This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Foreign object in circulation pump, Worn pump bearings, Loose spray arm hitting dishes, Items protruding through basket

Safety first: Unplug the dishwasher before inspecting the sump or base.

Check loading: Ensure utensils and tall items are not contacting the spray arms. Reposition items and test.
Inspect spray arms: Spin the arms by hand to confirm they rotate freely without hitting racks.
Check sump for debris: Remove filters and look for glass, bones, or hard objects. Remove carefully.
Access pump if noise persists: Remove the base panel and inspect the circulation pump for play in the shaft or signs of bearing wear. Replace the pump if noisy.
