I took the motor apart and discovered that the lower bearing ( a sleeve type bearing) was dry and dirty, and was the culprit for the motor seizing. I cleaned up the bearing and lubricated it with SAE 20W. I also packed felt inside the cavity adjacent to the bearing.... Read more

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

Vent
Genuine Whirlpool part
By: Whirlpool
Part Number: W11414073

The Vent is an OEM component specifically designed for Whirlpool dishwashers. As part of the outer tub assembly, it covers and protects the vent opening area located near the bottom of the dishwasher tub.

The vent cover is responsible for regulating airflow and drainage, allowing moisture to escape while preventing food soils and residue from blocking the vent path. It is a key part of the drying performance of the dishwasher. 

Symptoms of a faulty vent cover include:

  • Excess moisture builds up inside the bottom of the tub  
  • Mold or mildew growth near the vent area
  • Blocked or clogged ventilation that reduces airflow

This Whirlpool OEM vent cover replacement is also compatible with Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and select Kenmore dishwasher models.
