All 38 fault codes

Code Severity Plain English
200 O Low Your boiler is working normally and is currently heating up your radiators.
201 O Low Your boiler is simply letting you know that it is currently busy heating up the water for your taps or shower.
202 O Low Your boiler is taking a short, programmed break to prevent itself from turning on and off too frequently, which helps protect the internal components and improve efficiency.
203 0 Low Your boiler is working correctly but currently has no request from your thermostat or taps to provide heating or hot water.
204 O High Your boiler has stopped running because the water inside it has become hotter than the temperature you have requested.
208 0 Low Your boiler is currently in a manual testing mode used by engineers to check emissions, which means it is running at a fixed output rather than following your thermostat.
224 V High Your boiler has switched itself off because it has detected it is getting too hot, usually caused by the water pressure being too low.
227 V High Your boiler is failing to light the flame properly, meaning you will not have any heating or hot water until the issue is resolved.
228 V High Your boiler thinks it can see a flame even though it hasn't started the ignition process yet, which prevents it from running for safety reasons.
305 0 Low Your boiler has temporarily stopped heating water to prevent it from overheating and will automatically restart once it has cooled down.
306 V Emergency Your boiler is still detecting a flame even after it has tried to shut off the gas, which is a safety conflict that requires a professional inspection.
360 V High Your boiler's internal computer has lost communication with its identification chip or the chip installed is the wrong model for this unit.
815 W/B High Your boiler's temperature sensors are receiving conflicting or incorrect readings, causing the system to stop working correctly to protect itself.
1010 O High Your boiler's internal computer has lost its connection to its main controls, meaning it cannot receive the instructions it needs to provide heating or hot water.
1017 W High Your boiler has stopped working because the water pressure is too low and needs to be topped up.
1021 B High Your boiler is unable to provide hot water because it cannot accurately measure how hot the water is.
1022 B High Your boiler is unable to read the temperature of your hot water tank, which means your taps and showers may not get hot.
1037 W Low Your boiler has lost connection with its outdoor thermometer, meaning it might not adjust its heating efficiently based on the weather outside.
1065 B High Your boiler's internal water pressure sensor is not communicating properly with the control board, preventing the system from operating safely.
1068 W Low Your boiler is struggling to work out how hard it needs to fire because the sensor that monitors the weather outside has stopped sending a signal.
1073 W High Your boiler has detected an electrical fault with its main temperature sensor, which means it cannot safely monitor how hot the water is and has stopped working as a precaution.
1074 W High Your boiler has lost communication with its internal thermometer, meaning it cannot safely monitor the temperature of the water circulating through your radiators.
1075 W High Your boiler has detected an electrical fault with an internal temperature sensor, preventing the system from monitoring heat levels safely.
1076 W High Your boiler has lost communication with its internal temperature sensor, meaning it cannot monitor heat levels and has shut down as a safety precaution.
2920 V High Your boiler has stopped working because it cannot confirm that the flame is properly lit, causing the system to shut down for safety.
2924 V High Your boiler has detected an internal electrical communication error between the control board and the gas valve, preventing the burner from lighting safely.
2925 V High Your boiler has stopped working because it cannot properly communicate with the internal valve that controls the gas flow.
2927 B High Your boiler has lost its flame while running and has shut down for safety because it can no longer detect the fire needed to heat your water.
2946 V High Your boiler's internal computer chip is either missing or has failed, meaning the system doesn't know which specific model it's supposed to be.
2948 B High Your boiler is struggling to keep its flame lit during operation, which is causing it to stop and restart frequently.
2950 B High Your boiler is trying to light itself but cannot detect a flame, meaning your heating and hot water will likely stop working.
2963 B High Your boiler has detected an unusual temperature reading because a sensor or its wiring is not communicating correctly with the main control unit.
2964 B High Your boiler has detected that water is not moving through its internal heating unit fast enough, which can cause the system to overheat and shut down.
2965 B High Your boiler has shut down because the water inside is getting much hotter than it should be, which is often caused by a blockage or a pump failure preventing the heat from moving away.
2966 B High Your boiler is heating up too quickly and has shut down to prevent damage, usually because water isn't flowing through the system fast enough.
2967 B High Your boiler has detected that water is heating up too quickly or unevenly, causing it to shut down for safety to prevent overheating.
2970 B High Your boiler has detected that the water pressure in your radiators is falling much faster than expected, which could indicate a significant leak.
2971 B High Your boiler has detected that the water pressure in your heating system is too low to operate safely and effectively.
