How to Fix / Troubleshooting
Safety first: If you smell burning plastic or see smoke, immediately turn off power and gas to the boiler. Do not continue to use it.
- Ventilate the area: Open windows and doors to disperse any fumes.
- New boiler note: A slight smell on first use can be normal as oils burn off, but it should dissipate quickly and not be accompanied by smoke or repeated strong odour.
- Engineer checks:
- Inspect internal wiring and components for signs of overheating or melting.
- Check pump and fan motors for overheating and replace if necessary.
- Ensure no plastic or packaging remains near the burner or flue.
