I'm sure it was just a lemon, but we had a Whirlpool Gold Quiet Partner IV, a $900 dishwasher when we bought it, and it broke 5 times under warranty before they finally agreed to replace it. Since it was not in stock when this happened, we ended up getting a $1300 Kitchen Aid to replace it. The difference is astounding. They both had stainless interiors with grinders and they both got our dishes clean, but the Kitchen Aid is so much quiter and takes much less time to run a regular cycle. So far, so good. It saves us a ton of time. I didn't rinse dishes with either, though at this point couldn't in good faith recommend the Whirlpool based on our poor experience with reliability.
