Most common fault codes

1
Your boiler has reached an unsafe temperature and has shut down to prevent damage or overheating.
May be DIY safe · £100-350
2
Your boiler's main internal temperature sensor has stopped working correctly, which means the system cannot safely monitor heat levels and has shut down as a precaution.
Gas Safe engineer required · £90-160
3
Your boiler is trying to start up but is failing to light the burner, meaning you will not have any heating or hot water.
May be DIY safe · £120-280

All 37 fault codes

Code Severity Plain English
0 Low Your boiler has reached the required temperature and is taking a short, normal break before it starts heating again.
1 High Your boiler has reached an unsafe temperature and has shut down to prevent damage or overheating.
2 High Your boiler's main internal temperature sensor has stopped working correctly, which means the system cannot safely monitor heat levels and has shut down as a precaution.
3 High Your boiler is trying to start up but is failing to light the burner, meaning you will not have any heating or hot water.
4 High Your boiler has detected a fault with one of its temperature sensors, which means it cannot accurately monitor the water temperature and has shut down as a safety precaution.
5 High Your boiler is struggling to light or cannot detect that a flame has started, so it has shut down for safety.
6 Low Your boiler has switched to prioritising hot water because it thinks a tap is currently running somewhere in your home.
7 Low Your boiler is currently pre-warming its internal water supply so that hot water reaches your taps faster when you turn them on.
8 High Your boiler has stopped working because the internal fan is spinning at the wrong speed, preventing the system from safely venting gases.
10 High Your boiler has detected a problem with its primary temperature sensor and has stopped working as a safety precaution.
11 High Your boiler has detected a problem with its primary temperature sensor and has stopped working as a safety precaution.
12 High Your boiler has detected a problem with its primary temperature sensor and has stopped working as a safety precaution.
13 High Your boiler has detected a problem with its primary temperature sensor and has stopped working as a safety precaution.
14 High Your boiler has detected a problem with its primary temperature sensor and has stopped working as a safety precaution.
20 High Your boiler has detected a problem with the temperature sensor that monitors the water returning to the unit, causing it to stop running for safety.
21 High Your boiler has detected a problem with the temperature sensor that monitors the water returning to the unit, causing it to stop running for safety.
22 High Your boiler has detected a problem with the temperature sensor that monitors the water returning to the unit, causing it to stop running for safety.
23 High Your boiler has detected a problem with the temperature sensor that monitors the water returning to the unit, causing it to stop running for safety.
24 High Your boiler has sensed that the water returning from your radiators is hotter than the water leaving the boiler, which usually means there is a circulation problem or a sensor fault.
29 High Your boiler has detected an issue with the fan, which means it cannot safely move air and gas through the system to start the heating process.
30 High Your boiler has sensed that the water returning to it is significantly hotter than the water going out, which usually means there is a blockage or a sensor error causing the system to stop for safety.
7777 Low Your boiler has detected very cold temperatures and has automatically turned on to prevent the internal water from freezing and damaging the pipes.
E01 High Your boiler is trying to light but cannot spark or maintain a flame, meaning you have no heating or hot water.
E02 High Your boiler has shut down because the water inside it has become too hot, causing it to overheat for safety.
E03 High Your boiler has shut down because its internal temperature sensors have detected that the exhaust gases are getting too hot, which could damage the system.
E04 High Your boiler has detected that the water pressure is too low for it to run safely, or there is a blockage preventing water from circulating.
E05 High Your boiler has detected that the fan, which safely removes waste gases, is spinning at the wrong speed or has stopped working entirely.
E10 High Your boiler has stopped working because it cannot correctly monitor the temperature of the water leaving the unit.
E11 High Your boiler has detected a problem with one of its internal temperature sensors, which prevents it from monitoring the water returning to the unit correctly.
E12 Medium Your boiler's hot water sensor has failed or detected an error, meaning the system cannot accurately measure the temperature of your tap water.
E13 High Your boiler has detected a problem with the sensor that monitors exhaust fumes, causing the unit to shut down for safety.
E27 Low Your boiler is having trouble reading the outside temperature and is unable to adjust your heating efficiently.
E29 High Your boiler's electronic brains have encountered an internal software or communication error and can no longer control the heating safely.
E31 High Your boiler has detected that the internal temperature sensors have been mixed up or are reading in the wrong order, preventing it from heating your water safely.
E36 High Your boiler thinks it sees a flame even though it hasn't started the ignition process yet, which is a safety error that prevents the unit from firing up.
h Low Your boiler is currently running at its maximum power for testing or maintenance purposes and is not indicating a fault.
L Low Your boiler is currently running in a manual test mode used by engineers and is not experiencing an actual fault.
