  • Provides a watertight seal between mating parts such as pump housings, fittings, or hose joints
  • Helps stop drips and seepage caused by a worn or deformed seal
  • 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
  • Clean the groove and mating surfaces; lightly moisten or use a manufacturer-approved lubricant to help the ring seat without pinching
  • Seat evenly, reassemble without overtightening, and run a short test cycle to check for leaks

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

Do-It-Yourself Stories from Customers like You Dishwasher would fill then shut off when restarted it would try to fill again overflowing   Robert J. • Schererville , IN • July 02, 2016

I replaced the float switch. It was an easy enough repair. I didn't have to remove the dishwasher to do the work. The part is accessible from behind the front skirt.The only problem was there is not a lot of space to work in. Getting the fastener off and on requires a stubby nut driver. I used a flexible extension instead. I had to feel for the nut as the bottom of the door blocked my view. A ten minute job and the dishwasher is back in service (for half the cost of my local parts place) While... Read more

Do-It-Yourself Stories from Customers like You Dishwasher locked up   Joseph B. • Grants Pass , OR • January 07, 2018

Early last year our dishwasher stopped running, and we did things the old fashioned way by standing in front of the sink ourselves. When Thanksgiving and Christmas came back to back with extended family in the home my wife said that she wanted her dishwasher back. After doing some reading and some simple diagnostic stuff, I contacted one of your staff through Chat, affirmed a few things, and ordered the right Control Board. The installation literally took less than 10 minutes, but my wife was... Read more

Do-It-Yourself Stories from Customers like You Our dishwasher was not cleaning the dishes no water pressure it seemed   Melissa F. • Falls Church , VA • June 06, 2015

I looked in the bottom of the dishwasher and saw that the center piece of the water wheel had somehow come loose. That center piece was lodged under the heating element and was now somewhat beaten and melted. We looked on line for an illustrated parts breakdown and found it on Appliance Parts Pros website. The diagram was so clear and straight forward that it was easy to see the part that we needed and another part (when we looked) we also found missing. Well, 3 days later the parts came in...

Do-It-Yourself Stories from Customers like You Would not drain all the way   Michael R. • Elkridge , MD • March 15, 2014

The new drain pump solved the problem and was also quieter than the one it replaced. I saw that many people removed the dishwasher from under the counter to make the repair. Not sure if it was easier, but I was able to do the repair through the kick plate opening. This saved me from having to get the unit positioned back in the exact same place, leveled, and all the sound insulation trim re-installed. I did notice my leveling feet were extended more than half way. This may have made it... Read more
