Davey pool pump controller shows PF and the pump will not start.

Safety first: Do not repeatedly reset breakers that trip immediately; this can be dangerous.

Step-by-step checks:

• 1. Confirm mains power: Check that other appliances on the same circuit have power.
• 2. Inspect plug and isolator: Ensure the pump plug (if fitted) is fully inserted and the isolator switch near the pump is ON.
• 3. Reset controller: After stable power is restored, press the START/RESET button on the Davey controller to clear PF.
• 4. Monitor for repeat events: If PF appears frequently, have an electrician check the supply and protective devices.
