What causes this fault?
This is not a fault but a status message indicating that your boiler is working exactly as it should. It appears when the system detects a demand for warmth from your thermostat and has fired up to circulate hot water to your radiators. You do not need to take any action while this code is displayed.
This code is most frequently seen during autumn and winter when the central heating is switched on regularly to combat the colder weather.
