The site is intended to explain common meanings of fault codes and suggest safe first checks only. It should not be treated as a diagnosis of the exact failed part.

Fault-code meanings can vary by appliance model and context. Always check the manufacturer manual and any safety instructions supplied with the appliance.

Users should stop and seek qualified professional help if a repair would involve internal electrical components, gas systems, boiler casing access, sealed parts, water near electrics, persistent leaks, burning smells, or repeated lockouts.

If there is any immediate safety concern, such as suspected gas, smoke, burning smells, electrical tripping, flooding, or water reaching electrical parts, stop using the appliance and seek appropriate professional help.

Boiler pages are intended to help users understand what a displayed code usually relates to and what can be checked without opening the boiler casing.
