Sadly, I don't think dishwashers will last 20 years any more. Since 2005, I'm on my third dishwasher. The first one lasted 9 years, the second one around 5 (with one under warranty repair). At some point the repairs/parts cost more than what the original dishwasher is worth. Regarding the algorithm, I'm not sure they make a huge difference anyways. FWIW, The Technology Connections channel on YouTube has a couple of pretty interesting videos on how dishwashers work and how to get the most out of them: https://www.youtube.com/watch?v=_rBO8neWw04 https://www.youtube.com/watch?v=_rBO8neWw04 https://www.youtube.com/watch?v=Ll6-eGDpimU https://www.youtube.com/watch?v=Ll6-eGDpimU
