6 High Your boiler is failing to light the gas or cannot detect the flame once it has started, meaning you will have no heating or hot water until it is fixed.
7 High Your boiler has switched itself off because it has started to overheat, usually due to a lack of water flow or a circulation problem.
8 High Your boiler is unable to safely clear exhaust fumes from the system, so it has shut down as a safety precaution.
9 High Your boiler has detected that there is either not enough water in the system or the pump is struggling to move it around correctly.
10 Medium Your boiler is likely struggling to provide hot water or maintain the correct temperature because its internal hot water thermometer has stopped working.
11 Medium Your boiler's heating system has a faulty internal temperature sensor that is preventing the radiators from warming up correctly.
23 High Your boiler has attempted to light but has failed to detect a flame, causing it to shut down for safety.
24 High Your boiler has likely overheated, causing it to shut down automatically as a safety precaution.
25 High Your boiler has stopped working because it cannot safely clear away exhaust fumes or the internal fan has failed to start.
26 High Your boiler has switched itself off because the water pressure is too low or the pump that moves water around your radiators isn't working correctly.
27 Medium Your boiler is struggling to correctly measure the temperature of your hot water, which usually means your taps will only provide lukewarm or cold water.
28 High Your boiler has detected that the part responsible for measuring the temperature of your heating water is no longer working correctly, causing the system to stop as a safety precaution.
30° neon flashing High Your boiler has detected an issue with the sensor that monitors the water temperature, causing the system to shut down as a safety precaution.
40° neon flashing Medium Your boiler has detected a problem with the sensor that measures hot water temperature, which means your taps may not get warm.
50° neon flashing High Your boiler has stopped working because the water pressure inside the system has dropped too low.
60° neon flashing High Your boiler has stopped working because it cannot safely vent waste gases or confirm that the fan is running correctly.
70° neon flashing High Your boiler has likely become too hot or water is not circulating correctly, causing it to shut down for safety.
80° neon flashing High Your boiler has tried to light but cannot detect a flame, which means it has locked itself out for safety.
Air pressure switch not proved (neons flashing) High Your boiler has detected an issue with how air and exhaust gases are moving through the system, preventing it from firing up for safety.
Burner extinguishes after 10 seconds (neon flashing) High Your boiler is lighting but cannot confirm the flame is present, causing it to shut down for safety.
Burner Neon (Flashing) High Your boiler has become too hot and has automatically shut down as a safety precaution.
Burner On Low Your boiler is working normally and the burner is currently lit to provide heating or hot water.
Directly after reset position (neon does not extinguish) High Your boiler is failing to clear its fault memory even after being reset, which usually means the internal control board or the reset switch itself has failed.
Fan runs at max speed (neon flashing) High Your boiler has detected a communication error or electrical fault that is causing the fan to run at full speed without igniting, meaning your heating and hot water will not work.
neon illuminated (fan/flue symbol) High Your boiler has detected an issue moving air or exhaust gases safely through the system, causing it to shut down for safety.
neon illuminated (flashing with cross symbol) High Your boiler has failed to ignite the gas burner and has gone into a safety lockout mode.
neon illuminated (tap/radiator symbols) High Your boiler has detected that there is not enough water pressure or the water isn't moving around the system properly to operate safely.
neon illuminated (thermometer symbol) High Your boiler has become too hot and has shut itself down as a safety precaution.
No neon illuminated High Your boiler has no power and the control panel lights are completely switched off.
Overheat thermostat operated (neon flashing) High Your boiler has switched itself off because it got too hot and needs time to cool down before it can be restarted.
Power Neon (Flashing) High Your boiler has detected an issue with how it clears exhaust gases, which has caused the system to shut down for safety.
Power On Low Your boiler is receiving electrical power and is ready for normal operation.
Preheat control neon flashing Medium Your boiler has detected an internal communication error or a disconnected jumper wire, which usually prevents the preheat function or the boiler from operating correctly.
Pressure below 0.5 High Your boiler has stopped working because the water pressure in the system has dropped too low to operate safely.
Pressure of 3 or greater Emergency Your boiler has too much water inside it, which is causing the safety valve to leak or trigger to protect the system from bursting.
Reset Neon (Flashing) High Your boiler has tried to fire up but could not light the flame, causing it to shut down for safety.
Spark at ignition electrodes (no neon flashing) High Your boiler is trying to start up but cannot successfully light the flame, leaving you without heating or hot water.
