My combination boiler was working fine untill the other day.
l turned the water off by the main stopcock to put isolating valves on the hot and cold copper pipes in the bathroom, when l had done this l turned the water back on by the stopcock in the kitchen but since then l have no hot water or c/heating.
The boiler does not fire up and there is no pressure at all, what could it be.
