I've used several different brands of dishwashers and the noise is always my biggest complaint. Samsung has done an amazing job with this dishwasher. It's soooo quiet. We waited to fill up the dishwasher to do that test vs hand washing as we've been doing. I'm glad we did. It was a great test to see how well it washed the dishes and how quiet it was. Well, after it ran I let it cool down before opening to check stuff. Let's just say it out performed. My boyfriend's mother was very happy nothing had spots on it and we have hard water too. She loved the top slide out to put other utensils on, but we did notice some didn't get as clean (so I'm assuming it due to being up there). So anything up there will have to be completely rinsed off prior to putting in the dishwasher. Other than that, we are very happy with the dishwasher and have no complaints.
