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

Sensor
Genuine Whirlpool part
By: Whirlpool
Part Number: W11410464

The Sensor is an OEM replacement part for Whirlpool dishwashers. It detects the level of dirt and food particles in the wash water to help the dishwasher adjust the wash cycle accordingly, providing efficient and thorough cleaning results. It monitors the clarity of the water and determines when additional rinsing or detergent is needed.

Symptoms of a faulty sensor include:

  • Inadequate cleaning performance
  • Dishes remaining dirty or stained after a wash cycle
  • Extended cycle times or the dishwasher not completing the cycle

A bad sensor can occur due to regular usage, buildup of residue or debris, or electronic malfunctions. If you notice issues such as poor cleaning results, dishes not being thoroughly washed, or the dishwasher not completing the cycle, it may be time to replace the sensor with this genuine OEM part.

This OEM part is also compatible with Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and Kenmore models.
