Possible Causes
Aging pump motor bearings, Pump running dry or with restricted flow, Misaligned pump shaft
How to Fix / Troubleshooting
Safety first: Turn off power before touching the pump.
- Check for adequate water flow: Ensure water level is correct and filter is clean to prevent cavitation.
- Listen closely: If noise is clearly from the motor and not from water flow, the bearings are likely worn.
Motor bearing replacement or pump replacement is typically required and should be done by a spa technician.
