I suspect that the motor relay on the board is stuck on. You could try gently tapping on it to see if it opens again. Probably going to need a new relay or a new board.
Not knowing much about electronics can you please advise which column and row the relay would be in that picture.
Also, is that control board picture a generic one or is that one specific for my model? If that is for my modl do you happen to have the part number for it?
So the machine will keep tumbling always unless you unplug it or keep the door open?
Sounds like the motor start relay on the main control board is stuck in the closed position.
