IIRC the Miele 48XX series are not built in Germany but one of their plants in Eastern Europe or elsewhere. For whatever reason our Miele dealer and others have reported potential buyers felt the German made 30XX series were of better build quality and usually went with those units.
Then there is the fact that Miele went up against Whirlpool and other long established washers that not only offer the same or better capacity, but cost less, much less. Most American households aren't thrilled with spending >1K USD for a washing machine, and quite honestly aside from the honeycomb drum and a few other gee-whiz type options the Miele didn't offer them much else. Then there is the fact that Miele still has a rather small distirbution/repair network. If one lives in the metro NYC,LA,SF or other upscale urban areas chances are Miele will get a service tech out within <five days or so, however if you are living on a farm in Kansas all bets are off.
Regarding programming of modern Miele units: Apparently Miele's customer service research found that Amercians felt some of their appliances offered *too many* options and or were confusing to operate. Remember by and large Amercians are used to top loading washers with one or perhaps two choices to make besides cycle selection. The idea of having to chose from an vast menu put some off.
Mind you on many Miele washers the options are still there, just buried deep in the programming. They are turned on or off depending how the machine is programmed at the factory for it's ultimate destination.
