Technical description: Boiler in ignition mode
What causes this fault?
This fault occurs when the boiler attempts to start up but cannot successfully establish a flame after several attempts. The most common reasons are a lack of gas reaching the burner, a build-up of soot on the ignition sensors, or a failure in the electrical component that generates the spark.
This issue is more frequent during the first cold snap of autumn when boilers are switched back on after being idle for several months, often revealing sticking gas valves or worn electrodes.
