How to Fix / Troubleshooting
Safety: Turn off power at the GFCI breaker before inspecting the pump.
- Confirm noise source: Remove the equipment panel and run the pump briefly to verify the noise is from the pump motor, not loose plumbing.
- Check for leaks: Inspect the pump seal area for water leaks that may have entered the motor.
- Secure mounting: Ensure the pump is firmly mounted to the base to reduce vibration.
Pump motors with failed bearings should be replaced or rebuilt. Continued use can lead to seizure and further damage.
