Technical description: This indicates the boiler has failed to light
What causes this fault?
This fault occurs when the boiler attempts to start up but cannot successfully establish or detect a steady flame. The most common reasons include a lack of gas reaching the burner, a worn-out ignition spark, or a buildup of carbon on the sensor that tells the boiler it is safe to stay lit.
This issue can be more frequent during the first cold snap of winter when internal components like the gas valve may stick after being idle during the summer months.
DIY fix possible
Check if other gas appliances, like a cooker, are working to ensure gas is reaching the property.Ensure your pre-payment gas meter has sufficient credit.Press the 'Reset' button (often marked with a flame symbol) on the boiler control panel.
