BoilerFaultCodesThis light simply shows that your boiler is receiving electrical power and is switched on.
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: Illuminates to indicate that the electricity supply is turned on.
What causes this fault?
This is a normal status indicator rather than a fault, confirming that the internal control board is receiving 230v mains electricity. If this light is off, it usually means the boiler has blown a fuse, the external isolation switch is turned off, or there is a failure in the local power supply. As long as this light is glowing, the boiler has the electrical power it needs to begin the ignition sequence.
DIY fix possible
Ensure the main power switch for the boiler is in the 'ON' positionCheck that the fuse in the spur hasn't blown if the light fails to illuminateMonitor the boiler for normal operation as this light indicates standard power status
