Float Palnut (Dishwasher)

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

This past Tuesday as I was having my first cup of coffee, my wife says to me, "Would you like to start your day out with some bad news ?". Anyway, she tells me that our 15 year old Maytag dishwasher is "dead". This machine has been a "champ" at it's job, and "momma" has been very happy with it's service. And, it has been working, recently, just as good as the day we first used it. So, I started investigating. As background, I am a retired 68 year old (male) DIY'er. I was an Aviation... Read more

Door latch failure
Will not dispense detergent

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
