This type of comment is common, unfortunately. It amounts to "Don't use [thing] because of [anecdote]".

Bosch, in particular, is highly regarded. They also have a wide range. I bought an 800 series 2-3 years ago. I went online to see if anything had changed. You still find the same options: front controls, top controls, different finishes, etc. You can still absolutely buy a dishwasher with manual controls. They're excellent products.

Now my model seems to be before Wifi was added although I did buy an LG washer and dryer that has Wifi, which I did actually try and set up and failed. The code and stack in these things is truly awful. AFAICT I couldn't get it to work because my home network is segmented with 2 Wifi access points. Each of them broadcasts my Wifi network on the same SSID with the same credentials so devices use whichever one has the best signal. It doesn't always move routers so it's not as good as, say, a Ubiquiti network, but it's good enough.

Anyway, the washer/dryer listed my Wifi network 3 times and failed to connect to it for reasons I never established. The error message was a generic "authorization failed". I think it might've had something to do with DHCP. Possibly my address range or DNS servers. Weirdly, it would connect via a phone hotspot just fine. In the end I gave up.

But the point is that the washer/dryer work just fine without Wifi and although I don't have a Wifi-enabled Bosch dishwasher, I very much suspect they do too. Your comment says "it needs to use their website for some functions". What functions, exactly? Would that be notifications for when a load is done? If so, that makes perfect sense. But I bet the dishwasher worked just fine without Wifi.
