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
