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.
