my default dishwasher is always Bosch, not the best but half the price of Miele, Built much like Miele in design.
Bosch is not perfect, but it is quiet, reliable and cleans. What else do you want for $800.00?
forget anything Electrolux, Frigidaire, LG, Samsung they are not very good at making Dishwashers.
Who is left? GE and Whirlpool Products
GE excels at price points 300 - 600. range and really you do not want to spend more than that on a GE. as soon as you decide to spend less than say 400.00
there are not many quality machines left.
KItchenaid price points hang right there with Bosch, so it is a you pick em, but Bosch washes better.
Whirlpool is a de-featured Kitchenaid designed to compete at lower price points.
Kenmore is a freak product in the fact you never really know what you are buying. Frigidaire? LG? Samsung? Whirlpool? stay away there is a reason Sears is heading to the toilet.
I hope this helps
