would they be getting hot water only if the heating is on if the diaphragm is split or needs remewed ?
ssupposse it makes sense, the hot water going through the diaphragm when the heating mode is on.

if the diaphragm is stretched it will only open halfway and not hit the endswitch. if the heating is on they get hot water, if it's not they don't. the diverter could be sticking and providing the same problem.
hot water doesn't go through the diaphragm, the cold mains only passes through it to provide a method of seeing demand.
