Possible Causes
Intermittent low-flow condition triggering protection, Overheating and thermal cut-out cycling, Faulty flow or pressure sensor, Loose power supply causing brief outages
How to Fix / Troubleshooting
Safety first: Repeated cycling can damage the motor and electronics. Turn off the pump while diagnosing.
Step-by-step checks:
- 1. Check for flow issues: Clean baskets and filter, ensure valves are open, and verify the pump is fully primed.
- 2. Inspect for overheating: Feel the motor casing after a short run; if extremely hot, address ventilation and load issues.
- 3. Check power stability: Ensure the plug or isolator is not loose and that there are no obvious supply interruptions.
If cycling continues with good flow and stable power, a sensor or controller fault is likely and should be assessed by a technician.
