LA Spas Worn Pump Bearings or Cavitation

Spa makes a high‑pitched whining or grinding noise from the pump area.

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 motor bearings, Pump running dry or with restricted flow, Misaligned pump and motor, Debris in pump wet end

Safety: Turn off power before inspecting the pump.

Check for adequate water: Ensure the spa is full and all valves are open to prevent cavitation.
Inspect for debris: Remove pump unions and check the impeller for foreign objects.
Replace pump or motor: If noise persists and bearings are rough, replace the pump or have the motor rebuilt.
