I will say this
In my opinion, the very best dishwashers ever made were the one wash arm Kitchen Aids with only one wash arm the 50 plus gallons a minute that pump circulated would blast off absolutely anything, a KDS 17 is pure perfection, and NOTHING dries dishes as well, total water usage is around 14 gallons a cycle and its done in less than a hour.I have put pyrex dishes with burned on baked beans and it came out clean with no scraping.Pay no attention to those who say the top rack wont get clean, as long as you dont place large pans in the bottom, the top will clean because if yo open the door the water will fly over your head and onto the ceiling,
