I dont agree with your conclusions except that the fan mod PCB is a design problem.
It should have been replaced before with a revised design which is not expected to fail. Perhaps the original type was fitted.
We have only concluded what your boiler's fault is and thats based only on what you have told us and not on any visits to investigate the problem.
