There are multiple problems with this buyer, although I agree that his warning that features that can only be accessed via a (for now) free phone app is a potential future problem area. First of all, I don't know where he is shopping, but nobody rational seems to be selling the 800 model for $400 more than the 500 model he bought. The models are almost identical and the 800 is, based on what I saw, about $100 more. You're paying that money for a different type of drying and slightly less noise. Second, I've got news for him, but the 800 model also uses wi-fi and the exact same app and while he may think that he can just push a button on the 800 - if he had it - to do stuff he has to use the app for on the 500, well, maybe not. Why have the app at all if the buttons on the 800 can do everything without it? Maybe he's right, but this takes more research and he may just be guessing and thus may be wrong. And finally, what the hell is up with the 4 hours he spent to connect it? I changed my dishwasher a few years ago and paid Lowe's, who I bought it from, to connect it for me and take away the old one. The install guy had it working in maybe 15 minutes. Look, I can do some minor plumbing stuff at home, like I can change the guts of a toilet tank out on my own, and I'm not fast because I do that stuff when needed so I don't do it every day as my job, but crap, how the hell does it take 4 hours to install a dishwasher? I watched my install guy and he connected some hoses and one pipe and plugged it into an outlet. How long can that take?
