I bought replaced my very old dishwasher with a Whirlpool dishwasher about 9 years ago. I bought what I could afford that had the features that I wanted. I live alone so the dishwasher gets run about every 4-5 days. I do not rinse unless there are large pieces of food, so dishes sit with dried oatmeal and other assorted food residue on them. I use Walmart brand of dishwasher powder and the high temperature wash every time (I do not dry) and my dishes come out clean every time.
