These machines have too many controls. My washer always runs on the same setting (I occasionally press the ECO button). Admittedly, most of my clothes are cotton or similar. When I had a dishwasher it was similar, but with a digital console. I used to just press "Wash". Of course, the controller board that makes all those options available is often the first thing to fail.

There's about a dozen settings on the washer's wash-cycle dial, and two rows of buttons. I don't know what they're all for. It's nuts - there must be about 40 combinations.
