Possible Causes

Clogged spray arms, Dirty filters and sump, Low water temperature, Weak circulation pump

How to Fix / Troubleshooting

Safety: Turn off power before removing internal components like spray arms if using tools.

  • Clean filters: Remove and thoroughly clean the coarse and fine filters in the bottom of the tub.
  • Clean spray arms: Remove upper and lower spray arms. Rinse under running water and use a toothpick to clear any blocked jets.
  • Check water temperature: Run hot water at the sink until hot before starting the dishwasher. Ensure your water heater is set to about 120°F (49°C).
  • Detergent and rinse aid: Use high-quality dishwasher detergent and ensure the rinse aid dispenser is filled.
  • Evaluate pump: If cleaning and proper loading do not improve results and the spray sound is weak, the circulation pump may be worn and require replacement.

Tip: Avoid overloading and blocking the spray arms with large items.
