You put dishes into the dishwasher, it makes a lot of noise and then you take clean dishes out. Unless you didn't rinse something well, but that is a different discussion. Ever wonder what actually goes on inside there? Me neither but I saw this video and had to watch. I thought high powered jets shoot out scrubbing the dishes within an inch of their life. What really happens is actually kind of a relaxing sprinkle. Take a look and relax.
