Dishwasher makes loud grinding or rattling noises during wash or drain.

Safety: Disconnect power before reaching into the sump or pump area.

• Inspect interior: Remove racks and check for loose cutlery or small items that may contact spray arms.
• Check spray arms: Spin spray arms by hand to ensure they rotate freely and do not strike dishes.
• Clean sump and drain pump: Remove filters and open the drain pump cover. Remove any foreign objects from the impeller area.
• Check circulation pump: If noise persists, access the circulation pump from the base and inspect for debris or worn bearings. Replace the pump if bearings are noisy or loose.
