BoilerFaultCodesTechnical description
Average ignition times
What causes this fault?
This issue occurs when the boiler's control board detects that the burner is taking a few seconds longer than normal to establish a stable flame. The most common reasons are worn-out spark electrodes that can no longer create a strong spark or a build-up of carbon deposits on the sensing probe which prevents it from 'seeing' the flame quickly.
