How to Fix / Troubleshooting
Safety first: Only work on electrical circuits if you are competent. Otherwise, call an electrician or engineer.
- Check fused spur: Ensure the boiler's switch is on and the fuse (typically 3A) is intact; replace with the correct rating if blown.
- Check consumer unit: Verify that the circuit breaker or RCD feeding the boiler has not tripped; reset if safe to do so.
- Confirm power at spur: Plug in another appliance to confirm the spur has power.
- Engineer checks:
- Inspect the boiler's internal mains terminal block for loose or burnt connections.
- Test incoming voltage and the PCB's low-voltage outputs.
- Replace the main PCB if the internal power supply has failed.
