Screw (8-32 Thread)
Genuine Whirlpool part
By: Whirlpool
Part Number: WP3400892

Replacement 8-32-thread screw used to secure panels, brackets and small components in compatible household appliances. Restores missing or stripped fasteners so panels and parts stay firmly attached during normal use. What it does:

  • Secures trim, panels, brackets and control housings to maintain proper assembly.
  • Replaces missing or damaged screws that can cause rattling, loose panels or misaligned components.
  • Fits locations that require an 8-32 threaded fastener; correct length and head style for your application.
  • Helps restore stable, vibration-free operation when worn or stripped fasteners are replaced.
What's included: One screw. Install notes:
  • Disconnect power and water before servicing; wear eye protection and gloves.
  • Use the correct screwdriver or driver bit to avoid stripping the screw head.
  • Do not overtighten—turn until snug and secure to avoid damaging threads or surrounding parts.
  • If the original used a washer or nut, reuse or replace as needed and the screw length and head type match the original.

Genuine Whirlpool part
By: Whirlpool
Part Number: WP8572611

This vent assembly allows hot, moist air to escape from the dishwasher tub during the drying cycle, helping dishes dry efficiently. It is typically located on the inner door panel and may include a duct and flap mechanism. Replace this assembly if dishes remain wet after the drying cycle, if you notice moisture or steam leaking from around the door, or if the vent flap is stuck or damaged.

Do-It-Yourself Stories from Customers like You Excess steam release caused leaking down the front of the dishwasher   John F. • Chester , NJ • August 02, 2015

Replaced Air Vent (+gasket). (Based on some googled descriptions of how.) Took out several screws in the vicinity of the vent on upper left of door. These are specialized torx screw heads. Released inner panel enough for air vent to slide out. It is held to the panel by the louvered round cover. Twist the cover to the left to remove it and the Air Vent comes loose. I tested the resistance of the old Air Vent and found it to be ~18 ohms. I had found on one site that it should be between 6 and... Read more

Do-It-Yourself Stories from Customers like You Dishwasher started making a grinding noise   Timothy T. • Alpharetta , GA • June 26, 2015

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

Do-It-Yourself Stories from Customers like You Kitchenaid new proscrub dishwasher only comes with one fold down cup shelf   Mary S. • Chester , MD • September 06, 2015

Bought another fold down cup-shelf to double capacity. Relatively easy to install. My Sears Kenmore dishwasher came equipped with two fold down cup holders, one on the right and one on the left. I use these daily to increase the storage capacity in my dishwasher. I was frustrated when my Kitchenaid dishwasher in my new vacation home only came with one, so bought a second cup holder unit and snapped it in place.
