Indesit Circulation Pump Bearing Wear / Cavitation

Dishwasher makes a high‑pitched whining noise during wash, louder than usual.

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 circulation system due to low water level, Partially blocked sump filter causing cavitation

Safety: Disconnect power before accessing panels.

Basic checks:

Ensure filters are clean and correctly seated.
Confirm the machine is filling to the correct level (water just below the bottom of the door seal).

Pump assessment:

If the noise persists with correct water level and clean filters, access the circulation pump.
Spin the impeller by hand; a rough or loose feel indicates bearing wear.
Replace the circulation pump assembly if bearings are noisy.
