Your boiler has detected that the water temperature is very low and has automatically activated the pump to keep the water moving and prevent it from freezing.
Your boiler has detected that the water temperature inside the system is getting too cold, so it has briefly activated its internal heating to prevent the pipes from freezing.
Your boiler has detected that it is getting too hot and has automatically shut itself down to prevent damage.
Your boiler is trying to start but cannot detect a flame, so it has safely shut itself down to prevent gas from building up.
Your boiler is overheating because the gases leaving the flue are hotter than they should be, causing the system to shut down for your safety.
Your boiler's internal computer has encountered a critical error, which is preventing it from safely starting or controlling your heating system.
Your boiler's main control computer is experiencing an internal error, which means it has safely shut down to prevent incorrect operation.
Your boiler's main computer board is failing to communicate correctly, which has caused the system to stop working entirely for safety reasons.
Your boiler is struggling to clear exhaust gases because the internal fan is not operating correctly, which prevents the unit from firing up safely.
Your boiler has stopped heating the water because it cannot move the water around the system effectively.
Your boiler is failing to ignite because it cannot detect a flame, meaning it has safely shut itself down to prevent a gas buildup.
Your boiler has detected that the temperature is near freezing and has activated its pump to keep the water moving and prevent it from icing up.
Your boiler has detected that the water inside the system is getting too cold and has activated its built-in frost protection mode to prevent pipes from freezing.
Your boiler has detected that water is not flowing properly around your heating system, so it has shut down to prevent damage.
Your boiler has detected that there is not enough water circulating inside the system to operate safely.
Your boiler is failing to detect the flow of water through the system, which is preventing it from safely starting up to provide heating or hot water.
Your boiler has lost the ability to detect the flow of water because an internal electrical sensor is sending a faulty signal, which prevents the heating and hot water from starting safely.
Your boiler is currently unable to read the temperature of the water returning to it, so it has shut down as a precaution to prevent overheating.
Your boiler is currently unable to read the water temperature accurately, which has caused it to stop working as a safety precaution.
Your boiler is having trouble reading the outside temperature because the connection to the external weather sensor is broken or disconnected.
Your boiler is struggling to read the temperature from an external sensor installed outside your home, which may cause your heating to run less efficiently.
Your boiler is struggling to keep the flame attached to the burner correctly, which causes it to shut down for safety reasons.
Your boiler has detected a flame inside when it should be turned off, which indicates a potential safety issue with the internal gas control system.
Your boiler is failing to confirm that the internal fan is venting exhaust gases safely, so it has stopped working to prevent a safety risk.
