My washer keeps doing this intermittently after a time. I had washer repair people out about a year ago, and the 3rd technician told me the contacts on the board get corroded with time from the slight electrical impulse to signal to the board to shut the door. He resolved it for about a year, like he said, by cleaning the contact on the board with a dollar bill. My machines are stacked and not starting up again. I’ve tried the WD40 trick and it’s not working. I unplugged it overnight and just tried it again, and it didn’t clear because it started clicking trying to shut the door as soon as I plugged it in, not after I pushed “start.” I have it unplugged, again, waiting.
