Glow-worm Energy7 12s-A Fault codes & diagnostics

Your boiler has temporarily stopped working because it has lost the signal from one of its internal temperature sensors.

Your boiler has temporarily stopped working because it cannot properly read the temperature of the water returning to it.

Your boiler has stopped working because it cannot properly read the water temperature due to a faulty sensor or wiring issue.

Your boiler has detected a faulty reading from an internal water temperature sensor, which temporarily stops the heating system from operating safely.

Your boiler has detected that it is running too hot and has automatically turned itself off as a safety precaution to prevent damage.

Your boiler has stopped working because it has detected that the water pressure inside the system is too low to run safely.

Your boiler has detected that water is failing to circulate correctly through the heating system, causing a rapid and unsafe temperature difference inside the unit.

Your boiler has shut down because the internal water temperature is rising much too quickly, which usually points to a blockage, trapped air, or a problem with water circulation.

Your boiler has detected that the flue gases are getting too hot or that a safety connection inside the unit has come loose, causing it to shut down to prevent damage.

Your boiler is failing to light the flame needed to produce heat and hot water, which typically indicates a problem with the gas supply or the ignition components.

Your boiler has stopped working because it cannot keep its internal flame lit, which means it is unable to produce heat or hot water.

Your boiler has detected that the internal fan responsible for moving air is not spinning at the correct speed or is being held back by a loose connection.

Your boiler's communication system is experiencing an electrical issue, which is likely preventing it from receiving the signal to turn on your heating or hot water.

Your boiler has detected an electrical fault within the internal component that controls the gas supply, meaning it has safely shut itself down to prevent any risk.

Your boiler's internal computer is experiencing a memory error, meaning it has lost its settings and cannot safely manage the heating process.

Your boiler has detected a faulty signal from its internal sensors, which means it cannot accurately measure the temperature of the water flowing through it and has safely shut down to prevent damage.

Your boiler's computer system is getting too hot and has automatically shut down to prevent permanent damage.

Your boiler has detected an internal error with its computer chip that processes the flame safety signal, which means it has safely shut down to prevent unsafe operation.

Your boiler is struggling to keep the flame lit reliably because it is having trouble accessing or processing its fuel supply properly.

Your boiler has lost its identity settings, usually because a part was recently replaced and not correctly programmed to match your specific model.

Your boiler is confused because it is getting incorrect information about how hot the water is inside the system, so it has stopped working as a safety precaution.

Your boiler has detected that the water temperature is behaving unexpectedly, suggesting that its internal heat sensors are likely providing conflicting or inaccurate information.

Your boiler's internal sensor that measures water pressure is malfunctioning or disconnected, preventing the system from knowing if it is safe to fire up.

Your boiler has noticed that the water pressure sensor is not detecting the expected pressure spike when the pump starts up.

Your boiler is failing to detect a rise in water temperature when the flame ignites, which usually means there is air trapped inside or not enough water circulating through the system.

Your boiler has detected a mix-up or incorrect reading between its internal temperature sensors, which usually means they were installed backwards or have come loose during maintenance.

Your boiler has detected that its internal temperature sensors are either disconnected or have been accidentally moved to the wrong pipes during installation or maintenance work.

Your boiler is failing to detect the internal spark needed to ignite the flame, meaning it cannot start up to provide heat or hot water.

Your boiler has lost its connection to the component that controls the gas supply, meaning it cannot safely ignite to provide heating or hot water.

Your boiler has detected that the internal pump, which moves water around your heating system, is not communicating correctly with the main control board.

Your boiler's internal computer has failed its own safety check and can no longer control the heating system, meaning the unit will not operate.
