I have noticed that The831Bunny appears to be the man in the know regarding Vaillant Combi Boilers. If anyone is a "buddy" of the guy can you please get him to respond to this?
I have the old but brilliant VCW sine 18T3W. It is still in great condition but I now cannot get hot water. When I run the hot tap the centre spindle in the flow switch moves down to contact the micro switch on the RHS. The burners come on for a few seconds then cut out. The water is cold. The central heating appears to be fine.
Any help from other informed people would be most welcome.
