My combi boiler sparks up burns for a short while and goes out. Hot water and central heating. Fan is running and clean. flu is clear. changed the venturis, changed the air prussure switch, changed pcb. changed overheat stat, changed the thermistors. Nobody can fix it. any ideas?

Has anyone checked the pump? Maybe the boiler is cutting out because the heated water is not being circulated away from the heat exchanger which is why it can burn for a short time.

pump runs ok and it's the hot water side playing up too. decided to scrap it and get a golw worm. lets hope i have more luck with that.
