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

Float Palnut (Dishwasher)
Genuine Whirlpool part
By: Whirlpool
Part Number: WP911265

This float palnut is a push-on retainer that secures the dishwasher's water-level float to its stem. Keeping the float anchored helps the overfill protection work properly, supporting correct fill levels and helping prevent leaks from overfilling. What it does:

  • Holds the float in position so it can move freely with water level changes
  • Helps the float reliably actuate the overfill/float switch
  • Replace if cracked, loose, or missing
  • Typical symptoms include a loose or wobbly float, the float popping off, erratic filling, overfilling, or leaks near the float area
What's included:
  • One float palnut
Install notes:
  • Disconnect power and turn off water supply before servicing
  • Remove the lower rack to access the float assembly
  • Remove the old retainer; press the new palnut squarely onto the float stem until snug
  • The float moves freely up and down before reassembling

Do-It-Yourself Stories from Customers like You Runs but will not fill with water   Michael K. • Las Vegas , NV • January 25, 2020

I first installed the inlet pump with no results. I then ordered a Control Switch and Float and Nut. This fixed the problem. Everything comes out so clean. I also replaced the filter which allowed me to clean debris around old filter. It is also easier to replace all these parts with the dishwasher pulled out and tilted on its side. I had to pull mine out to unplug power to the dishwasher. Read more

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 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
