Sharp Circulation Pump Bearing Wear / Motor Noise

Dishwasher makes a high-pitched squealing or whining noise during operation.

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 pump bearings, Cavitation due to low water level, Debris partially contacting impeller, Faulty motor capacitor (if fitted)

Safety first: Disconnect power before accessing the base.

Verify water level: After filling, open the door briefly to confirm the water level is just below the filter. If low, check inlet issues.
Check for debris: Remove filters and inspect the sump for items rubbing against the impeller.
Assess pump noise: If squealing persists and is clearly from the pump, the Sharp circulation pump bearings are likely worn and the pump should be replaced.
