Dishwasher Rack Roller
Genuine Whirlpool part
By: Whirlpool
Part Number: WP99003147

Replacement roller wheel for dishwasher racks. Clips onto the rack assembly to enable smooth sliding. Replace when cracked, broken, or worn from use.

Do-It-Yourself Stories from Customers like You The wheel cracked and the rack was falling out of the sliding track   Chris W. • La Crescenta , CA • July 16, 2014

The Dishwasher Rack Roller was a perfect fit. It took longer to find the part (because I kept typing in wheel) than it took to fix the issue. The old part snapped off and the new part clipped right on. I bought all four rollers even though I only needed one because I'm sure the next one will crack soon. Thanks for the great service.

Water Level Switch (Float)
Genuine Whirlpool part
By: Whirlpool
Part Number: WP99002560

This water level switch senses the dishwasher's tub float and controls the water inlet. Replacing a worn switch restores correct filling, helping prevent overfilling or dry cycles that can reduce cleaning performance. What it does:

  • Monitors the float position to open/close the fill circuit at the proper water level
  • Common symptoms: dishwasher won't fill or stops filling too soon
  • May also cause continuous filling/overfill if contacts are stuck closed
  • Intermittent operation can leave the tub underfilled and washing performance poor

What's included:

  • 1 water level (float) switch

Install notes:

  • Disconnect power and shut off the water supply before servicing
  • Remove the toe/kick panel to access the switch near the float assembly under the tub
  • Note wire positions; transfer connectors one at a time and secure the switch in its bracket
  • The float moves freely and actuates the switch before reassembly and testing

This part fixes the following symptoms
  • Will not drain
  • Won't start
  • Will not fill with water

Do-It-Yourself Stories from Customers like You Dishwasher wouldn't drain   Ken S. • Columbus , OH • August 18, 2018

I called and talked to a customer service rep and she helped me troubleshoot the problem and order the correct part. She also sent me the pdf of the repair manual and I followed its instructions to replace the drain solenoid. It was a fairly easy repair. I wasn't sure if I would need the water level control switch, but I ordered it to be on the safe side. Turns out the original is still good. Read more

Do-It-Yourself Stories from Customers like You Flappers on docking station were worn out and/or missing also the pump filter fabric was torn so a new pump filter was installed as well   Gregory P. • Mansfield , OH • January 01, 2017

Dishes were 'gritty' with an almost invisible coating of specks smaller than grains of salt. Prior to ordering parts, I had to determine which part(s) needed replaced and which could benefit from a good cleaning. After viewing Appliance Parts Pros YouTube Videos, I removed the Main Manifold (snaps right off) including the Top Spray Arm. I discovered the Flappers of the Docking Station (AP6009888) were worn out and/or missing. I removed the Docking Station simply by popping the old one off... Read more
