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.
