240 combi RSF - No hot water but CH works. Can I mend it ?
Hello,
I have a 240 Combi RSF and very recently the hot water stopped being hot. When I run the hot water tab the "Demand" light remains off. The central heating is unaffected and hot water is supplied when the CH is on. Can I do anything to remedy this or is it best to call a corgi person.
