How to Fix / Troubleshooting

Safety first: Repeated tripping indicates a serious electrical fault. Do not keep resetting breakers without investigation. Risk of fire or electric shock.

Step-by-step checks (visual only):

  • 1. Inspect for visible damage: With power off, remove the front panel and look for burnt wires, scorch marks, or melted insulation.
  • 2. Isolate components (for professionals): A technician can disconnect pump, fan, and other loads one by one to identify the faulty component.

When to stop: Electrical fault-finding should be done by a qualified electrician or heating engineer. Do not attempt to bypass fuses or use overrated fuses.
