Yay! for the new dishwasher and a handy brother to install it! My new DW from 2021 runs for 4 hours and 21 minutes! I'm sure there is a speedier cycle, but "normal" doesn't seem to clean everything every time, and if I don't use "extended dry", something is still yet. So yeah, over 4 hours it is. I tend to run it late in the evening or early in the morning. I hope you enjoy yours!
