Machine is very noisy during wash, with grinding or rattling sounds from inside the cabinet.

Safety: Disconnect power and wait for moving parts to stop before inspection.

• Check racks and load: Ensure racks are correctly positioned and utensils are not protruding into the path of the spray arms.
• Inspect spray arms: Spin the arms by hand to check for contact with racks or tank walls. Adjust or replace bent arms.
• Check for foreign objects: Remove tank filters and inspect the sump and pump inlet for glass, screws, or other debris. Remove carefully.
• Assess pump bearings: If noise persists and seems to come from the pump motor, the bearings may be worn. Replace the wash pump assembly.
