The Dispenser Cap is an OEM part for Whirlpool dishwashers. It covers the detergent dispenser, ensuring that the detergent remains securely in place until it is dispensed during the wash cycle. This cap plays a vital role in the cleaning process by preventing detergent from spilling or dispersing too early, thereby optimizing the efficiency of the dishwasher.

Over time, the dispenser cap can become worn or damaged due to regular use, exposure to detergents, or accidental impacts. If the cap is compromised, it can lead to detergent leakage and ineffective cleaning.

Symptoms of a bad dispenser cap include:

  • Detergent not dispensing properly
  • Residual detergent left in the dispenser after the cycle
  • Leaks or drips around the dispenser area
  • Inefficient cleaning of dishes

This OEM part is also compatible with Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and Kenmore models.

Questions & Answers

For Whirlpool Dispenser Cap (Part Number: OEM18039621)

1 Answer

Hello Eric, The dispenser rinse aid cap would not cause the unit from dispensing soap. If the cap was melted while down inside the dispenser assembly then you will want to check the dispenser assembly for damage. A possible problem would be the wax motor on the dispenser failing and causing damage to the dispenser.
