Most common fault codes

Code	Severity	Plain English	DIY
Green light	Low	Your boiler is working correctly and is simply indicating that the internal burner is lit and ready to provide heating or hot water.	Yes
Red light	High	Your boiler has shut down for safety because it cannot maintain a steady pilot light or has detected a problem with how waste gases are being removed.	Yes

Parts for discontinued models can be hard to find and expensive. A new A-rated boiler could save you money on both repairs and energy bills.
