I was recently here and with your help I managed to get this washer repaired by replacing the control board. It worked fine for about a month but now it stopped working with new symptoms.
Now when I set it to wash and pull the knob the door lock light will turn on but no activity comes from the washer. The door is not locked despite the door lock light on. I thought it might not be sensing the incoming water pressure so I changed the water temp setting from cold to hot figuring that maybe the incoming cold water sensor was bad but the result was the same. I also changed the main control board to the old one just in case the new one went bad but no change.
My tech head is telling me the control board is not happy with some sensor or condition and it will not allow the washer to start.
Is there any test I can do to figure out what part is bad?
I would be looking closer at the door locking mechanism. Fairly common failure item on these machines. Common enough, our company carries this part on the truck. Part number: AP4455026
