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

Here's the story. All my appliances except the dryer broke. Yeah. talk about bad luck. First I tried to fix the refrigerator. Replaced both motherboard and inverter board. Now it wakes up but the compressor does not kick in. Need another part. The washer, well I have to pull out the sink to get enough room to pull out the washer to fix it.

I first wanted to get the dishwasher running, before ordering the spring links. So I disassembled the pump / motor assembly to determine the reason the motor would not start.

I cleaned up the bearing and lubricated it with SAE 20W. I also packed felt inside the cavity adjacent to the bearing.... Read more
