Alpha 240XE Fault codes & diagnostics

Your boiler is failing to detect that you have turned on a hot water tap, so it is refusing to heat the water for you.

Your boiler is struggling to detect the flow of water, which is preventing it from safely heating your radiators or hot water.

Your boiler is struggling to circulate water properly because it has detected air trapped in the system or a build-up of blockages preventing the pump from working correctly.

Your boiler's internal thermometer is failing to send accurate signals, causing the system to stop operating to prevent damage.

Your boiler has automatically turned itself off because it has detected that its internal water temperature has become too hot for safe operation.

Your boiler is failing to ignite because it cannot receive or process the gas supply needed to produce a flame.

Your boiler is failing to light the central flame needed to provide your heating and hot water.

Your boiler is failing to light its internal starter flame, which is preventing the entire system from turning on and providing heating or hot water.

Your boiler has stopped working because it cannot detect that the flame is lit, so it has shut down as a safety precaution.

Your boiler has detected that the core part responsible for heating your water is failing to transfer heat properly, causing the system to shut down for safety.

Your boiler's internal air extraction system is failing, which prevents it from safely igniting and providing heating or hot water.

Your boiler is struggling to clear exhaust fumes safely, so it has turned itself off to prevent any risk.

Your boiler's air pressure sensor is detecting an issue with the airflow system which is stopping the boiler from igniting correctly.

Your boiler is struggling to detect that the water flow has been turned on, which prevents it from firing up to heat your home or provide hot water.

Your boiler is struggling to detect water flowing through the system properly, which is stopping your heating and hot water from working.

Your boiler has lost its connection to the power supply or the main control board has experienced a temporary communication error.

Your boiler has failed to ignite, which means it cannot provide any heating or hot water until the flame is established.

Your boiler's central heating temperature sensor has detected a fault, meaning the system cannot safely monitor the water temperature and has shut down as a precaution.

Your boiler has detected an internal communication error between the main control board and its sensors, meaning it cannot safely manage the heating process.

Your boiler has detected an electrical fault with the internal sensors or circuit board, preventing it from heating your water safely.

Your boiler has automatically turned itself off because it became too hot, acting as a safety precaution to prevent damage.

Your boiler has detected that it got too hot and has automatically shut itself down for safety, meaning your pilot light has gone out and needs to be relit.

Your boiler has become too hot and has shut itself down completely, including the pilot light, as a safety precaution.

Your boiler's pilot light is going out as soon as you let go of the control knob, meaning the burner cannot stay lit to provide heat.

Your boiler has detected an issue preventing it from keeping the flame lit, so it has safely shut itself down.

Your boiler has stopped working because it couldn't safely ignite its internal flame, so it has shut itself down to keep your home safe.

Your boiler is failing to receive a consistent electrical power supply, which means it cannot turn on or heat your water.

Your boiler is struggling to circulate water because the pump responsible for moving it around your system is not receiving the correct power, causing your heating and hot water to stop working.

Your boiler has stopped working because the water pressure inside the system has dropped too low or there is trapped air causing a blockage.

Your boiler has identified a technical fault affecting how it senses temperature or processes internal airflow, which has caused it to shut down to prevent damage.

Your boiler is struggling to clear exhaust gases properly, so it has safely shut itself down to prevent any risk.

Your boiler is failing to light the burner, meaning it cannot produce heat or hot water because of a potential electrical or sensor issue.

Your boiler is struggling to control how much heat it produces, which likely means it cannot sustain a steady temperature for your radiators or hot water.

Your boiler is failing to light the pilot flame, meaning it cannot start the heating or provide hot water.

Your boiler is failing to light the flame or stay lit, meaning it cannot produce heat or hot water because it cannot detect a flame.

Your boiler has detected that it is getting too hot and has automatically switched itself off to prevent damage.

Your boiler's reset button is failing to send the signal required to restart the system, meaning the unit cannot be woken up from its current locked state.

Your boiler is not receiving a signal to turn on, which is likely due to the timer settings or the thermostat connections not communicating correctly.
