This small check ball sits inside the dishwasher's drain pump or water inlet valve and acts as a one-way valve to prevent water from flowing backward through the system.

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.

• Helps stop leaks and reduces chance of hose slip-off under pressure
• Commonly used on water, drain, and vent hoses where space is limited
• Simple, spring-action design keeps consistent tension as hoses expand/contract

• Disconnect power and shut off water supply before servicing appliance
• Use pliers to expand the clamp, slide into position, then release to seat it
