Jacuzzi Seized Pump Motor or Failed Start Capacitor

Pump hums but does not start; may trip the breaker after a few seconds.

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

Locked rotor due to corrosion, Failed start capacitor, Debris jammed in impeller, Low supply voltage

Safety: Turn off power and do not repeatedly reset a tripping breaker.

Check for obstructions: Remove pump unions and inspect the impeller for foreign objects.
Spin shaft (advanced): If accessible, try to rotate the motor shaft by hand with power off. If it is stuck, the motor is seized.
Inspect capacitor: Locate the pump's start capacitor (metal or plastic can on motor). Bulging or leaking indicates failure and it should be replaced with the same rating.

If the motor remains seized or trips the breaker, replace the pump assembly.
