Technical description

Ignition fault. Boiler has attempted to light 5 times and failed.

What causes this fault?

This fault occurs when the boiler cannot successfully create or detect a flame after several attempts. The most common reasons include a lack of gas reaching the unit, a worn-out ignition spark, or a sensor that can no longer confirm the flame is safely lit.

This fault is more common in winter, as frozen condensate pipes can back up and prevent the boiler from igniting properly.

Engineer required
