How to Fix / Troubleshooting
Safety: Immediately switch off power to the boiler at the isolator. Do not continue to operate the boiler.
- Do not remove covers while hot: Allow the boiler to cool before any inspection.
- Visual check (competent person): After cooling and with power isolated, remove the front cover and look for signs of burning, discoloured wiring, or melted plastic.
- Do not attempt makeshift repairs: Burnt components must be replaced, not taped or patched.
- Call a qualified technician: They will identify the failed component (pump, fan, PCB, wiring harness) and replace it, checking for underlying causes such as overcurrent or mechanical blockage.
