I'm having trouble finding a decent diagram of how the diverter valve
works in a combi boiler.

I am assuming that there are two completely separate water flows through
the heat exchanger, only one of which is active.

The heating circuit water must be kept completely separate from the hot
water taps otherwise the chemicals in the central heating circuit would
leak out of the hot water taps over time.

However I can't find a diagram to show the complete flow.

I am mainly hitting descriptions of problems when the valve is faulty.

Have you tried Googling for a manual for your particular model? It will
probably be easier to identify the parts and the flow route from this.

This is the first hit that I get on a generic search
