This dishwasher only cleans well if you use every function available and make sure they are on the highest setting. The design is poor as well as you are unable to put long utensils or knives in the storage tray present to hold them upright as the top rack's wand will run into them. You have to lay longer utensils or knives flat on the 1st or 2nd shelf to get them cleaned in this dishwasher. If I could return it I would but we unfortunately were given the dishwasher as our option through our home warranty.
