Hi, is the water flowing from the boiler towards the radiators getting very hot at the point when the boiler halts, or does it remain cool.

I think its a common fault with this model. I had the main board replaced twice for this fault.

Before you spend a lot on new PCBs I suggest you engage a competent boiler engineer to correctly diagnose the fault for you.

I have not seen your boiler but the PCB is the last thing I would suspect.
