Mend Glow-worm Hotwater Express 80 Boiler Heating Repair

problem with Glow-worm Hotwater Express 80 boiler?

hi there, my boiler will only heat water when it is set to Winter (heat plus water). im loathe to replace it altho it is probably about 10 years old - it copes with the heating just fine and i cant believe there is anything serious wrong with it but as a girl living alone im scared id get ripped off by rogue tradesmen - does anyone have any advice, is this a common problem and how might it reasonably be fixed?
thanks!

I just realised you do have a combi boiler.... my guess is that you need a new diaphragm fitting to the water valve.

Hi Jo, unless you have a combi I doubt there is anything wrong with the boiler, do you have any electrically operated valves, (zone valves or 3 port diverter valve) also check to see if there is a thermostat on the hot water cylinder.
