Hello all,

I had no hot water yesterday and I indentified it as a diaphram problem.  I changed the diaphram, now I have. However it appears that the temp rises quickly to 80, eventhough the temp dial is set half way. The burner lights as normal and then cuts out for a couple of seconds then relights. This changes the temp from the taps. It seems to do this cycle as long as the taps are open. I have not noticed any warnings on the panel, all seems normal . CH is working as normal HELP!!!!

Will I be able to do this myself ? It seems really awkward to get to as its at the back of the boiler. What is the best way to clean it

many thanks


thanks
