Most common fault codes

Code	Severity	Plain English	DIY
Neon I3	Low	Your boiler is receiving power from the mains electricity, which is a normal status operation rather than a functional fault.	Yes
Neon SG	Low	Your boiler is currently trying to light the burner and you are seeing the normal indicator for the ignition spark.	Yes
Neon SG1	Low	This light is part of the boiler's normal starting process and shows it is currently trying to light the burner.	Yes
Neon1	High	Your boiler has detected that a vital safety switch is stuck in the 'on' position, preventing the system from starting its safety checks.	Engineer
Neon2	High	Your boiler is failing to start because the internal fan is not spinning correctly or the control board cannot confirm it is working.	Engineer
Neon3	High	Your boiler has lost power to its main control board, which means the system cannot operate or provide heating and 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.
