This model is from the series that was tested by placing a Big Mac in the lower rack and running it on the power scour cycle. When the last rinse drained, the door was opened and there was no trace of the food.
I have a slightly more deluxe version of an older WP dw that I am hanging on to because it, like the newer Maytag can be set to heat the main wash and final rinse water. If I wind up somewhere with water that is not hot enough for the KDS18s, I will have two machines that still wash well and heat water, not like these new machines that don't half wash, but don't make noise.
