    What companies do you guys use to repair/rebuilt Wasco compass control boards (CPU and invertors).  Name and location of company would help.

    Thanks,

    I have SU series Wascomats and have replaced a dozen inverters (at $800 each).  I'd love to find out if anyone has a repair for these.

    I have a problematic Electrolux / Wascomat inverter displaying a Motor Too Hot Error Code 32. The motor is not hot and the drum moves freely so it is the inverter falsely generating the code.

    I have reached out to a company called El Tech Lab in NJ and will follow up here to let you know how it goes.

    Yes David.  This is the message which has been plaguing me.  Every time I get this message it is only solved with a new inverter.  Let us know if you have success getting these fixed somewhere.  I would appreciate any tips anyone has on this, including any Wascomat/Electrolux people who monitor this forum.

    Mountain Electronics repairs Wasco inverters.

    We used to have 1-2 failures a year, especially during the summer months (voltage spikes/drops from AC kicking on?).  Once we installed a couple of TVSSs, we haven't had a single failure.

    James & Tony,

    When we designed & programmed with off the shelf Hitachi Inverters for our 902-1092 G- force extractors adventure we were extra careful to  make sure there was the ability for air to flow extra good & also with foam at the openings so dust would not accumulate either.  It has been over 7 years now & no "heat" problems like David tipped you off to.

    I'm new to here and really just browsing, but do you have a surge protector to protect the electronics in your equipment?  Does Wascomat say that the CPU / invertor failed due to an electronic spike, or are you just replacing the item(s) and moving on?

    Michael,

    I do think that inverters need to be checked every now and then to make sure they have adequate airflow which is one of the causes of unnecessary failure for these expensive parts.

    On another note....Can someone please tell me why the manufacturers of expensive commercial washers that have expensive inverters do not bother to include surge suppressors integrated into their equipment?

    Seems like a no brainer to me. The laundromat operator should not have to install surge suppressors on their mats simply because they have purchased washers with VFD's.

    Manufacturers....Look at it this way.....What a great selling point that would be in the minds of operators who have been stung by shelling out ridiculous amounts of money for burned out VFD's.

    A nice resettable surge suppressor would boost your sales nicely.

    Good question from Paulie re: manufactures installation instructions seriously lacking for machines with VFD motor inverters.

    A good TVSS should prevent most of these very expensive electronics failure. I am going to install one to protect my newly repaired inverter.

    All of my sincere thanks and appreciation are to the contributors here on this forum who add value by sharing their knowledge and experience.

    For inverter repair I looked into El Tech Lab however their website and email communication did not work and after three days I got a phone message from them. So, instead I sent the Electrolux VFD to Mountain Electronics and it came back in about three weeks. Unfortunately it was not fixed and the Error 32 reappeared on first try. This is worrisome because presumably something was done to the VFD but it did not address the problem. I sent it back and they reassured me that a higher level tech would work to fix the issue.

    Electronics repair is a funny thing. What other things do we have repaired without being informed what was done? Certainly not your car or medical care.

    The Mountain Electronics website works well and it allows for easy UPS label printing to their shop. Their phone manners were excellent and I have high hopes that I can get it back in working condition soon.

    I can vouch for Mountain Electronics.  Fabulous service, very responsive and great website with free shipping.  I've never sent them an inverter, but probably ten Dexter dryer computer boards for new relays.  I tried to do the relay myself once, it looks easy, but sort of like changing the screen on an iPad myself once, I now know that there are things left to professionals.

    I hope they can fix your inverter.  The only thing I've sent them that they couldn't fix was a part that was blocked in epoxy (who does that?), they couldn't get to the part to fix it.  Good people, one of my favorite vendors.
