Your boiler is working normally and is currently either providing heat or ready to fire up when needed.
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: Appliance is ok
What causes this fault?
This is actually the normal operating state of your boiler and does not indicate a breakdown or failure. The light is triggered by the boiler receiving a signal to provide heating or hot water, or it simply indicates that the system is in standby mode and ready to work. There is no physical fault present; the internal components are simply communicating that they are powered and functioning as intended.
DIY fix possible
No action required as the boiler is performing its normal functions.If the LED is flashing green, it may be in standby mode or a temporary 'purge' cycle.Ensure your thermostat is set to the desired temperature if you want the heating to turn on.
