These all have a very simple job to do, and there’s absolutely zero value-add to the smart edge software nonsense.
It would make sense for a washing machine to be smart/have ai if it could detect clothes types and suggest a washing regime or warn you that selected regime can damage them. It'll also be nice to be able to schedule the washing so for ex. it's done when you get at home from work. For dishwasher - maybe somehow detect stuff that's incompatible with dishwasher and warn you?
I do also see a point in having a smart fridge that would detect products that expire based on some qr codes printed on them, otherwise idk...
Those examples seem like they would be useful for mentally disabled people. Not trying to be a dick here, but someone with declining cognitive abilities is more likely to put a sock in the dishwasher, to wash delicate clothing at 90 °C or to forget food in the fridge for months.
It reminds me of those items primarily designed for physically disabled people that (used to) be advertised for normal people on infomercials because the market for disabled people wasn't big enough.
