Most common fault codes

Code	Severity	Plain English	DIY
Loss of system water pressure	High	Your heating system is losing water through a leak, causing the pressure to drop too low for the boiler to operate safely.	Yes
Neon I3	Low	Your boiler has electrical power and is ready to operate as normal; this light is a status indicator rather than a fault.	Yes
Neon SG1	Low	This light simply shows your boiler is currently trying to light the flame and is a normal part of its operation.	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.
