Beko Pump Bearing Wear / Cavitation

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 circulation pump bearings, Air in water system causing cavitation, Restricted water inlet, Debris partially contacting impeller

Safety: Unplug the dishwasher before accessing the base.

Check water supply: Ensure adequate water pressure and a fully open tap to reduce cavitation.
Bleed air: Start a cycle and open/close the door briefly after filling to help purge air.
Inspect pump: If noise persists, access the circulation pump and check for debris or signs of bearing wear (play in shaft, water ingress).
Replace pump: If bearings are noisy or rough, replace the circulation pump assembly.
