... if you know the secret button sequence to break out of the menu.
I can't think of a good reason to have a network-connected dishwasher. I don't think I'd ever start it remotely, as I still have to clear the table and rinse the dishes. The washer gets started when I'm done loading it. I can check detergent levels while the door is open.
Pretty much the same for all my other appliance for that matter.

I did see the twitter screenshots, but as I don't own the device myself I couldn't really judge if the GP's instructions are readily apparent to the average user.
Also, I don't disagree with you. But the OP seemingly bought such a device and connected it to their wifi. Maybe they are living in a furnished apartment with pre-configured wifi? Anyway - thankfully we are not yet in an era where ones only choice is a connected dishwasher - can still buy used, older models etc.
edit: One would hope that you can factory reset the dishwasher to make it forget the wifi information, if it has been configured by someone else.
