Dishwasher is very noisy during operation; grinding, rattling, or loud humming sounds.

Safety First: Turn off power before inspecting internal components.

• Check loading: Ensure tall items are not contacting the spray arms. Spin arms by hand to confirm free movement.
• Inspect for debris: Remove filters and check the sump for bones, glass, or hard objects contacting the impeller. Remove carefully.
• Level the unit: Adjust leveling legs so the dishwasher is stable and not touching the cabinet sides.
• Replace noisy pump: If noise persists and seems to come from the motor area, the circulation pump bearings may be worn. Replace the circulation pump assembly.
