I had my boiler fitted about 3yrs ago now and last night the hot water stopped working, my partner ran herself a bath but then when i tried to run mine, nothing, the boiler is not even firing up. Have rang a friend who thinks it sounds like the diverter valve, does thi sound correct? If anyone knows would be huge help as have had alot of bad luck with registered plumbers in the past and dont want to keep spending dead money. The CH is working fine as normal.
