Dishwasher is very noisy during wash, with grinding or rattling sounds.

Safety first: Disconnect power before reaching into the sump; wear gloves to avoid cuts.

• 1. Inspect interior: Check that spray arms are not hitting tall items or protruding cutlery. Reposition items as needed.
• 2. Clean sump: Remove filters and inspect the sump for glass shards, bones, or other hard objects. Remove carefully.
• 3. Check spray arms: Remove spray arms and shake them; if you hear rattling inside, debris may be trapped and the arm should be replaced.
• 4. Listen to pump: If grinding persists, the circulation pump may have internal damage and require replacement.
