I remember the Maytag dinner where they introduced this dishwasher. John said that they now had it half right. I have a convertible portable of this machine with the white on white control panel. It is an excellent cleaning machine, however, gallon iced tea pitchers block water to the upper rack so you have to put things above them like shallow bowls and pot lids that can be washed by the wash arm in the top of the tank. Most of what they say about the soil separation system in the WP-made machines is BS. The regular cycle on the Maytag has the same number of water changes as the WP/KM Ultrawash. For the types of loads I put in the machine, the WP/KM Ultrawash holds more than the Maytag, Neither holds as much as my 18s, but for real scrubbing, they both outshine the 18. Of course the 18s are 34 years old and these machines are newer. One thing I really love about them is the timer dial. Last weekend I used my Farber broiler. Even though I sprayed the rack with Pam, it had some baked on stuff. Rather than running the whole load through a Pot Smasher cycle, I waited until the end of the wash cycle and then just turned the timer to repeat the wash (minus the fill). The rack came out perfectly clean. Speaking of the Farber, do any of you put water in the Farber's drip pan before using it? It really makes clean up easy.
What none of these comparative racking pictures has shown is that cookie sheets, quarter sheet cake pans and similarly shaped items can be easily loaded in the bottom rack of the 18 IF they are loaded so that they tilt slightly outward with the soild surface facing the side of the tank. There are holes toward the tips of the wash arm that scour things very effectively in that position. You make sure that you load a cookie sheet with a lip on one end so that the lip is at the front of the rack so that it does not scratch the porcelain as you move the rack. Deeper pans are loaded on the left side while cookie sheets and shallower pans are loaded in the more closely spaced pins on the right.
