Mend Glowworm 30sxi Boiler Pcb Fault

How can I fix my Glow.worm 30sxi?

F13 flashes up on the display indicating a 'main PCB connection fault.' The service engineer fiddled with the connections and everything worked ok for three days before going wrong again. My son checked the connections this time with the same result. Does anybody know if there is a common fault with the connections or will I need a new electronics board?

could be a fault with the pcb or the wiring harness, there is a modified pcb for this boiler, but it depends how old yours is whether it'll already have it.
