How to Fix / Troubleshooting
Safety: Turn off power before touching the pump or motor.
- Check for air: Bleed the pump unions to remove air and ensure the spa is filled to proper level.
- Inspect mounting: Verify that the pump is securely bolted to the equipment base and that rubber isolation mounts are intact.
- Listen to motor: If noise persists with good water flow and no air, the motor bearings are likely failing and the pump should be replaced or rebuilt.
