I have changed central heating flow sensor also hot water flow sensor. Also changed the 2 electrical boards all new.
The problem i am having is it will run for so long then will cutout and the boiler shutdown light comes on, I have to reset it again till it happens again. Can you tell me what to try next. Thanks
