All 2 fault codes

Code	Severity	Plain English	DIY
Neon I3	Low	Your boiler is receiving power and has identified that the mains electricity is on, which is a normal status indicator rather than a fault.	Yes
Neon SG1	Low	Your boiler is currently trying to light the flame and this light will turn off as soon as the burner is successfully lit.	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.
