i have heating but no hot water hot water works when boiler is in heating/hot water mode but not when in hot water only mode
central heating pressure gauge rises when hot tap is opened
As with most combi's the divertor valve is usually the source of problems with hot water. Its the same with yours. With the control panel down the divertor should be on the left facing you. It has a micro-switch fitted to it which is activated by a pin pushed out when the taps are turned on. Should be repairable with a service kit.
