That's an enviable efficiency as far as water use is concerned, but...

In the US according to a quick web search, a full sized Miele dishwasher can
run from $1,249 to $2,149 depending on the model. A more typical dishwasher
costs $300-$400, making the Miele over five times as expensive. That
difference will buy an awful lot of water - in my area, about 849,000 US
gallons (3,213,814 liters). Even if the cheaper dishwasher used 10 gallons
a load, if the thing was run once a day, it would take 232 years for the
water savings to break even on the additional cost, not counting the expense
of heating the additional water and assuming water costs don't go up.

If that's all that was available I'd buy it, but in the face of cheaper
alternatives, it just isn't worth it on purely economic terms.
