Hey, Ben---
Thanks for going to the trouble to scan all this stuff.
Interesting reading. I have a DU600 I used for quite a while when I was living back home in Atlanta. I did not re-install it here in Roanoke.
It did a great job of washing dishes, however, I would take Maytag's advertising department to task about it's load capacity. I found it would not hold large bulky stock pots and my KAids will. Also, the KAids have the forced-air drying which is a feature that I really like.
I was amused that every single time the machine finnished a load, the spray arm was always in the exact same position, parallel to the front of the machine!
