High-pitched squealing or whining noise during drain

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 drain pump bearings, Debris rubbing on impeller, Cavitation due to partial blockage

Safety first: Disconnect power before working on the drain pump.

Clean filters and sump: Remove debris that could reach the drain pump.
Inspect drain pump: Access the pump from the base, remove it, and check for foreign objects around the impeller.
Check for play: Wiggle the impeller shaft; excessive play indicates worn bearings.
