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

Do-It-Yourself Stories from Customers like You Broken "impeller assembly"   Michael P. • Carriere , MS • September 26, 2016

The initial problem was just a simple blockage on the filter screen...until I dropped a screw. So, I had to take the rest of the insides apart to retrieve it. The original impeller would not come off easily, so I tried to pry it off. Naturally, that caused the threaded portion to break. The new impeller went on much more easily than the old one came off, and the dishwasher is back in action. Simple repair; there's really not much to the inside of this thing. 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

Appeared to be two problems: the latch was worn and one of the pins that slid in a guide on the actuator located in the inner panel had broke off. Detergent lid spring and pin appeared to be OK but decided to replace since I was aready working on it.
