Code Severity Plain English
<00 High Your boiler is struggling to operate its internal fan correctly, which prevents it from firing up safely.
0 Low Your boiler is perfectly healthy and is simply waiting for a signal from your thermostat or timer to start heating up.
0! High Your boiler has detected an electrical fault in its internal wiring, which has caused it to shut down for safety reasons.
0) Emergency Your boiler has detected that a flame is still present even though it has commanded the gas to turn off, which poses a significant safety risk.
0@ High Your boiler has failed to light because it cannot detect a flame, meaning you currently have no heating or hot water.
0* High Your boiler's internal computer settings have become scrambled, preventing it from understanding how to safely start or run.
0% Medium Your boiler is struggling because electrical interference from nearby devices or poor wiring is disrupting its computer systems.
0$ High Your boiler has experienced a power interruption following an earlier, currently hidden problem that caused it to shut down for safety.
1 Low Your boiler is currently performing a standard safety air-clearing routine and is not reporting an active system fault.
1! High Your boiler has lost the ability to send signals between its internal controls, likely due to a loose wire or moisture inside the display unit.
1( Medium Your boiler has detected that the water returning to it is much hotter than expected, so it has shut down to prevent overheating.
1* High Your boiler has shut down because it cannot circulate enough water to keep the internal heat at a safe level.
2 High Your boiler is failing to light the flame, which means it cannot produce heat or hot water.
2( High Your boiler has detected an issue with the internal fan that pushes air through the system, causing it to stop its normal operation to prevent a safety risk.
2* High Your boiler has detected that the internal fan is not spinning, so it has safely shut itself down to prevent any risk of incomplete combustion.
2$ High Your boiler is confused because it detects that the water is circulating in the wrong direction or the pipes are connected the wrong way round.
3 Low Your boiler is working normally and is currently running in heating mode.
3! High Your boiler has stopped working because it cannot correctly read the temperature of the water flowing through it, so it has shut down as a precaution.
3@ High Your boiler has detected a faulty signal from one of its internal heat sensors, causing it to stop operating as a safety precaution.
3& High Your boiler has lost its connection to a temperature probe, meaning it cannot accurately monitor the water circulating back into the system, causing the unit to shut down to prevent potential overheating.
3^ High Your boiler has stopped working because it has lost contact with the internal component that measures how hot the water is.
3$ Low Your boiler has lost the signal from the weather sensor outside, which means it cannot automatically adjust your heating based on the outdoor temperature.
4 High Your boiler is struggling to switch between heating your radiators and heating your hot water.
4) High Your boiler has detected an incorrect internal setting that prevents it from starting up correctly.
5 High Your boiler has detected an internal error during its self-test and has safely shut itself down to prevent damage.
6 Low Your boiler has temporarily switched itself off because the water inside is already hot enough to meet your current settings.
7 Low Your boiler is currently running its internal pump to safely move leftover heat away from the burner after your heating or hot water has switched off.
7& High Your boiler is failing to stay lit because it cannot reliably detect a flame or is struggling to breathe properly through its flue system.
8 Medium Your boiler is struggling to switch between heating your radiators and heating your hot water tank, causing it to pause operations to prevent overheating.
9 Low Your boiler has temporarily stopped heating the water because it has already reached its target temperature and is simply performing a normal automatic safety pause.
12 High Your boiler has detected a safety issue with its internal systems and has shut itself down to prevent any damage or danger.
37 High Your boiler has detected an incorrect reading from a internal temperature sensor, causing it to stop operating as a safety precaution.
b Low Your boiler has temporarily paused heating because a safety device or external control, such as a frost thermostat or room controller, has sent a signal to stop the system.
B@( High Your boiler is failing to start because it cannot detect that the air fan is spinning at the required speed to operate safely.
B@* High Your boiler is struggling to get the air flowing properly to ensure safe combustion, and after several repeated failed attempts, it has turned itself off for safety.
B@% High Your boiler is overheating because it cannot move the hot water away fast enough, so it has temporarily turned itself off to cool down.
b@^ High Your boiler has detected that an external safety device, such as a high-limit thermostat or a flue gas monitor, has temporarily broken the electrical circuit, causing it to pause operations for safety.
B#) Medium Your boiler has temporarily stopped because it cannot move heat away from its internal components fast enough, which often points to restricted water flow in your radiator system.
B$# High Your boiler's internal settings have been altered or corrupted, causing it to stop functioning until these values are corrected.
bXX Low Your boiler has temporarily stopped because it is waiting for the system to reach the correct temperature or a specific safety condition to be met before restarting.
E00 High Your boiler's internal computer has encountered a serious internal error and has shut down to prevent further damage.
E01 High Your boiler has failed to start its flame successfully after several attempts, so it has turned itself off for safety.
E02 High Your boiler is trying to start but cannot detect a flame, so it has safely shut itself down to prevent gas from building up.
E03 Emergency Your boiler is detecting a flame inside the unit even before it has tried to start up, which prevents it from operating safely.
E04 High Your boiler has successfully lit the flame, but it is repeatedly going out while running, causing the system to lock itself for your safety.
E05 High Your boiler is struggling to push air through for combustion, so it has safely shut itself down to prevent ignition problems.
E06 High Your boiler has stopped heating because it has lost the ability to read the temperature of the water flowing through it due to a faulty electrical connection or sensor.
E07 High Your boiler has stopped working because it is unable to accurately measure the temperature of the water returning to it, so it has shut down to protect itself.
E08 High Your boiler is confused because it senses the water temperatures are flowing in the wrong direction or are unevenly matched.
E09 Emergency Your boiler has detected an issue with the internal component that regulates and monitors its gas supply, meaning it will remain safely shut down until a professional can inspect it.
E10 High Your boiler has detected that the water pressure inside the system is currently too low to operate safely, causing it to shut down to prevent damage.
E11 High Your boiler has detected that the water inside the system is getting too hot or is not circulating properly, so it has safely shut down to prevent damage.
