Hi all,
I have a 2 1/2 year old biasi Riva plus HE 28kw, have started to get a problem with the hot water supply, turn on hot tap boiler does not light up, on checking the indicator lamops, they are flashing side to side like they are supposed to but are also flickering, if i turn on the CH then the boiler lights and then the hot water also starts to work, cant find anything in the manual, anyone have any ideas. Many thanks.
