I love my Expobar Office Lever. What a great machine! Thanks for sharing!
Hi N, Thanks for the comment. Is yours a rebuilt machine? I consider the Office Lever to be one of the best values in home espresso!
It is not. Bought if from y'all brand new back in March (along with a Ceado E6Pv2). It is such a pleasure to use. The espresso it makes is heavenly. and it can steam all day long. Only thing that took me a while to figure out was the steam wand since it's single hole, so to get good microfoam the tip needs to be almost all the way out vs traditional wands to get air pulled into the milk.
That's awesome and nice Ceado grinder - it's got to help make the espresso heavenly! Thanks for the feedback.
Thanks Todd for the video and answering my questions. I purchased a refurbished Office Lever several years ago and it has served me faithfully with reqular maintenance. Two years ago the boiler heating element burnt out and I replaced it myself. Although the pump was working fine, I decided it was probably as old as the heating element so I replaced it at the same time. I flush my Office Lever everyday and do a thorough flushing with Cafiza detergent every two weeks. I run on filtered / softened water and I replace the softner medium in the reservoir softener every 3 months. I just rebuilt my brew group last month and there very little evidence of scale any where in the group. Some of the vaIve seals were pretty worn so I replaced all the seals and gaskets. I would not have any fear of purchasing a refurbished machine from Todd and company in the future.
Hi JB, Thanks for sharing your experience with the refurbed Office Lever! Sounds like you are taking good care of your faithful servant!
Even though this is a two year old video, I know how great y'all are at getting back to comments! So I figured I'll share a fun story. For the last 8 years, I have always had access to a semi-automatic espresso machine at my office; up until the pandemic. I had been saving up a little pile of money to get an ECM Slim and a grinder for home when my industry shut down like many in the second week of March. I was thankful to have that espresso piggy bank as my unemployment insurance took 9 weeks to show up! Thankfully that is all sorted, and as luck would have it after telling a friend about spending my coffee fund on my mortgage & groceries, they gifted me a Expobar Office Leva (rotary). It had been professionally maintained, and I can see some parts are quite new (as opposed to 10 years old), but I know there are two concerns:
First, it has been stored for two-ish years without having been properly drained. Thankfully Whole Latte Love has a great video on how to drain it. I'm getting a hose to connect it this afternoon to drain it, then run a bunch of cleaning cycles. is there anything specific to watch out for having been improperly stored for so long? I don't believe it was stored in a location where freezing would have been possible, but I can't say for certain.
Second, while I know it regularly got maintenance from a professional local shop, I also know that for 8 years it was on a water supply with quite-hard water and no softener. I know that descaling a neglected system can be a bad idea, but my home has a whole house softener... so is running soft water through some pretty calcified parts going to lead to clogged orifices and screens? I know shipping would be a ton, but do you offer the full re-build service that you showcase on this video as a service for owners? I am a very handy mechanically incline person and thankfully your site has all the parts available to build one from scratch practically. If Todd and Bob are still at it, maybe just talking through a shopping cart with them is best? (Which is already sitting over a grand, lol)
Anyway, I really want to thank your whole team for having such an exhaustive library of videos blog posts etc. It's kept me sane while waiting for the unemployment money to show up. And, while I was sad to not pull the trigger on that ECM and grinder, the universe seems to have found a way to make me a paying customer yet.
Cheers,
-Zak
Hi Zak, What an interesting story - thanks for sharing! You have a great and generous friend. I'll do my best to help you out.
1. Hopefully no freezing with water inside the boiler! That could cause a lot of issues. If there was water inside and it did not freeze that water may be really gross coming out. Hopefully machine runs and you can do some flushing. If the machine were in the shop here it would likely get a full rebuild.
2. Descaling a neglected system can cause problems. But if you are mechanically inclined you may be able to deal with them. Solenoid valves would be a big one. I'd also check the E61 group - our tech manager shows how to do that in this video: th-cam.com/video/4H57QSEMDhs/w-d-xo.html
Also check our support wiki for your machine here. Manuals, diagrams, maintenance info and more: wiki.wholelattelove.com/Expobar_Brewtus_IV/diagrams_and_manuals
We do offer full rebuild. You'd need to contact our tech support at 585-924-7170 for info on that. If nothing else they can help walk you through any needed parts. When we do the rebuilds here the machine is generally disassembled for service. So boilers are removed and descaled outside the machine etc. If the machine was regularly serviced in the past perhaps it's not too bad?
Good luck with your project and we're happy to know we helped keep you sane!

@@Wholelattelovepage I knew you wouldn't disappoint with the quick (and thorough!) reply Marc. Thankfully it all seems to fire up, but since picking it up yesterday, I have not let it be on for more than 20 seconds until I have a hose to go into a fresh water supply AND I'm ready to deal with scalding hot, likely very gross water. Once I attempt the first flush, I'll pop open the mushroom valve, and if there isn't much calcium build up there I'll take that as a good sign the other internals were well looked after. If not, it's great to know that rebuild service is an option. Hopefully by the end of the week I'll be tagging you with a first shot photo on instagram!
Hi guys, love your videos,Q. Do you have a video of heater element on Expobar Minore IV/Brewtus
Hi NH, Well thanks for the comment. Unfortunately nothing else on the element.
I can recommend the purchase of a rebuilt/refurbished machine from WLL. I bought a refurbished super automatic from WLL and it worked perfectly for years.
David thanks for the comment! Happy to hear your machine is doing well 5 years in!
Great videos. Very informative. Appreciate everything you guys do...
I have a Brewtus 2 that I’m currently doing work on. The brew temperature overheats. It just keeps going up until I have to shut it off (250+), or steam pours out of head. Could you point me in right direction?
Hi Ray, If you are in the US you can speak to our tech support by phone and they should be able to help point you in the right direction. Contact info: www.wholelattelove.com/pages/contact-us
What size wires did you use to replace bad wires?
Hi CW, Match gauge of new wires to that of old.
Hi Todd! How did you begin to repair/rebuild machine ? Where did you learn all that? Thanks,
Hi Brisson, Todd has been working on machines for about 20 years. Prior to that his background was in HVAC system installation and repair. Many common elements like electrical, plumbing, pressure carrying components from that experience which transferred into the espresso machine world.
nice
Could you tell me please the weight of both boilers? One is designed to hold 1.6 bar, the other is for higher preassure - 9 bar. I think the second should be much heavy.
Hi m, Thanks for the question. Not aware of any boilers which go to 9bar - that would be a crazy high temp! The steam boilers in Expobar machines do reach about 1.6 bar. Brew boilers in dual boiler machines generally run under 1 bar. Boilers are constructed to handle the pressure and have safety relief valves if for some reason boilers exceed their rated pressures. Hope that helps! Marc
@@Wholelattelovepage Sorry for not understanding, but I have a scheme of 2-boiler coffeemachine in which it is said that the e61 group and the boiler are connected, there are not valves between them. The pump produces 9 bar into the boiler, the boiler heats this water to 92 degrees and transfer it to the group. So there's 9 bars in the boiler, too.
Where does these machines come from? Are they returns? Do you get them from the trash bin?
Hi e, Thanks for the question. So on the DL, I know this guy down in Jersey. He knows this other guy. Let's call him Tony. Anyway "Tony" is big in the trash biz. When his crew finds a machine on the "curb" they send it up to us and bada bing we rebuild it good as new! Maybe a scratch here and there but otherwise all critical wear components replaced, fully tested and 1yr parts and labor warranty. Okay, so only the last sentence is true. These machines actually come from a variety of "Tony" free sources. Some common ones: returns, demos, loaners, exchanged under warranty, in-house use, repair and customer opted for a new machine.
Where is the flow restrictor installed in the thermosiphon line, on the boiler side or the brew group side?
Hi JB, thanks for the question. The flow restrictor in Expobar HX boiler machines is located in the tube running from top of boiler to top of group. Depending on age of the machine it can be located at either the boiler end or brew group end. It does not make any difference which end. Hope that helps!
Todd
@@Wholelattelovepage hey Todd thanks for the quick reply. I have an older model Lever that has only the boiler pressure gauge. I pulled the top brew group line off and there is nothing in the brew group side, but the boiler side has what appears to be a blacck disc with about a 3mm hole in the center. I assume that is the restrictor?
Todd, also after removing the line and reinstalling it, it takes my machine over a minute to reach brew pressure with a portafilter gauge installed in the brew group. The pump is moving water but takes way to long to hit 9bar. Worked fine before pulling the upper boiler line off. Any ideas what the problem is?
That would be the restrictor!
Can't be sure without machine in front of me but sounds like an obstruction is limiting flow to the group and therefore causing pressure to build slowly. In a case like this when it worked fine before and now it does not the question is what changed? If only thing was removal and re-install of pipe given the age of the machine my guess is dislodged material is causing obstruction. I would remove the mushroom valve from the group and inspect/clean. Info on that and more in our support wiki for the Expobar Lever found here: wiki.wholelattelove.com/Expobar_Office_Lever/troubleshooting#My_brew_pressure_is_low
Start at section in wiki titled: I Have No Water Flow At All From The Group
There's a video there showing How To Clean E61 Brew Group Mushroom, Jet and Top Valve
Hope that helps!
Will you rebuild a customers machine?
Hi AU, Thanks for the question. Yes, we do offer that service. Also know at the moment we are booking out into the future longer than normal for repairs, etc. But you can contact here for more detailed info: www.wholelattelove.com/pages/contact-us
