I am in the market for one as well. Mine is a KA, 33 years old, runs fine but is just
worn out inside, and I would really like a food disposal in it (wasn't around way back then). For my first home I bought a portable KA, I've had a Whirlpool that ran perfectly for 20 years in my seasonal home, and got a Maytag for my office. All of them gave me no trouble.
I asked 2 repairmen about dishwashers. One said that when Whirlpool took over KA, it agreed to maintain the very high standard of the KA dishwasher that was started by Hobart when KA took it over, regardless of the other Whirpool appliances. Another said he wouldn't buy anything but KA. I asked him specifically about Miele and how they are loved in Europe. He insisted that it was because KA isn't readily available there and that they are not as good here.
I've decided on the 3-rack model with the cutlery level but with the indicators on the outside of the door. I take a long time to make such decisions as I have had nothing but ideal experiences with my appliances.
