I'm on the fourth KA in about 40 years. Each is better than the previous. Present one is four years now, not a problem and the only less than perfect dish was a couple of times they were not loaded properly and water could not get to the surface. Only rinsing is a quick psst under the water to get big stuff off, or if it is not going to run right away to get any potential smelly stuff off.
Never had a dog hair clog either.
