my combi has recently stopped producing hw. water flows, but the boiler doesn't fire up when i open a hw tap. however, the ch is fine!
it's been suggested that i probably need a new diaphragm and it looks like this will cost me about 200 quid to get fitted. however, i've searched other posts on here and it seems like this should (in theory at least) be a fairly simple job which i may be able to do myself.
as such, can anyone confirm if this is sth i can do myself - i have v little knowledge of boilers - and, if so, how exactly do i do it?
cheers.
