All 10 fault codes

Code Severity Plain English
A Low Your boiler is receiving power and is operating normally; this is a status indicator rather than a fault.
A short pulse every 4 seconds Low Your boiler is currently on standby and is running its built-in protection mode to prevent the internal pipes from freezing during cold weather.
All lamps activated (Service operation) Medium Your boiler has been switched into a special technician mode used for tuning the gas settings and will not operate normally until this is deactivated.
E High Your boiler has stopped running because it has detected an operational fault and has locked itself out for safety.
Flashing lamp, alone or simultaneously with another lamp High Your boiler has detected that the water inside the system is getting too hot and has shut down as a safety precaution.
Flashing lamp, alternate with another lamp (LED 1 and LED 2) High Your boiler has detected an issue with the sensor that monitors the temperature for your central heating, meaning it cannot safely regulate how hot your radiators get.
Flashing lamp, alternate with another lamp (LED 1 and LED 3 with LED 2 ON) High Your boiler is failing to light the gas flame despite trying to start, which has caused the system to shut down for safety.
Flashing lamp, alternate with another lamp (LED 1 and LED 3) Medium Your boiler is having trouble measuring the temperature of your hot water, which usually means it cannot heat water for your taps correctly.
Flashing lamp, alternate with another lamp (LED 1, LED 2 and LED 3) High Your boiler has detected that there is not enough water pressure or the water is not moving through the system properly.
Very fast pulses (4 per second) High Your boiler has detected a general internal fault that could be caused by anything from low water pressure to the unit overheating.
