  • Common symptoms: water under the unit, moisture around pump/tubing connections, or leaks after reassembly
  • Replace if the old ring is cracked, cut, flattened, or hardened
What's included: 1 O-ring Install notes:
  • Disconnect power and turn off the water supply before servicing
  • Place a towel or shallow pan to catch residual water

I looked in the bottom of the dishwasher and saw that the center piece of the water wheel had somehow come loose.

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

Replaced the heater element, per the video. Also had to connect a new terminal to one of the heater element wires.
