Chaffoteaux MX2 24FF Misfiring Safety Feature?

I have a Chaffoteaux MX2 24FF combi boiler that keeps tripping off and the fault code indicates a 'misfiring safety feature'. I've tried a new PCB and new igniter electrodes, it'll work for a bit and then the same fault occurs. Sometimes it'll reset and most of the time it won't. Any ideas because I fear an expensive boiler replacement on the horizon!!
