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.

Switch Holder (Mounting Bracket)
Genuine Whirlpool part
By: Whirlpool
Part Number: WP99002240

This switch holder secures a small appliance switch or actuator in the correct position so the control can detect and respond reliably. Replacing a cracked or broken holder restores consistent switch alignment and helps prevent intermittent operation. What it does:

  • Holds the switch or actuator steady in the correct position for reliable electrical contact and activation
  • Keeps the switch aligned so buttons, door/lid actions, or control functions register properly
  • Common symptom: appliance function won't engage or is intermittent when the switch is loose or the holder is damaged
  • Prevents further wear on the switch by keeping it from shifting or rubbing against surrounding parts
What's included: One switch holder. Install notes:
  • Disconnect power (unplug or shut off breaker) before servicing the appliance
  • Remove the control panel or access panel to reach the holder; keep small clips and screws organized
  • Inspect the switch and actuator for damage while replacing the holder; replace any damaged mating parts

Do-It-Yourself Stories from Customers like You Upper spray arm fell off!   Grant I. • Lombard , IL • March 14, 2017

Found the retaining clip on the parts list. Watched the videos to figure out how the upper arm attaches. Tried cleaning out the terribly clogged upper arm. Then looked at the lower wash arm--WOW! Talk about ugly clogs! Watched second video to see how that lower arm comes off. Got the lower arm off and realized all the gunk I was able to poke out of the holes would just come back, so replaced both spray arms. YES, the upper arm includes the retaining clip!!
