Electrolux Pump or Motor Bearing Wear

Dishwasher makes a high-pitched whining or squealing 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 circulation pump bearings, Cavitation due to low water level, Foreign object partially contacting impeller, Misaligned pump mounting

Safety first: Turn off power before accessing the base.

Verify water level: Ensure the dishwasher is filling to the correct level; low water can cause pump cavitation noise.
Inspect for debris: Check the sump and pump inlet for objects lightly contacting the impeller.
Check pump mounting: Confirm the circulation pump is securely mounted and not vibrating against the chassis.
Replace pump: If bearings are worn and noise persists, replace the Electrolux circulation pump.
