Ravenheat Condensing Fanned Flue Boiler CSI Primary Problem?

There is no remedy!!!
I have a CSI 120 LOW NOX which intermitently fails on a code 14.
I have replaced the ignition control board ,potentiometers,DHW and CH sensors etc etc and I still have the problem.
The system was powerflushed before installation and again recently so a dirty system is certainly NOT a factor.
When the boiler actually works its certainly cheap to run and produces hot water quickly and in abundance but this code 14 fault is the bane of my life ANY IDEAS??

the boiler lights and then goes out and then lights and then goes out and so on - the rads do get hot and the domestic hot water is hot - but hearing the on off of the boiler is disconcerting

any answers

ps the boiler is only 2 years old

Problem now resolved, it was actually the ignition injector assembly, cost around £20, boiler working perfect.

Ok if you have the latest CSI primary, in the control box there will be two PCB's the small one is the fan ignintion board and that is what will require replacing.
