I have a Biasi Riva Compact M90E.24S combination boiler.
The central heating works fine but since last week only very cold water comes out of the taps. The strange thing is that when I turn on the DHW taps the bolier does fire up, but only cold water comes out of the taps and the hot water flows into the central heating side instead.
Any ideas?
