I replaced the mcu because it was bad. It caused the circuit breaker to trip mid cycle. Now the washer cycles seem to be off.

Hello and welcome to just answer my name is ***** ***** I will be the one to assist you. What exactly is happening?

Customer: replied 9 months ago.
When I was washing close, the house circuit breaker tripped. After further investigation, the MCU in the washer was burned. I replaced the MCU but now the wash cycles seem to be off. When I run the diagnostics test, everything runs as expected.
Expert:  Webb-Guy replied 9 months ago.

Ok now what do you mean by off? Running to long or not finishing cycles?

Customer: replied 9 months ago.
It never goes into full high speed spin cycle. After washing a load today, it appears the cycles to be 1 step behind. For example, when it should be draining, its rinsing. So when its time for the finial spin, it goes to done.

Like the washer is picking up where it left off when the MCU blew.
Expert:  Webb-Guy replied 9 months ago.

Ok now when you say you replaced the MCU was it the main control board or the motor control board you replaced?

Customer: replied 9 months ago.
Motor control board. It had a burned trace.
Customer: replied 9 months ago.
The one at the bottom of the washer.
Customer: replied 9 months ago.
is there a way to reset the washer?
Expert:  Webb-Guy replied 9 months ago.

Well the only reset is to unplug it for up to 5 minutes and then plugging it back in. It should reset it that way. If that does not work I think the problem is with your main control board itself. When the motor control went bad it triggered the main control board as well.

This has your timer and everything in there.

I hope you have found this information helpful and would be willing to rate with 5 stars at the top so I am credited for my time. Rating does not stop you from getting back to me in the event you need me.

The link you sent is not the main control board for my washer. I've already pulled it and inspected it so I know what it looks like.
Customer: replied 9 months ago.
Even though it passes the full diagnostics test, you suspect the main control board?
Expert:  Webb-Guy replied 9 months ago.

Well if things are not finishing like they should and cycles are not reading correctly it is the only logical explanation.

Expert:  Webb-Guy replied 9 months ago.

I noticed that your question was still open so I wanted to follow up with you to see how its going?

Customer: replied 8 months ago.
I replaced the main controller board and have the same issues. The final spin cycle is still slow but in diagnostic mode it goes high speed and everything passes.
