Panasonic Worn Pump Bearings or Motor

Dishwasher makes high-pitched squealing or whining noise

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

Worn circulation pump bearings, Cavitation due to low water level, Foreign object partially contacting impeller

Safety first: Disconnect power before accessing the base.

Verify water level: Ensure the dishwasher is filling to the correct level; low water can cause cavitation noise.
Check for debris: Inspect the sump and pump inlet for objects lightly touching the impeller.
Assess pump condition: If squealing persists with correct water level and no debris, the circulation pump bearings are likely worn and the pump assembly should be replaced.
