Bought it and installed it mid Dec 2014. Since day one the bottom rack does not wash the dishes as I would expect from a Miehle. About 1/2 the time we run the unit, about 5% of the bowls or dishes on the bottom shelf don't clean well enough, so we have to wash those pieces again.
We have tried different placements of the dishes, but no change.
Just disappointing. I don't remember having that problem with my Bosch.
