All 48 fault codes

Code Severity Plain English
0 Low Your boiler is working correctly and is simply waiting for a prompt from your thermostat or hot water tap to start up.
00 High Your boiler detects a flame when it should be turned off, which prevents it from starting up safely for its next cycle.
0-9 Low Your boiler is currently operating normally and is displaying the current temperature of the water inside the unit.
1 Low Your boiler is preparing to ignite by clearing out the combustion chamber, which is a normal part of its startup process.
01 High Your boiler has detected an electrical connection problem within its internal controls, causing it to shut down for safety.
2 High Your boiler is failing to light the burner though it is trying to start up.
02 High Your boiler is failing to light properly, which means it cannot heat your home or provide hot water.
3 Low Your boiler is operating normally and is currently running to provide heating for your radiators.
4 Low Your boiler is simply indicating that it is currently busy heating up your tap water.
04 High Your boiler has lost power while it was already trying to report a different fault, which has confused the system control board.
4* Low Your boiler is currently warming up its internal components to make sure hot water is available quickly when you turn on a tap.
5 Low Your boiler is temporarily pausing because it has reached its target temperature or is waiting for a signal to restart.
05 High Your boiler has stopped working because it has detected an electrical signal interference or a communication error between its internal components.
5* Low Your boiler is currently operating normally and is actively heating your radiators.
6 Low Your boiler is simply clearing out any remaining gases and cooling down after a period of activity, which is a normal part of its operation.
7 Low Your boiler is temporarily running the pump to circulate water and cool down internal components after the heating has been turned off.
8 Low Your boiler is simply running its pump for a few minutes to cool itself down after heating your hot water, which is a normal part of its operation.
9 Low Your boiler has temporarily paused because it has reached the required temperature and is waiting for the water in your radiators to cool down slightly before firing up again.
11 High Your boiler's internal computer parts have stopped talking to each other, meaning the unit cannot function.
18 High Your boiler has sensed that the water inside is getting too hot and has shut down as a safety precaution.
19 High Your boiler has detected that the water coming back from your radiators is too hot, which usually means the heat isn't being released into your rooms properly or water isn't flowing correctly.
24 High Your boiler has detected that the water coming back from your radiators is hotter than the water going out, which usually means the water isn't flowing correctly or the sensors are confused.
31 High Your boiler has detected a fault with the sensor that measures the water temperature leaving the unit, meaning it cannot safely monitor how hot the water is getting.
32 High Your boiler has stopped working because it cannot correctly measure the temperature of the water coming back from your radiators.
36 High Your boiler has detected that a key internal sensor responsible for tracking water temperature is either broken or disconnected, causing the system to stop working for safety.
37 High Your boiler has stopped working because it cannot correctly measure the temperature of the water returning from your radiators.
43 High Your boiler’s internal computer settings have become scrambled or are incorrect, preventing it from running safely.
77 High Your boiler has repeatedly failed to maintain a flame while running, causing it to shut down for safety.
A Low Your boiler is operating normally and is simply indicating that the water temperature being sent to your radiators has reached 60 degrees Celsius.
B Low Your boiler is temporarily pausing because it has reached its target heating temperature and is waiting for the water to cool slightly before firing again.
C Low Your boiler has reached its maximum programmed temperature for your central heating, which is often just a notification rather than a breakdown.
D Low Your boiler is simply finishing its cooling down cycle after being used and this is a normal part of its operation.
E Low Your boiler has detected very cold temperatures and is running the pump continuously to prevent the internal pipes from freezing.
E01 High Your boiler has switched itself off because it has become too hot to operate safely.
E02 High Your boiler has tried to light several times but has been unable to produce a flame, meaning you will have no heating or hot water until it is reset or repaired.
E03 High The main computer board inside your boiler has detected a software error or an internal malfunction and is unable to operate safely.
E04 High Your boiler has detected a problem with the internal sensor that measures water temperature, causing the system to shut down as a safety precaution.
E05 High Your boiler has stopped working because it cannot correctly read the temperature of the water returning to the unit.
E07 High Your boiler has detected an issue with the sensor that monitors the temperature of the exhaust gases, causing the system to shut down for safety.
E26 High Your boiler has sensed that the water returning from the radiators is hotter than the water leaving the boiler, which usually indicates that water isn't flowing through your system correctly.
E30 High Your boiler has detected that water is not circulating through the system quickly enough, causing it to overheat and shut down for safety.
E31 High Your boiler's hot water sensor has developed an electrical fault, meaning the system cannot tell how hot your water is and has stopped heating it for safety.
E32 High Your boiler is unable to read the temperature of the water coming out of your taps, which usually means your hot water will stop working or become unreliable.
F Medium Your boiler has noticed that the internal pump is running faster than expected while trying to heat your home, which often indicates a circulation problem or air in the system.
h Low Your boiler is currently running at its maximum power setting, which is a normal state used by engineers during testing or maintenance.
l Low Your boiler is currently locked in its lowest power setting, usually because a service engineer has manually set it to this mode for testing or it is performing a self-check.
Other codes High The main computer brain of your boiler has stopped working correctly, meaning the system cannot safely control the heating process.
P Low Your boiler is not broken; it has simply been put into setting mode, meaning it is waiting for a command or waiting to be returned to normal operation.
