valliant turbomax 28e prob

[abz1234]

I need to know how you go about changing the diverter valve on this boiler. When I turn on hot water my heaters also start to get warm. Is changing it a easy job ? . Would I need to drain the system or do any other thing before removing the valve.

All the help much appreciated
