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
