  • Note wire positions; transfer connectors one at a time and secure the switch in its bracket

I called and talked to a customer service rep and she helped me troubleshoot the problem and order the correct part. She also sent me the pdf of the repair manual and I followed its instructions to replace the drain solenoid. It was a fairly easy repair. I wasn't sure if I would need the water level control switch, but I ordered it to be on the safe side. Turns out the original is still good. Read more

Do-It-Yourself Stories from Customers like You Problem with detergent cup lid.   John M. • Craig , CO • November 27, 2017

The foam was shot on the detergent cup lid. Hard as a rock. Causing caking problems, dribble down the inside wall of the door and leaving lumps of detergent. Cut the door in half wit aviation snips and pulled out the two halves. Discovered at this point that the spring had gone soft. Bought one ahead of time, so I was set. Put the spring on the left pin, put the spring pin in the door, slipped the door into place (open) and put the right pin in with pliers. Door snaps open now. Read more
