How to Fix / Troubleshooting

Safety: Turn off power before removing spray arms if accessing from below.

  • Clean filters and sump: Remove and thoroughly clean filters and any debris from the sump.
  • Clean spray arms: Remove and flush spray arms, clearing all jets with a toothpick.
  • Review loading pattern: Avoid nesting dishes and blocking spray arms. Place large items at sides and back.
  • Use proper detergent and rinse aid: Use a high-quality dishwasher detergent and ensure rinse aid dispenser is filled.

If performance remains poor after cleaning and proper loading, the circulation pump may be weak and require replacement.
