How to Fix / Troubleshooting
Safety first: Disconnect power and water. Beware of sharp objects like glass.
Step-by-step checks:
- Inspect interior: Ensure spray arms are not hitting tall items. Reposition dishes and re-test.
- Clean sump and filters: Remove filters and inspect the sump for bones, glass, or screws. Remove any foreign objects.
- Drain pump check: Access the drain pump from below, remove the pump cover, and check for debris around the impeller.
- Circulation pump bearings: If noise persists and is a constant growl, the circulation pump bearings may be worn. Replace the pump assembly.
After clearing obstructions or replacing the pump, run a short cycle to confirm quiet operation.
