As machine was never sold in North America Miele North America (USA, Canada, and Mexico) likely have no information other than what can be pulled up in their systems. It is likely certain you won't find a tech or customer support person who even knows what this machine is much less ever worked on one.
Sometimes you luck out and get an old school tech or support person who is up for the challenge and will work things out, others cannot and will not be bothered.
Last time one inquired to Miele about appliances brought here from Europe, but never sold on this side of pond response was "Miele will provide worldwide support for their products, but if you want repair work done it is not guaranteed or carries any sort of warranty".
This can understand as it is a bit much to ask people to fix a machine they've never clapped eyes upon. That being said usually there are only subtle differences between what is offered in North America and Miele appliances say in Germany.
In general however Miele North America is washing their hands of appliances that are thirty or so years old. They no longer import parts for W700, W1070, W1065, and even some early W19XX series washing machines. Good luck getting a tech that even knows what these early machines are. Miele stopped training new techs on "older" appliances years ago.
It looks as if your washer was hardwired, something common enough in Europe, but on this side of pond we are used to plugs already on cords. You might want to consult a qualified electrician to assist sorting out how to either put a plug on this washer or how to hard wire it into what you've got.
While assume it is possible but haven't heard of a washer that would only run on say 240v, but not 208v or 220v. Looking at Miele washer internal parts and or electrical plates normally they read "208v-240v" power range.
