Possible Causes

Locked rotor due to seized bearings, Impeller jammed with debris, Shorted motor windings, Incorrect wiring or wrong voltage connection

How to Fix / Troubleshooting

Safety first: Isolate power at the breaker before touching the pump or motor. Do not continue trying to start a pump that trips on OC; this can damage the drive.

Step-by-step checks:

  • 1. Check for mechanical seizure: With power off, attempt to rotate the motor shaft by hand at the rear fan. If it will not turn or feels rough, the bearings or impeller are likely seized.
  • 2. Inspect wet end for blockage: Remove the pump lid and basket, then inspect the impeller area for stones, sticks, or other debris. Remove any obstruction carefully.
  • 3. Try a low-speed start: On variable speed models, set the pump to its lowest speed and attempt a start. If it still trips OC, stop and do not retry repeatedly.

OC that persists after clearing blockages indicates a motor or drive fault; professional repair or replacement is required.
