We have an issue with the boiler where it seems we now have to switch the boiler off at the mains and back on again to get it to fire with the central heating but it will fire every time with hot water.
It will fire at all on the Auto timer and will only fire once if in the ON position for the heating. Once we turn the heating off we have to turn the boiler on and off again at the mains to get it to fire with the heating back again.
Any ideas what could be the issue?
