Code Severity Plain English
A01 High Your boiler has failed to light the flame, which means you currently have no heating or hot water.
A02 High Your boiler detects a flame when it should be turned off, which prevents the system from starting up safely.
A05 High Your boiler has stopped working because the internal fan, which safely removes waste gases, is not spinning at the correct speed.
A06 High Your boiler is failing to stay lit after it tries to start up, meaning it cannot provide you with heating or hot water.
A07 Emergency Your boiler has shut down because the exhaust fumes have become dangerously hot, which could indicate a blockage or a heat exchanger problem.
A08 High Your boiler has sensed that parts of the internal system have become too hot, causing it to shut down automatically to prevent damage.
A09 High Your boiler has sensed it is getting much too hot and has shut itself down to prevent damage or dangerous overheating.
A10 High Your boiler's internal sensor has stopped correctly monitoring the water temperature as it leaves the unit, preventing it from heating up properly.
A11 High Your boiler has stopped working because it can no longer accurately measure the temperature of the water coming back from your radiators.
A13 High Your boiler has detected an issue with the sensor that monitors exhaust gases, causing the system to lock down for safety.
A14 Emergency Your boiler has shut down because it has detected a problem with how the exhaust fumes are being cleared from the property.
A42 High Your boiler has detected an unusual temperature difference between its sensors and has shut down to prevent any internal damage.
A54 High Your boiler's internal computer has encountered a critical electronic failure and can no longer control the heating or hot water safely.
A55 High Your boiler's internal computer has encountered a critical electronic failure and can no longer control the heating or hot water safely.
A56 High Your boiler is having trouble setting up its gas and air mixture correctly, which prevents it from firing up safely.
A61 High Your boiler's internal computer brain has detected a serious electronic failure and can no longer control the heating software correctly.
A62 High Your boiler has switched itself off because the main control board is unable to talk to the gas valve that fuels the flames.
A63 High Your boiler's internal computer has encountered a critical electronic failure and can no longer control the heating or hot water safely.
A64 High Your boiler has been manually reset too many times in a short period and has now locked itself out for safety.
A68 High Your boiler's internal memory card or control chip is failing to communicate correctly with the main computer board.
F07 Emergency Your boiler has shut down because the exhaust fumes have become dangerously hot, which could indicate a blockage or a heat exchanger problem.
F08 High Your boiler has sensed that parts of the internal system have become too hot, causing it to shut down automatically to prevent damage.
F09 High Your boiler has sensed it is getting much too hot and has shut itself down to prevent damage or dangerous overheating.
F10 High Your boiler's internal sensor has stopped correctly monitoring the water temperature as it leaves the unit, preventing it from heating up properly.
F11 High Your boiler has stopped working because it can no longer accurately measure the temperature of the water coming back from your radiators.
F12 Medium Your boiler's hot water sensor has stopped working, meaning the system cannot accurately monitor the temperature of the water coming out of your taps.
F13 High Your boiler has detected an issue with the sensor that monitors exhaust gases, causing the system to lock down for safety.
F14 Emergency Your boiler has shut down because the exhaust fumes have become dangerously hot, which could indicate a blockage or a heat exchanger problem.
F34 High Your boiler has stopped working because the electrical power supply coming into your home is currently too low for the system to operate safely.
F37 High Your boiler has stopped working because the water pressure inside the system is too low.
F39 Low Your boiler's outside temperature sensor has developed a fault or disconnected, meaning the system may struggle to automatically adjust its heating levels based on the weather.
F41 High Your boiler has sensed that the temperature is rising too quickly inside the unit, often caused by water not flowing through the pipes fast enough.
F42 High Your boiler has detected an unusual temperature difference between its sensors and has shut down to prevent any internal damage.
F43 High Your boiler has shut down to prevent the heat exchanger from overheating, often because the water isn't flowing through the system correctly.
F56 High Your boiler is having trouble setting up its gas and air mixture correctly, which prevents it from firing up safely.
F61 High Your boiler's internal computer brain has detected a serious electronic failure and can no longer control the heating software correctly.
F66 High Your boiler's main control board has detected an internal communication error, meaning it cannot process commands correctly.
F67 High Your boiler's computer or main control board has experienced a hardware error and cannot communicate with the rest of the system.
