What causes this fault?
This is a status code rather than a fault, indicating that the boiler has successfully ignited the burner and is operating as intended. It appears when the system detects a demand for heat and is actively burning gas to warm up your home or hot water. If this code is showing, it means the internal components are working correctly and no repair is needed.
DIY fix possible
No action is required as this is a status message rather than a fault code.Wait for the boiler to finish its current heating cycle.Check your room thermostat if you feel the house is getting too warm.
