W10524920 Dishwasher Rinse Aid Dispenser Cap

Key Features

  • Airtight Seal: Features a high-quality rubber gasket designed to prevent rinse aid from leaking into the dishwasher tub prematurely, ensuring it is only released during the final rinse cycle.
  • Ergonomic Grip: The top surface is designed with a textured ridge or slot, making it easy to twist open and closed even with wet hands.
  • Chemical Resistance: Manufactured from food-grade, corrosion-resistant plastic that withstands constant exposure to rinse aid chemicals and high wash temperatures.
  • Snap-Lock Security: Engineered with precision locking tabs on the underside to ensure the cap remains seated during high-pressure spray cycles.

Compatibility & Fitment

This rinse aid cap fits the dispenser assembly of most modern Whirlpool-built dishwashers. Key compatible brands and series include:

  • KitchenAid: Fits KDT, KDF, KUDE, and KUDL series (e.g., KDTM354ESS, KDTE104ESS).
  • Whirlpool: Compatible with WDT, WDF, and WDTA series (e.g., WDT720PADM, WDT970SAHZ).
  • Maytag: Fits MDB series models (e.g., MDB4949SDH, MDB8959SFZ).
  • Jenn-Air & Kenmore: Compatible with 665 series (Sears/Kenmore) and high-end Jenn-Air units utilizing the W10524920 dispenser style.

When to Replace

  • Missing Cap: The original cap has been lost or accidentally thrown away with food scraps.
  • Leaking Rinse Aid: You notice the rinse aid reservoir empties much faster than usual, or there are blue streaks on the inside of the door.
  • Broken Tabs: The plastic locking "ears" on the bottom of the cap have snapped off, preventing it from staying locked in the dispenser.
  • Damaged Gasket: The internal rubber seal is cracked, swollen, or missing, allowing water to enter the rinse aid chamber.
  • Stripped Slot: The top adjustment or removal slot is rounded out, making it impossible to turn the cap with a coin or thumb.

Installation Tips

  • Cleaning: Before installing the new cap, wipe away any dried rinse aid residue around the dispenser opening to ensure a flush seal.
  • Alignment: Align the tabs on the bottom of the cap with the notches in the dispenser housing.
  • Locking: Insert the cap and turn it approximately 1/4 turn clockwise until it stops or the arrow on the cap aligns with the "Lock" icon on the dispenser.
  • Do Not Overtighten: The cap only needs to be snug to seal; using pliers or excessive force can crack the plastic dispenser housing.
  • Maintenance: If you struggle to turn the cap, a very small drop of vegetable oil on the rubber gasket can help it glide into place more easily.

FAQs

This cap is designed for use with a wide range of dishwashers manufactured by Whirlpool, KitchenAid, and Kenmore. It is a direct replacement for units utilizing the W10524920 dispenser assembly.
This part replaces W10524920, W10482848, WPW10524920, PS11755939, AP6022605, PS6883851, and WPW10304408.
You should consider replacing the cap if the original is cracked, the rubber seal has deteriorated, or the cap no longer clicks securely into the closed position. A loose or damaged cap can cause rinse aid to leak into the dishwasher tub, leading to excessive sudsing or poor drying performance.
No tools are required. This is a simple hand-installation; you simply align the cap with the dispenser opening and twist it into place until it locks.
The constant exposure to high-heat drying cycles and harsh dishwasher detergents can cause the plastic to become brittle and the integrated rubber gasket to lose its elasticity. Once the seal is compromised, the cap will no longer prevent rinse aid from leaking out during the wash cycle.
