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

Do-It-Yourself Stories from Customers like You Dishwasher started making a grinding noise   Timothy T. • Alpharetta , GA • June 26, 2015

Searched the dishwasher model on ApplianceParts (had used them for a washing machine repair a few years earlier). Was looking for an exploded diagram of the internal parts so I could figure out what might be the problem. There was a video for a motor seal repair kit that seemed to address the bearings which is what I suspected was the culprit. The video started by noting that "you want to replace the motor seal if 1) you have a leak or 2) your dishwasher is making a noise". I watched the... Read more

Do-It-Yourself Stories from Customers like You Heard intermittent grinding noise for maybe five seconds after it switched from fill to wash then later in cycles also   David J. • Appleton , WI • March 15, 2015

Spun each of the three wash arms by hand. All could be made to touch/scrape but the top one was super wabbly. Ordered both the arm and clip. Repair took less than a minute. Used a screwdriver to pry loose one side of the old clip to remove. Aligned the new parts and easily snapped into place. 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

Genuine Whirlpool part
By: Whirlpool
Part Number: WP99002003

This O-ring creates a watertight seal in your dishwasher's wash or drain system, helping prevent leaks and maintain proper water pressure. Replace a brittle, flattened, or damaged ring to restore a reliable, leak-free connection.

  • 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 Rinse agent reservoir was leaking unit wouldn't hold liquid… just ran out as you filled it   Morgan L. • Cumming , GA • August 19, 2014

Ordered the part. Arrived the next day. Took the eleven screws off the door exposing the back of the Soap/Rinse Aid dispenser. Six screws hold it on the inside of the door. Popped off easily. There is a plug that runs from the timer to the dispenser…it's a pain to get off. Use a flat head screw driver. Screwed the new unit in place. Plugged it in. Put the door back together. I accidentally caught the door catch in the door and screwed it together seizing it...so I had to take the top screws off... 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

Bottom

Do-It-Yourself Stories from Customers like You Leaking at the front of the dishwasher and junk on the dishes after washing   Michael R. • Los Angeles , CA • March 08, 2016

Part I ordered was not the problem. The corners of the dishwasher were loaded with garbage, grease and other foodstuffs. I digitally cleaned out the corners, re-seated the door seal and used a cleaner in the machine. Did two courses of cleaning. Also needed to clean the pump screen and top of the pump. Lots of junk there. All of this fixed the leaking and the junk on the dishes. Hardest part was loosening the duct from the top impeller to the pump. Read more

What's included: One inner slide rail (track) Install notes:

  • Disconnect power to the appliance before starting and remove the drawer to access slides
  • Retain and reuse any factory screws/fasteners unless replacements are provided
