My brother's combi supplies CH fine, but he has no hot water whatsoever. Following the problem solving steps in the manual lead him to believe it could/probably be the diaphragm inside domestic water priority valve. However, the diagrams for the boiler don't show this part. They show something called the water valve and another called the hydraulic 3 way valve.

What do you plumbers reckon?
