Code Severity Plain English
02E High Your boiler is struggling to move water around the system, which is causing it to shut down to prevent overheating.
03E High The boiler's internal sensor that monitors water temperature or flow has failed, meaning the system cannot safely regulate heat.
04E Medium Your boiler's hot water sensor has failed, which means the system cannot accurately heat water for your taps and showers.
05E High Your boiler has detected a problem with the fan that clears exhaust gases, preventing it from starting safely for heating or hot water.
06E High Your boiler is getting too hot inside, which has triggered a safety shutdown to prevent damage to the system.
08E High Your boiler has detected that there is not enough water in the system to operate safely.
09E High Your boiler has shut down because it has detected that the water inside is getting too hot, usually due to a circulation blockage or a pump failure.
10E Emergency Your boiler has too much water in the system, which causes it to shut down for safety.
13E High Your boiler's computer system has encountered a processing glitch and has stopped working to protect itself.
21E High Your boiler has detected that the water returning from your radiators is too hot, which has caused it to shut down for safety.

31E High Your boiler is having trouble 'talking' to your smart thermostat or external heater controls, meaning it may not receive instructions to turn on or off.
41E High Your boiler has detected that the water isn't moving through the system correctly, causing a large temperature gap between the pipes.
42E High Your boiler has shut down because there is a confusing difference between the temperatures recorded at its internal sensors, often caused by poor water flow or a sensors reading incorrectly.
44E High Your boiler has detected an unusual temperature difference between the pipes, causing it to shut down to prevent overheating.
46E High Your boiler has detected a problem with the sensor that monitors internal water pressure, meaning it cannot confirm if there is enough water to operate safely.
