Possible Causes

Broken glass or debris in wash pump, Loose items hitting spray arms, Worn pump bearings, Loose mounting hardware

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

Inspect tank: Remove racks and filters. Look for loose cutlery, glass, or other objects that may contact the spray arms.
Check spray arms: Spin arms by hand to ensure they rotate freely and do not strike racks or tank walls.
Inspect pump: Access the wash pump and check for foreign objects at the inlet. Remove any debris carefully.
Check bearings: If the noise is a loud hum or grinding from the pump motor, the bearings may be worn and the pump should be replaced.
