Its the changeover valve. It can sometimes be repaired by replacing the rubber diaphram on the end. The Biasi one fits ok and is available off the shelf. Otherwise you have to replace the valve and that is more of a prob as I cannot get this part at the moment. If you find one let me know. Ian. tcpc@ntlworld.com

i filled the central heating up to 2 bar and the dhw now works!
