Do-It-Yourself Stories from Customers like You Horrible and loud noise when motor/pump was running   Scott S. • Frisco , TX • November 11, 2014

I was able to pull the entire basket/pump/motor assembly out from inside the tub I did not pull the DW out of the cabinet. I did not remove/disconnect the water line or even have to disconnect/cut power. I only removed the drain tube and drain pump. The rest came out from inside the tub. Much easier than I anticipated. There are some videos that demonstrate how to do this. I took my time and cleaned everything once I had it all out. 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

What's included: 1 tub wheel Install notes:
