Technical description: Boiler is active for central heating
What causes this fault?
This is not a fault but a status indicator showing that your boiler is operating exactly as it should. It appears when the internal controls have detected a request for heat from your thermostat and the burner has ignited to warm the water for your radiators. Once your home reaches the desired temperature, this code will change or disappear.
This code is most frequently seen during the autumn and winter months when your central heating is scheduled to run more often.
DIY fix possible
No action requiredAdjust your room thermostat if your home is too warmEnsure your radiator valves are open
