Code Severity Plain English
BURNER STAYS ON Emergency Your boiler's internal burner is failing to switch off even when you are not using hot water or heating, which suggests a mechanical component is stuck or blocked.
EXPLOSIVE IGNITION Emergency Your boiler is struggling to light smoothly and is experiencing small mini-explosions or loud bangs when it tries to start.
FAULT FINDING CHART High Your boiler has detected a system error that it cannot automatically resolve, requiring a technician to consult the internal diagnostic guide to pinpoint the cause.
GAS CONTROL TAP STIFF (USER’S) High The dial you use to turn your boiler's gas supply on or off is difficult to move, preventing you from operating the boiler correctly.
GAS CONTROL TAP STIFF (USERS) High The dial you use to turn your boiler's gas supply on or off is physically jammed, making it difficult or impossible to operate safely.
HEATING BODY NOISE High Your boiler is making loud banging or kettling noises because of a buildup of limescale or poor water circulation, which is causing parts to overheat.
HEATING BODY VOISE High Your boiler is making loud banging or whistling noises because internal components are likely clogged with limescale or struggling with water flow, which can cause the system to overheat.
INSUFFICIENT WATER FLOW High Your boiler is struggling to detect the flow of water necessary to ignite and provide you with heating or hot water.
MAIN BURNER DOES NOT LIGHT High Your boiler is failing to ignite because it isn't receiving enough gas or water flow to start the heating process.
PILOT FLAME DOES NOT LIGHT High Your boiler is failing to ignite because it cannot start the small flame needed to safely light the main burner.
PILOT WILL NOT STAY ALIGHT Emergency Your boiler's small starter flame keeps blowing out or failing to stay lit, which prevents the main boiler from igniting and providing heating or hot water.
PILOT WILL NOT STAY ALIGm Emergency Your boiler's pilot light is failing to remain lit, which prevents the main heating system from starting up safely.
POOR PILOT FLAME Emergency Your boiler is struggling to keep its small starter flame lit, so it has safely shut down to prevent gas from building up.
SOOT FORMED Emergency Your boiler is struggling to breathe, causing a build-up of waste material that indicates it is not burning gas cleanly, which can be dangerous.
UNSTABLE FLAMES Emergency Your boiler is struggling to keep its internal fire burning steadily, which often indicates an issue with the air supply or a blockage in the exhaust system.
WATER TEMPERATURE High Your boiler is struggling to heat your hot water properly, usually because the water is flowing through it too quickly for it to warm up or because the gas supply is restricted.
YELLOW FLAMES Emergency Your boiler is burning gas inefficiently, which is dangerous and can lead to the production of poisonous carbon monoxide gas.
YELLOW FLAMES / SOOT FORMED Emergency Your boiler is not burning fuel cleanly, which creates a significant risk of toxic fumes escaping into your home.
YELLOW FLAMES SOOT FORMED Emergency Your boiler is not burning fuel correctly, which is causing soot buildup and indicates a significant safety risk from potentially harmful gases.
