I have a pro combi he 85 and recently the hot water has stopped working, I've had a look at it and found that the central heating heats up when I run the hot water as I'd the diverter valve is stuck open even when the mode selection is just on hot water the central heating heats up, the hot water does get hot once the ch temp is up, I'm thinking it's the diverter valve but somemore insight would be helpful[/img]
