Pentair SuperFlo Thermal Overload Cycling

The pump motor runs briefly and then shuts off, repeating this cycle.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Overheating due to blocked ventilation, high ambient temperature, overloaded motor from mechanical binding, incorrect voltage.

Safety first: Turn off the power and allow the motor to cool before touching it.

1. Check for mechanical drag: Spin the motor shaft by hand with the power OFF. If stiff, investigate the bearings or impeller for obstruction.
2. Improve cooling: Clear debris from the vents and ensure adequate airflow around the motor.
3. Verify voltage and load: Have an electrician confirm the correct supply voltage and ensure 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.
