... the dishwasher.
That's my experience anyway. I moved into this house in 1986, the dishwasher died shortly after that. The replacement died and was replaced, and the replacement for the replacement died recently. The next one, getting installed right now, is this one.
Meanwhile, I have a washer and dryer that were installed in the late 80s that work (and look) like new and have never even needed repair. What brand? Same as that new dishwasher. If they ever die, I don't think I'll be able to replace them with something that works as well, not in these "energy efficient" times.
