BoilerFaultCodesYour boiler has tried to light itself but failed, meaning it has temporarily shut down for safety and won't provide heating or hot water.
Book a Gas Safe engineer within 24–48 hours. Your boiler may be unsafe or could break down completely if left.
Technical description: Ignition control circuit lockout. Boiler fails to light during the ignition attempt period (10 secs approx.).
What causes this fault?
This fault occurs when the boiler fails to detect a flame after several attempts to start up. The most common reasons include a lack of gas reaching the unit, a worn-out ignition spark electrode, or a faulty gas valve that isn't opening correctly. It essentially means the boiler is trying to light itself, but for one of these reasons, the fire simply won't catch.
This fault can be more common during the first cold snap of autumn when internal components like the gas valve may stick after being used less frequently over the summer.
DIY fix possible
Check if other gas appliances, like a cooker, are working to ensure gas is reaching the property.Turn the mode selector dial to the 'OFF/RESET' position, wait for five seconds, then turn it back to the original position.If it is freezing outside, check that your white plastic condensate pipe has not frozen solid.
