How to Fix / Troubleshooting

Safety first: Disconnect mains power and allow hot water to cool before working underneath.

  • Check spray arms: Ensure they are not blocked by dishes and can spin freely by hand.
  • Listen for pump: During wash phase, listen for the sound of the circulation pump. A loud hum or silence indicates a problem.
  • Inspect sump: Remove filters and check for debris blocking the pump inlet.
  • Access pump: Lay the dishwasher on its back, remove the bottom panel, and inspect the circulation pump and wiring. Replace the pump if it is seized or electrically faulty.
