i have heating no problem, but now iwant it off. i get no hot water. when i open the tap the boiler doesnt fire. the led is supposed to go from central heating icon to dhw icon but doesnt move, i think i can hear the flue fan. help!!!
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
