Asko Pump Bearing or 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 circulation pump bearings, Worn drain pump bearings, Cavitation due to low water level, Foreign object partially contacting impeller

Safety: Disconnect power before accessing pumps.

Determine source: Listen carefully to identify whether the noise occurs during wash (circulation pump) or drain (drain pump).
Check water level: Ensure the dishwasher is filling to the correct level; low water can cause cavitation noise.
Inspect pump impellers: Remove and inspect the relevant pump for debris or damage.
Replace noisy pump: If the pump spins freely but still squeals, the bearings are likely worn. Replace the affected Asko pump assembly.
