I have a new Maytag mvwc565fw. The Clean Washer Cycle was interrupted from a power outage and the unit is full of water and the lid is locked (light solidly illuminated). Trying to start any other cycle does nothing. Unplugging does not reset it. I couldn’t even get the diagnostic mode come on.

you need to turn off, unplug, plug back in, turn on, move cycle knob to stop, wait a few minutes, and then select cycle you desire, press start and hold handle firm against door 'till light stops blinking and it should go.

Uh oh! It did it again! This time I had to unplug 6 times for one cycle. Seems to be on the last 2 minutes most of the time. Today my husband is taking the control unit and looking for soldering problems. On Askmehelpdesk.com this man told of taking the bottom panel off and there is a little black latch thingy you pull to open the door lock manually. Also he said that the K2 and K4 relays are usually the problem if it isn't a soldering issue on the connectors. ( On the CCU);. He said one of them is usually burned and to clean it off and then switch it with the other one which carries less voltage, therefore doesn't burn. You can use a pencil eraser to do this. My husband told me they did this in the Army for MOose code contacts. He just told lme the soldeirng looks good on the connectors and is now working on the K2 and K4 relays. If you go to Askmehelpdesk.com/appliances you will see these tips are for the Whirlpool Duet whic is apparently the same machine as our Sears Kenmore H4's. Gosh, I hope this helps someone as it sure is not fun trying to track this problem down. I am glad you got Sears to come out. I will NEVER and I repeat NEVER buy from Sears again! Did I mention I wrote a letter months ago when I was having a hard time getting warranty work done.( Which I never did) that I had written to the pPesident, CFO and the Texas Attorney General for Consulmer Protection Division and never got a response from anyone?

The magnetic switch was stuck due to power outage / contactor are spark connect the contactor stuck together .Magnetic switch to replace.

Resolution:If the washer does not accept inputs from the control panel, follow the Hard Reset steps below to reset the control:

Unplug or turn the circuit breaker off for 30 seconds.

Plug the power cord into the wall outlet or turn the breaker back on and wait 30 seconds.

Press the Pause / Cancel / Stop button twice to clear the display.

Start a short cycle, to check operation of the appliance, by selecting a cycle and pressing and holding the start button until the appliance starts.

Note: If the Hard Reset does not work, there may be an internal failure with the washer, that requires service.

There is a service manual behind the control panel it will show you how to test the door locks. If might have a bad lock solenoid.

It sounds like you need to re programme the
With the machine plugged into the wall and
turned on and the headset turned off this is what
you do.
Push and hold down the start button, while doing that you need to then push and hold down the power button.
Hold them down for about 5 seconds, during
which time you may a series of up to 3 beeps.
Then release the buttons.
Turn the machine off and then on again followed by the start button. Allow the machine to then run the complete cycle.
This should correct your problem, if this doesn't then you may need to then look at replacing the computer panels.
