My front load Speed Queen (2 years old) is dead. Will not power up. Nothing on “resetting it” in the owners manual. Plugging and unplugging does nothing. Digital controls. Any suggestions? Everyone is closed till after Christmas.
 
I don’t know anything about the speed queen front loaders, but twice this year on service calls for washers I found the duplex receptacle that the machine was plugged into to be faulty. It had power but the receptacle was worn out and not making good connection. It may not be the solution, but it’s easy to try. I would either plug something known to work into the receptacle or temporarily run a cord from another one. Good luck!

You’re under warranty, call up your dealer and/nearest authorized SQ repair company.
Mine did this multiple times, each time it required AT LEAST a new main computer lol.
Make sure they use a fresh new replacement part direct from SQ if it is the computer. The older the worser for that part.
Call ASAP, make sure the tech knows the front load models, they usually are familiar with the top load machines, vastly more common and a completely different animal.
 
Long term updates

While I tend to be harsh on SQ, it would be really interesting to see if the new parts are any different as in if they will fail again in 2 years or if they do live up to their claims.
I mean everybody can make mistakes from time to time, and if its a common issue it should be easy to track down and resolve for future parts.

So if anything ever comes up make sure to post again with a short service history!
 
>> New circuit board ordered. $600. Under warranty. Got the updated part number for latest—thanks for the tip.

$600... oof.

Is the failure obvious on the board? (burned components, etc?)
 
Dead SQ FL Washer

All the larger capacity SQ FL washers had a component on the main motor board that failed and necessitated replacement of the motor board. This affects machines that were built from about two to four years ago, this is the reason that I asked the poster for the serial # of his failed machine so I could tell if this was the problem.

 

We have replaced more than 40 of these boards, we have never had a 2nd failure and none in machines built in the last approximately last two years. These are incredibly good heavily built washers, this board problem is in fact the only problem we have ever had with one of these newer SQ FL washers that was a result of manufacturing quality control.

 

Hi Henrik, you can go ahead and make cracks about SQ washers [ something you have no direct experience with ] and I will resist making cracks about your decision to buy used VWs and all their problems, something our family has lots of experience with, LOL

Electrolytic caps are the MOST failure prone electronic-electrical components.However in one of our transmitters-HV PSM power supplies-these are now over 30yrs old.there are four 320Uf 600VDC Mallory caps that have lasted over 30yrs!None of them have blown yet.The most reliable electrolytic caps I have seen.We keep the supplies energized-the fewer charge-discharge cycles the better!Each of the 32 power supplies develops 900VDC and they are in series to modulate and supply plate HV to the PA tube.the current is 30-60A.the caps are mounted on large phenalic panels inside the modulator stages-replacing them would be a nightmare!!!!You would have to take all that apart!!!
 
Electrolytic caps are almost certainly NOT the failure here. While I do agree that poor quality capacitors are a plague on electronics, they aren't the cause of early failures like these.
 
Surge protector

Should I plug my 1 year old speed queen front load washer into a sole surge protector to protect it?
 
Faialed Motor Boards On SQ FL Washers

The board builder used a component that did not live up to the quality specified and had a very early failure.

 

A surge protector would not help and is unnecessary as there is one built into this board, these boards did not fail because of voltage surges.

If the control board that was replaced was the motor control board, I'll hazard a guess and say it was a failed NTC thermistor or solder joint or even circuit board trace.

Most motor drives I have seen fail is usually caused by overheated thermistors and the connection to them.
 
"Pray tell, what is this mystery component? "

Perhaps it was one of those 4 or 8-legged transistor diode packages, which seem to get superseded by versions a tad more robust?
 
For your viewing pleasure. The dead board. The washer does seem to spin better now may be my imagination now. Not so quick to chicken out on heavy loads.

I'd love to see someone diagnose what's wrong with the board, I bet someone could figure it out pretty quick with little more than the diode check function on a new meter. Perhaps a shorted transistor(one of the mosfets that controls it).
 
Hi Richard, Good to see you posting, I would be glad to send you a bad motor board [ or 5 or 10 even ] if you want to try fixing it, but I suspect it needs a fairly sophisticated part, I tried to get Core-Centrics to fix one for us and even they said they did not have the parts and expertise to do it.

danmantn, can you pop the PCB out and take pics of the back? I have never dealt with Speed Queen boards but a common failure point on boards like this are the solder connections of the connectors
