BoilerFaultCodesTechnical description
The boiler is in heating mode
What causes this fault?
This is not actually a fault, but rather a status code indicating that the boiler has received a request for warmth from your thermostat. It means the internal pump and burner are active and are successfully sending hot water to your radiators. You will see this code whenever the heating is running as intended.
This code is most frequently seen during the autumn and winter months when the central heating is programmed to run more often.
DIY fix possible
No action is required as this is an status indicator, not a fault.Check your thermostat settings if you did not expect the heating to be on.Monitor the display to ensure it changes when heating is no longer required.
