Product review (2 stars): If we had it to do over again, we'd have gone with a Bosch.
We recently bought the Architect Series Top Control Dishwasher after our Bosch machine finally gave up the ghost.  We did a lot of shopping before settling on this machine, and really were torn on whether to go with Kitchen Aid or another Bosch.  We absolutely loved the Bosch, but had also had good luck before we bought it with an earlier Kitchen Aid dishwasher.  Given our prior good experience with Kitchen Aid, a real good price on the new one, and the fact that Kitchen Aid has heated drying whereas the Bosch does not, we went with the Kitchen Aid.

We soon found out that, whereas we could put heavily soiled dishes in the Bosch and they would come out clean as a whistle, we have to thoroughly rinse the dishes before washing in the Kitchen Aid or else they come out with food particles dried and stuck like glue to them.  The other thing about the new machine we don't like very much is the stainless steel front panel.  We have a top of the line Frigidaire gas range in stainless that has never in nearly 5 years of use shown fingerprints due to special surface treatment.  Since Frigidaire owns Kitchen Aid, we assumed their top of the line dishwashers would also be resistant to fingerprints.  Not so!  Anything that touches the front - either a finger, and hand, your knee, a towel - whatever - leaves a mark or a smudge that can only be removed with stainless steel cleaner and a microfiber cloth.

Additionally, the silverware basket in the Bosch could be left in its normal side of basket location, or could be moved to the front of the bottom basket, or could even be put in the top basket, which made creative loading much easier.  With the Kitchen Aid, the HUGE silverware basket can only be in the one original place at the side of the bottom basket, and pretty much takes up that whole side of the basket.

Our Bosch had a soft food disposal built in and worked like a champ with only having to clean the screen at long intervals (almost never).
The Kitchen Aid filter screen gets completely clogged up within a week (even with pre-rinsing the dishes) and has to be removed and scrubbed clean weekly with a brush and running water.  If we omit this chore, we start getting a food particle film on everything.  (Kinda makes one wonder about the rinsing efficiency of the machine.)

As far as malfunctions go, we have had none to-date (knock on wood.)  But then we only have about 4 months of usage on it.

Bottom line is, we have more or less made our peace with it, and it does seem to be marginally better in some ways than your basic cheap builder's special dishwasher.  But rest assured, when it comes time for another replacement, we will return to and likely stay with Bosch.
