But you said in your first post that you had already changed the PCB? Have you changed it or not?

don't know about you tony but i think the op has spent a lot of brass for nothing
Even if he has changed them himself ( whilst unregistered for gas work and endangering his family and neighbours ) then the retail price of the parts is probably about £200.
As its not the gas valve or the PCB a competent RGI will probably find its a simple problem and fix it for £50-£90 !
Many faults are simple and cheaper to have them fixed by a professional than blindly changing expensive parts.
