Hello I occasionally get no domestic hot water upstairs but if I put the central heating on first then I get domestic hot water upstairs.
I can see the pin operating the domestic hot water microswitch as I suspected the diaphragm, could it still be the diaphragm. The domestic hot water downstairs is fine. I have ordered a new microswitch just to rule that out.

Thanks

Hello Agas, Sometimes with the hot water tap running upstairs and the central heating off I do not get hot water , yet when I switch on the central heating I do get hot water.
Downstairs hot water taps are ok regardless if the central heating is on or off.
Thanks
