Do-It-Yourself Stories from Customers like You Dishwasher started making a grinding noise   Timothy T. • Alpharetta , GA • June 26, 2015

Searched the dishwasher model on ApplianceParts (had used them for a washing machine repair a few years earlier). Was looking for an exploded diagram of the internal parts so I could figure out what might be the problem. There was a video for a motor seal repair kit that seemed to address the bearings which is what I suspected was the culprit. The video started by noting that "you want to replace the motor seal if 1) you have a leak or 2) your dishwasher is making a noise". I watched the... Read more

Push On Retainer Nut
Genuine Whirlpool part
By: Whirlpool
Part Number: WP3400931

The Whirlpool push on retainer nut is an OEM replacement part responsible for securing the heating element in the dishwasher. It is located in the base of the dishwasher's tub to hold the heating element firmly in place. The push-on retainer nut keeps the heating element securely connected to the dishwasher's electrical system while allowing for easy removal and replacement when necessary.

Over time, push on retainer nuts can become loose, worn out, or damaged due to regular use, vibrations, or accidental mishandling. If a retainer nut fails, it can lead to parts becoming unstable or disconnected.

Symptoms of a bad push on retainer nut include:

  • Loose or unstable dishwasher components
  • Parts falling off or becoming misaligned
  • Unusual noises during the wash cycle
  • Difficulty in securing components within the dishwasher

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

Do-It-Yourself Stories from Customers like You Our dishwasher would not start.   Rory D. • Fairfield , CA • May 18, 2020

A bit of searching on the internet narrowed the problem down to either the heating element or the control board. As I am not much of a diagnostician I decided to replace both. Along this same line, I would never have attempted these repairs if it hadn't been for the clear, easy to understand repair videos provided for each part. Further, my decision to do my own repairs was made easier because the prices of the parts was so reasonable. I took my time, reviewed the videos and replaced the... Read more
