HI, can anyone help, I have a Biasi M90f24S combi boiler and over the last month having problems with the hot water going hot and cold. No problems with the central heating side, but cannot get the hot water to run consistantly.
Have tried running another tap along with the shower, but no change. Rang a local plumber but they never returned my call.
