Possible Causes
Blocked ventilation openings on PowerFlo motor, High ambient temperature and poor airflow, Overloaded motor due to high system pressure, Incorrect supply voltage or miswiring of PowerFlo motor
How to Fix / Troubleshooting
Safety first: Turn off power and allow the motor to cool before handling.
- Clear vents: Inspect the rear and sides of the PowerFlo motor for dust, leaves, or obstructions. Clean vents with a soft brush or compressed air.
- Improve airflow: Ensure the pump is not enclosed in a small, unventilated box. Provide adequate ventilation around the motor.
- Check system pressure: Read the filter pressure gauge. If pressure is high, backwash or clean the filter to reduce load on the pump.
- Verify voltage and wiring: Confirm that the PowerFlo motor is wired for the correct voltage and that the supply matches the nameplate. Incorrect voltage can cause overheating.
