Shipping is very dear from Germany
Case in point a few years back won an auction for NOS barrel of Ariel detergent powder. Seller was in Germany and the only bid was mine and came to < 10 Euros. Shipping that barrel of detergent was quoted at > 40 Euros. Like vintage detergent as much as the next collector, but not that much. Seller agreed the amount was excessive and let me out of the deal.
You aren't going to get anything large as a washer or dryer out of Germany easily nor cheaply.
Remember air has largely replaced transit by shipping for parcels and mail. Thus size and weight matter a lot. Something like an appliance would have to be packed and crated properly, then a method of shipping determined. You *can* elect to try air but that again is going to be costly.
Next option would be a air freight service. I mean people do ship BMW's, Audi's and other German automobiles to the USA so anything is possible.
Have always maintained all these wonderful European appliances many of us have found in North American came over when someone moved house and either came by ship (not to uncommon right through the 1960's), or someone else was picking up the tab like military or employer.
Found much of this out when my beloved Pfaff ironer was broken a few years ago. Seriously researched having another sent from Germany. Mangles and ironers are a dime a dozen in that country with persons literally giving them away. Shipping to USA? Nope, not going to happen.
Now Miele USA does have "marine" division where you can purchase a top loading H-Axis washer. See:

However the thing is rated for 230v/50hz and they will under no circumstances sell to domestic users.
The only dealers are in Florida and you are more than welcome to try if interested. I couldn't get a foot past the front door nor would bended knee get them to budge on that policy.
