Possible Causes
Seized or partially seized motor bearings, Impeller jammed with debris, Incorrect voltage or wiring, Shorted motor windings
How to Fix / Troubleshooting
Safety first: Turn off power at the breaker before touching the pump or motor. Do not repeatedly reset an overcurrent fault without finding the cause.
- Check for mechanical blockage:
- Remove the pump lid and basket.
- Reach into the impeller opening and feel for stones, twigs, or other debris; remove carefully.
- Test shaft rotation:
- With power off, try to spin the motor shaft or cooling fan by hand.
- If it is stiff, gritty, or locked, the bearings are failing and the motor should be replaced.
- Verify wiring and voltage:
- Confirm the pump is wired according to the Jandy wiring diagram.
- Have a qualified electrician check for correct voltage and tight connections at the terminal block.
- Restart and monitor:
- After clearing debris and verifying free rotation, restore power and start the pump.
- If OC returns immediately, the motor windings or drive are likely damaged.
- Persistent OC fault: Replace the motor or complete pump assembly. This repair is best handled by a professional due to electrical safety and sealing requirements.
