Bravos washer dead

[RAH52]

Went on a MVWB700VQ0 maytag bravos washer(like the expensive whirlpool cabrio with direct drive motor) thats totally dead .Customer said the last time she used it the display was dim and the thing played its end of cycle tune at random times during the cycle .I was unable to get it into diagnostics to look for fault codes and the tech sheet says if trying a new user interface doesn't help try a new machine /motor board .Its an expensive proposition if your wrong .Has anyone had this type of issue ? Also have you had any complaints of clothes tangling in these machines .

Completely dead..............First thing I do is see if the control is getting 120 volts.  If it is,   and you said customer said the display was going dim at times,   I would suspect the control board.    Unfortunately, with these machines,  on a problem like this you have to guess.   I had one that was dead and it was the control board,   but I wasn't told that the display was dim right before.    Hopefully,  someone else had the exact same problem.    Good Luck

Control board is getting 120v ,your right wedgeman it is a guess ,potentially could be user interface but on the other hand control board could be giving me issues .I usually guess wrong LOL.

One easy way to rule out the UI is to disconnect it from the main control with the power disconnected. Then plug it back into the wall. If the control cycles the water valves, it's good. If it still does nothing, replace the main control.

So what your saying Lowsl2 is the valves should come on briefly with the UI disconnected when I plug unit in ?

That's good to know, Low.   I didn't know that.    How long do valves cycle on?

[LowSL2]

They cycle one after the other. Takes 5 to 10 seconds.

One clarification, Low.  You said

"One easy way to rule out the UI is to disconnect it from the main control with the power disconnected. Then plug it back into the wall. If the control cycles the water valves, it's good. If it still does nothing, replace the main control."

So,  If control cycles water valves,  is UI bad?  You said it's good.   If not,  replace main control.  How do you know if UI is bad,  vavles cycle or not?

Thanks, Low.

If the valves cycle when you remove the UI cable and power it back on, it usually means the UI is faulty. If nothing happens, the control is faulty. I'm sure there are instances when the UI and control are both faulty, but that doesn't happen often (to me at least).

Update on my bravos washer call ,pulled the plug disconnected the UI and plugged unit back in the valves did not cycle .I was going to try a control board but opted to try a UI first .That solved my problem .Lucky guess!

Some days I could really use a little luck. Good job.
