Disclaimer

The site explains documented meanings within their stated scope and labels unconfirmed meanings explicitly. An operating message is not necessarily a fault. Neither a code definition nor a severity label establishes the exact failed part or whether an appliance is safe to use.

Code meanings can vary by complete display, appliance model, series and region. Check the exact model manual and the manufacturer's safety instructions before taking action. A generic maintenance suggestion must not override an instruction to contact service.

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.

ApplianceFaults does not replace a manufacturer, qualified technician, qualified heating or gas professional, Gas Safe registered engineer in the UK, electrician, or emergency service.

Fire, smoke, suspected gas leaks and carbon-monoxide alarms require emergency guidance, not a routine repair booking. See the UK emergency guidance on this page; outside the UK use local emergency services and your gas supplier.

Do not approach wet or damaged electrical parts to unplug an appliance. Only isolate it if safe and in line with its instructions. Do not move or dismantle an unsafe appliance to find its model number or take a photograph.

Boiler pages explain the documented display and its limits, with user actions kept outside the casing. In the UK, employ a Gas Safe registered engineer competent for the specific gas work and check the categories on their ID card.

Do not remove boiler covers, adjust gas components, work on combustion parts, or bypass boiler safety systems based on this website.
