Possible Causes
Worn motor bearings, Debris jammed in impeller, Failed start/run capacitor, Low supply voltage to pump
How to Fix / Troubleshooting
Safety first: Turn off power and verify no voltage is present before touching the pump.
- Check for obstructions: Remove pump unions and inspect the impeller for stones, plastic, or other debris. Clear any blockage.
- Spin shaft manually: Try to rotate the motor shaft or rear cooling fan by hand. If it is stiff or seized, the motor likely needs replacement.
- Inspect capacitor: Locate the capacitor on the motor housing. If it is bulged or leaking, replace it with an identical µF and voltage rating component.
- Test operation: Reassemble, restore power, and briefly test. If the pump still only hums or trips the breaker, replace the complete pump assembly.
