Small black plastic push button on door had broken off. New door switch unit was simple to install from front of washer. Also realized the door seal gasket had been missing since we bought the place, so was constantly needing adjustment. So putting a clamp on fixed that problem as well. Videos online helped make the entire repair take only 15 minutes (need a T20 driver). Also, I ordered Saturday afternoon and parts came by noon on Tuesday (standard shipping was Fedex!). All in all, could not be simpler!
