My Potterton Flamingo conventional flue boiler fires up when I select HW on the programmer but then goes off after about a minute. It won't then fire up for ages (presumably until the water in the boiler has cooled).
If I select CH instead, the boiler won't fire up at all.
Is this likely to be a boiler problem or could it be the pump (or something else)? I can imagine that if the pump is not circulating, the water in the boiler would get hot and switch itself off, but would it stop the boiler firing up at all, as it does when CH is selected.
