i regret buying this samsung dishwasher so much. it does a horrible job cleaning the dishes, no matter how sparsely the unit is loaded. all the parts are plastic, and things like the spray arms tend to fall off without provocation. the 3rd rack is totally useless.  although everything comes out with small food particles on the main two racks, the 3rd rack must just sprinkle on the utensils there... because the little bit of soft butter on that knife is still soft and hasn't budged after this machine finishes it's ridiculous 2-3 hour wash cycle.
