You will be unlikely to get one - service agents may have them but the manufacturer will not want users messing around in the machines and electrocuting themselves. They will restrict access to schematics to prevent legal action against them.
You will be better placed to ask a specific question about the wiring - no guarantee that you'll get an answer but more chance than waiting for a wiring diagram.
Good luck...
