motor failure of the Flojet BW unit."

Before anyone asks, I don't know what the water pressure is coming out of the Flojet.

I thought I was on to a great solution, but now I am not so sure.  Any suggestions?




Answer by Sanfam:

Thank you for your message.  First and foremost, it sounds like you need an accumulator of some sort to act as a "buffer" of some sort between the flojet and the machine.  The issue you're encountering is that you do, essentially, have a variable restrictor attached to the machine in the form of the coffee puck.  When you list the brew lever to start the pre-infusion process, the puck saturates with some of the water in line line and the pressure likely drops enough to trigger the pump to switch on; Pressure then increases until the pump is switched off, where the cycle then repeats.  Odds are, the manual is referring to using this not as a direct source for brewing espresso, but rather as an auto-fill for a drip brewer's reservoir or as a boiler refill aid, where it would never experience the slow, but persistent "drop" that is associated with releasing water for pre-infusion.

Basically, research adding an "Accumulator" to the mix, as it would potentially help.

Wendy asked:

I plan to get this Expobar Brewtus IV R expresso machine. But my concern is about the water source. Does any specific water filtration system need to be used with this machine? I live in an apartment so I plan to just set up a 2 gallons reservoir on the side. I'm not sure what kind of water I need to use in order to not damaging or causing scale to the machine.

Answer by Sanfam:

Regarding a water softening system, we do not currently have any specific information on in-home softeners that we can recommend for installation.  However, the industry does have a few prominent players, such as BWT, who are well-regarded and may offer inline softening systems scaled to your intended use.  Your best bet is to consult with a local plumber, as they would most likely have the answers you're looking for.

James asked:

Our machine has been idle for several months. I fired it up today. I tried ti run some water through it but nothing came out of the group head, I had good steam and hot water. The pump is running. The pressure looked normal. I tried backflushing but it acted like no water was moving. I ran Cafesa in it. After five runs the Cafesa was still in the portafilter. It was full of water. I went through the rinse and removed the portafilter. Now water trickles through but not nearly enough to brew with.

Does this sound like something I can fix by continuing to back flush/clean? Can I do anything else?


Answer by Garth Whelen:

If you're cleaning, try CLR (calcium lime remover), I have to clear out my breville machine about once a year from hard water build up. But, if your steam nozzle is working, try a t'latte infuser


Rob K asked:

My Brewtus IV pulls a double shot in about 12 seconds.  I tried a bottomless porta filter and it sputtered coffee everywhere.  I have fresh coffee and use a compak k3 grinder.  The brew pressure indicates between 8 and 9 bar.  Any ideas

Answer by mjackson:

Not sure what is up with bottomless portafilter please call our technical support line.

As far as the shot timing goes you need to make your grindd finer and also read these articles which should help





Eddie Woods asked:

is this machine nsf certified? if not does it need to be to use it in a comercial setting in vermont?

Answer by Sanfam:

The Expobar models are not NSF certified at this time.  I'd suggest contacting our Commercial Sales team for better-targeted recommendations for your particular brewing environment.  They can be reached by phone at 888-411-5282, Option 1

James asked:

Beginning today, I get the "A2" indication immediately when I turn the machine on. The Manual I have does not contain anything about it, so does anyone know what it means and how do I resolve it? There is water

Answer by Maggie:

James, thank you for your post.  An A2 error is an issue with the temperature probe-please contact Technical Support for further assistance.  Technical Support is available Monday through Friday, 9:00 a.m. to 6:00 p.m., and Saturday, 10:00 a.m. to 3:00 p.m., EST, at 1-888-411-5282, option 3.  

AverageJo asked:

Is there a Brewtus IV-R Manual in E N G L I S H ? I downloaded the manual from the WLL website but it's in Spanish or Italian, I can't tell which.



Answer by AverageJo:

It's been a few weeks since I received my Expobar Brewtus IV-R. A manual in ENGLISH was included with my new machine, HOWEVER the downloadable manual that appears on the Whole Latte Love website in SPANISH was not included with my new machine. These are two different manuals. The one in English that was included with my new machine is a simple how-to operate type manual. It doesn't contain the mechanical schematics that the downloadable manual on the Whole Latte Love website features.

I feel that BOTH manuals are useful to the end-user because there will most probably come a time when the machine will need to be repaired and/or parts replaced. Since the Expobar is a product that Whole Latte love features as one of their cornerstone prosumer models, it would be advantageous to give both manuals to the consumers at the time of purchase. This would alleviate the need for hours of frustration and panicked phone calls to Whole Latte Love trying to figure out what's wrong with the machine in the future, which is what I went through with my Brewtus II before learning about the Google Brewtus group. I was able to get a very detailed manual that one of the members had assembled there. For anybody who has an older Brewtus, here's the link:  https://groups.google.com/forum/#!forum/brewtus

I also find it annoying that so many people have posted questions to the Whole Latte Love group and there are very few with posted answers. There has to be some better way to handle this dilemma.

brianw asked:

We are plumbing a house for this machine. What diameter line and fitting should be used to plumb it (we dont want to starve the pump). Looks like we should install a filter and regulator in line as well. Is copper considered good? Our water supply will come from under the kitchen sink so we can install a shut off valve. Thank you.

Answer by Sanfam:

As the flow rate required by this machine is relatively low, you'd be ok with 1/4" hose feeding the machine.  We supply all machines with a brass adapter that converts the 3/8" female BSP fitting to a more usable 3/8" male Flare fitting. With regard to water regulators, you'd be best setting the upper limit at 30-40psi.  In general, the pump has a relatively low flow rate (being designed to dispense only a relatively low volume of water over a long period of time), so you shouldn't have any trouble with almost any standard water source. 

brianw asked:

We are going to run a line from under the sink, thru a cartridge filter to the IV-R. What diameter lne needs to be ran to supply this espresso maker? What fitting should be on the end of the line?

Answer by Sanfam:

As the flow rate required by this machine is relatively low, you'd be ok with 1/4" hose feeding the machine.  We supply all machines with a brass adapter that converts the 3/8" female BSP fitting to a more usable 3/8" male Flare fitting.

Answer by brianw:

Is there an installation manual available in english that provides instructions to a plummer for maiking the water supply available? Maybe a drawing or picture of an installation? It seems that water supplies for ice makers, etc are in boxes behind the fridge and this will be a supply line behind a cabinet or backsplash. How are the lines brought up so they look good and are secure?

James asked:

I have a Expobar Brewtus IV-R with Rotary Pump (nice). I'm moving to another apartment in NYC. I will move the Brewtus in the factory box. Do I need to empty the tanks? If so, how?

Answer by Maggie:

If you click on this link http://www.wholelattelove.com/policy_landing.cfm#shipping and scroll down just a bit, it will give you the information on how to drain the boiler. We definitely recommend draining the boiler before moving, especially if it is going to be stored for any length of time before being used again.

Answer by James:

I tried these instructions and it didn't drain but a couple of ounces of water from the steam wand and steam head. And of course, this is a two tank machine, so these instructions would only drain the steam tank, not the coffee tank, at best. By the way, I am not storing at all - just moving, if that makes a difference.

Michael R asked:

I am interested in the Expobar Brewtus IV-R but I am concerned about the lack of reservoir. I plan to plumb it in eventually, but expect to be moving soon, so I don't want to plumb it into the house I am currently in. Can I just drop the water line into a pitcher for now and operate it like that until I move?

Answer by Maggie:

You can absolutely use a separate reservoir with no issues. Just make sure that, when you do plumb it in somewhere, that you install a water pressure regulator on the line going into the machine. It needs to be no more than 40 PSI.

Daniel asked:

Looking to start a small coffee shop, but have never owned an expresso machine. I was wondering if the Expobar Brewtus IV-R would be a good machine to learn the art of making quality coffee at home before we open up our business? I also would like to know how many cups per hour this machine will produce. I was kind of thinking of purchasing one now, and maybe a second one later to keep up with the demands of a coffee shop.

Answer by A:

Because commercial situations are all very unique, I would suggest calling Mark Jackson in our commercial sales department. He can be reached at 1-888-411-5282, option 1, then option 2.

Helen asked:

What's a good grinder to go with Expobar Brewtus IV

Answer by mjackson:


Certainly there are many choices. I think since you have such a great machine you should consider a grinder that will compliment your selection. I would look at the Baratza Vario. It is an amazing grinder for the price. Next I would consider the Mazzer Mini. If you really want a special grinder look at the Ceado E37. They will all work well. The Baratza would be the most cost effective and the Ceado would be the most professional.

David asked:

I suppose it is best to connect this to a source of reverse osmosis filtered water?

Answer by A:

Any kind of filtered water will help prolong the life of a machine and help prevent against scale build up. I know a lot of people have plumbed machines into RO water systems and had no problems.
