Whirlpool Dishwasher Not Cleaning — Causes & Repair Parts

Whirlpool dishwasher showing dishwasher not cleaning? Here are the 4 most common causes, how to diagnose each, and 8 OEM-compatible repair parts available with fast US shipping.

Common Causes of Not Cleaning in Whirlpool Dishwashers

  1. Spray arms clogged or broken: Mineral deposits or food particles block the spray arm holes, reducing water pressure to dishes.
  2. Wash pump motor failure: The circulation pump forces water through the spray arms. A weak or failed pump means poor cleaning.
  3. Low water temperature: Water below 120°F cannot dissolve detergent effectively. Check water heater settings.
  4. Detergent dispenser not opening: The dispenser spring or bi-metal latch breaks, leaving detergent trapped inside during the wash cycle.

How to Diagnose Your Whirlpool Dishwasher

  1. Unplug the dishwasher or trip the dedicated circuit breaker before any inspection.
  2. Remove and clean the filter basket at the bottom of the tub — rinse under running water.
  3. Inspect the spray arm holes for clogging — use a toothpick to clear blocked jets.
  4. Check the door gasket for cracks, missing sections, or debris preventing a tight seal.
  5. Run a short cycle and observe water fill level — should reach the bottom of the door.
  6. Test the door latch for proper engagement by firmly pressing the door closed and listening for a click.
  7. Check for error codes on the display and consult the manufacturer service manual.
