Atag Premier Fault codes & diagnostics

Your boiler has detected that the water pressure inside your heating system is too low, meaning it needs to be topped up with more water to work correctly.

Your boiler has stopped working because an external safety device, such as a frost thermostat or a cylinder cut-off, has sent a signal that it needs to shut the system down.

Your boiler has automatically paused itself because the exhaust gases getting rid of the fumes have become dangerously hot.

Your boiler has detected a faulty reading from a safety sensor in the exhaust system and has stopped working to prevent any potential damage.

Your boiler is pausing because it cannot detect water moving through the system, so it is running an automatic process to clear trapped air before retrying.

Your boiler is confused because two temperature sensors have been incorrectly identified or swapped, preventing it from safely heating your water.

Your boiler has detected that the temperature sensors monitoring the water flow have been installed in the wrong positions or are providing conflicting information.

Your boiler has detected that the water trap responsible for disposing of condensation is potentially blocked or not draining correctly, causing it to shut down to prevent internal water damage.

Your boiler is struggling to detect the movement of water inside the system, which is preventing it from heating your radiators or hot water properly.

Your boiler is struggling to accurately measure the temperature of the water returning to it, which causes it to stop operating to prevent potential damage.

Your boiler is struggling to detect the flow of water because a sensor is failing, which means it has stopped heating your home or water to prevent internal damage.

Your boiler is struggling to accurately measure the temperature of the water returning to it, so it has stopped operating to prevent potential overheating.

Your boiler has detected a communication issue with the sensor that monitors exhaust gases and has safely shut down to prevent potential overheating or unsafe operation.

Your boiler has detected an issue with the internal fan responsible for safely venting combustion gases, so it has stopped working to prevent unsafe operation.

Your boiler has detected that the water pressure inside the system is too low for it to operate safely.

Your boiler's internal computer has encountered a critical error and can no longer safely manage its operations, meaning the system will have shut down to prevent further damage.

Your boiler's computer has detected an internal error and has shut itself down as a precaution to prevent further issues.

Your boiler is failing to light because it cannot detect a flame, meaning you currently have no heating or hot water.

Your boiler's electronic brain has detected an internal communication error and has safely shut down to prevent incorrect operation.

Your boiler’s internal computer is experiencing a communication error or software glitch, preventing it from starting up correctly.

Your boiler's computer is experiencing an internal error and cannot safely operate your heating or hot water systems.

Your boiler has shut down because the water inside is significantly hotter than it should be, which could indicate a circulation problem.

Your boiler has detected that the water returning from your radiators is dangerously hot, causing the system to shut down to prevent damage.

Your boiler has stopped working because it cannot properly clear exhaust gases, which is a key safety feature to prevent fumes from building up.

Your boiler is struggling to light correctly or stay lit, which means the system has safely shut itself down to prevent any issues.

Your boiler has detected an electrical fault in its internal control system that is preventing it from operating safely.

Your boiler is trying to start up but is failing to light the burner, meaning you currently have no heating or hot water.

Your boiler has detected that the internal components are getting too hot, so it has safely shut itself down to prevent any damage.

Your boiler has detected an issue with its electrical power supply or an internal electronic processing error.

Your boiler has detected an internal fault with its main electronic computer system, causing it to shut down for safety reasons.

Your boiler has stopped working because an internal electrical protection fuse has blown, cutting power to the control system.

Your boiler has detected that the water returning from your radiators is too hot, causing it to shut down to prevent damage.

Your boiler has stopped working because it cannot confirm that the internal fan, which is essential for safely venting combustion gases, is spinning correctly.

Your boiler has stopped working because the water pressure inside the system has dropped too low and needs to be topped up.

Your boiler has stopped working because the water pressure inside the system has become too high, which is a safety mechanism to prevent damage.
