AstralPool Bearing or Cavitation Noise

Pump is running but makes a high-pitched whine or screeching noise.

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

Early-stage bearing wear, Pump running partially dry causing cavitation, Suction restriction or air ingress

Safety first: Turn off power before opening the pump.

Eliminate cavitation: Ensure the pump is fully primed, suction valves are open, and water level is adequate. Clean baskets and check for suction line blockages.
Listen after corrections: If the whine persists with good flow and no air bubbles, the motor bearings are likely starting to fail.
Schedule repair: Plan for motor or bearing replacement before complete failure to avoid sudden downtime.
