Mend Glow-worm Maxi 105e Heating Hot Water PCB

How can I fix my Maxi 105e?

When I switch on to heating and Hot water (CH & HW)
The supply light is on, The CH &HW light is on.The Pump runs. The fan kicks in but cuts out straight away, kicks in again and stops again, and then the fan warning light starts to flash. and thats it.I have replaced the PCB.

looks like you wasted your money, it looks like the pressure switch isnt making contact, which in turn doesnt send signal to fan to stay on. This would be first thing to check ,then if that is ok it has to be the fan itself,look for scorching etc on coil on fan.
one more thing ,its actually illegal to work on boilers if your not Gas Safe, so wot ye doing anyway!! im only telling you how to fix it because i feel pity 4 u
