Hayward Seized Motor or Foreign Object Jam

Pump motor will not turn by hand; shaft is locked.

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

Severely worn bearings, Rusted shaft, Large debris wedged in impeller, Motor internal failure

Safety first: Turn off power and verify the pump cannot start unexpectedly.

Remove wet end: Separate the pump housing from the motor to isolate the motor shaft from the impeller.
Test motor shaft: Try turning the motor shaft by hand. If still locked, the motor is seized and must be replaced or rebuilt.
Inspect impeller: If the motor turns freely with the wet end removed, inspect the impeller and diffuser for large debris or damage causing the jam.
Replace damaged parts: Replace the impeller or motor assembly as needed.
