Most common fault codes

Code	Severity	Plain English	DIY
Neon SG	High	Your boiler is currently trying to light the gas burner with a spark, but it is failing to sense a flame and stay on.	Engineer
Neon SG1	Low	Your boiler is currently trying to light the gas burner and is showing a normal status light while it generates an ignition spark.	Yes
Neon1	High	Your boiler has detected that the internal fan or air pressure system is sticking in the 'on' position, preventing the ignition sequence from starting safely.	Engineer
Neon2	High	Your boiler has detected an issue with the fan that safely removes exhaust gases, meaning it cannot start up for safety reasons.	Engineer
Neon3	High	Your boiler has lost power to its main control board, meaning it cannot operate and you will not have any heating or hot water.	Engineer

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.
