this dishwasher constantly leaves food particles on most dishes, even if it's loaded carefully. there is no water power to get the job done and you can tell water doesn't find the tighter spaces. if you half load it, you might get all dishes clean, without food left over on them. the racks are very inflexible in how you can load them. it's difficult not to sound too over-the-top, but when you spend so much on a major appliance, you expect a certain level of performance. i spent two months trying to get this thing to clean, now i can't exchange it at the big box store i purchased it from. what say you samsung? do you have enough integrity to refund my purchase?
