Dishwasher Power Cord Strain Relief
Genuine Whirlpool part
By: Whirlpool
Part Number: W11384788

This is a small plastic or rubber fitting that secures the power cord where it enters the dishwasher's junction box or base. It prevents the electrical wiring from being pulled, kinked, or damaged by absorbing tension on the cord. Replace this part if it is cracked or missing, which can leave wiring exposed and vulnerable to damage during installation or use.

Tub Wheel Assembly
Genuine Whirlpool part
By: Whirlpool
Part Number: WPW10505748

The Tub Wheel Assembly is an OEM part for Whirlpool dishwashers. It consists of the wheels and their mounting components that facilitate the smooth gliding of the dishwasher rack in and out of the unit. This assembly is critical for the operation of loading and unloading dishes, ensuring that the racks move smoothly without jamming or causing damage to the dishwasher interior.

Symptoms of a faulty tub wheel assembly include:

  • Difficulty in sliding the dishwasher racks.
  • Racks getting stuck or derailing during movement.
  • Unusual noises when the racks are moved.

The primary causes of wear or damage to the tub wheel assembly can include regular use, excessive load on the racks, or accidental force applied when loading or unloading dishes. These can lead to broken wheels or dislodged fittings, necessitating replacement to maintain functionality.

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 Water leaking from the area proximate to the motor   Nathan S. • Salt Lake City , UT • January 19, 2015

I reviewed the schematic and saw the Volute Seal, and Impeller Seal were the two that were closest my source of water. After watching the video about changing the Impeller/seal I removed the motor, impeller, and volute; I found that the impeller seal was the faulty one in my case. Since I'd ordered the volute and impeller seal kits (as I wasn't sure which it was) I installed both while I had it apart. Runs great, no water - simple to do. The seal changes took about 20 minutes.
