How to Fix / Troubleshooting
Safety first: Turn off power and allow the motor to cool before touching.
- 1. Check for mechanical drag: Spin the motor shaft by hand with power OFF. If stiff, investigate bearings or impeller obstruction.
- 2. Improve cooling: Clear debris from vents and ensure adequate airflow around the motor.
- 3. Verify voltage and load: Have an electrician confirm correct supply voltage and that the pump is not overloaded by closed valves or a blocked filter.
- 4. Replace motor if needed: Persistent thermal cycling despite proper conditions indicates internal motor issues; replacement is recommended.
