Technical description: Ignition fault or no gas supply
What causes this fault?
This fault occurs when the boiler attempts to start but fails to detect a flame after several attempts. The most common reason is a temporary interruption in the gas supply or a build-up of carbon and wear on the components that generate the ignition spark.
This fault is slightly more common during the first cold snap of autumn when internal components that have been idle all summer are suddenly forced to work under high demand.
DIY fix possible
Check if other gas appliances (like a cooker) are working to confirm gas is reaching the property.Ensure your gas meter has credit if you use a top-up card.Press the reset button on the boiler control panel to see if it restarts.
