Your boiler is struggling to accurately read the water temperature, causing it to shut down for safety because the readings are changing too quickly.

Your boiler has detected that its internal computer has become dangerously hot and has shut itself down to prevent fire or electrical damage.

Your boiler has detected an issue with the flame detection system, meaning it cannot confirm that the burner is safely lit and will refuse to operate as a precaution.

Your boiler is struggling to keep a steady flame, causing it to shut down for safety reasons.

Your boiler's electronic control panel is not communicating correctly with the main internal computer, which prevents the system from starting up safely.

Your boiler has lost the ability to accurately measure the temperature of the water used for your radiators, causing it to shut down for safety reasons.

Your boiler has detected an unusual temperature gap between the outgoing and incoming water, indicating the system is struggling to circulate heat correctly.

Your boiler is struggling to accurately measure the water pressure inside the system, which is preventing it from safely starting up your heating.

Your boiler's sensor is struggling to read your heating system's pressure, which prevents the unit from starting the heating or hot water safely.

Your boiler has detected an internal issue with a safety device designed to shut the system down if it gets too hot, and it will no longer operate until this is inspected.

Your boiler has detected an issue with the internal component that controls the gas supply, meaning it cannot safely ignite to provide heating or hot water.

Your boiler has detected that there is not enough water pressure inside the system for it to heat your home safely.

Your boiler is confused because its temperature sensors are giving conflicting readings or are not properly connected, causing it to stop heating your home to prevent potential damage.

Your boiler's temperature sensors are reporting conflicting information because they are detecting heat from the same spot, causing the system to stop heating for safety.

Your boiler is failing to light the flame needed to produce heat or hot water.

Your boiler is failing to light the flame, so it has safely stopped operating to prevent gas from building up inside.
