in Wednesday, 5/5/10 Wall Street Journal. They mentioned dishwasher testing. They smear the dishes with disgusitng stuff, let them dry overnight then load them up in the morning, 113 pieces in each dw. Before any washing takes place, the machines are photographed to make sure that everything gets put in the same place for the next two washings. One of the flaws with their loading that I noticed from the 60s was that they do not load the machines with mixed loads of dishes, pans and bowls. They never noted which machines could wash stuff in the top rack if the lower rack was filled with pans and stuff that blocked water to the top rack and that was a real loading factor in most machines. It was always a consideration in our KDC15 which was still washing dishes when we pried and blasted mom out of the place in 2003.
