BoilerFaultCodesYour boiler is working normally and currently heating your radiators or hot water.
This is a minor fault. Keep an eye on it and mention it at your next annual boiler service. Reset the boiler and see if it clears.
Technical description: The boiler is operating for central heating / hot water
What causes this fault?
This is not actually a fault code, but a status indicator showing that your boiler is performing its main job. The 'C' indicates that the boiler has received a request for heat and the burner light confirms that a flame is present to heat the water. It simply means your system is functioning exactly as it should be to keep your home warm.
This code is most visible during autumn and winter when your thermostat is frequently calling for the heating to stay on.
DIY fix possible
No action is required as this is a status indicator rather than a fault.Check your thermostat settings if the heating is on when you do not want it to be.
