Dishwasher makes loud grinding or rattling noises during wash.

Safety first: Turn off and unplug the dishwasher before inspecting inside.

• Check loading: Ensure tall items are not obstructing spray arms. Reposition dishes and secure loose pans and cutlery.
• Inspect spray arms: Spin both spray arms by hand to check for free movement and listen for scraping.
• Check sump for debris: Remove filters and look into the sump for glass, bones, or other objects. Remove carefully.
• Access pump if needed: If noise persists, access the circulation pump from the base and inspect the impeller for foreign objects. Remove any debris.
