How to Fix / Troubleshooting
Safety first: Only qualified persons should open electrical enclosures. Always isolate power before inspecting wiring.
Step-by-step checks (user level):
- 1. Check breaker and RCD: Reset if tripped. If it trips again immediately, stop and call an electrician.
- 2. Verify isolator: Ensure the pump's local isolator switch is ON.
- 3. Inspect plug/socket: If the pump is plug-in type, test the outlet with another appliance.
Technician-level checks:
- 4. Check terminal connections: Tighten any loose wires in the pump terminal box.
- 5. Test internal power supply: Measure low-voltage outputs from the controller's power supply section.
If there is correct mains at the pump but no display, the controller PCB may need replacement.
