There is no precision to the temperature or time control of a dishwasher, and there’s no dry cycle on a sous vide.

Yes it goes without saying it's lacking the precise controls, but it's still the same mechanism of cooking in the end.
A sous vide bath won't replicate any of those steps (except maybe the steaming if you run the bath at practically boiling). Sous vide will cook good salmon but it's not a drop in replacement.
Mine is just a single constant temperature the whole time.
There's certainly no high heat much less sterilization, just bringing the water up to temperature and keeping it there, through pre-wash, wash, and rinse cycles. (Only commercial restaurant dishwashers get up to sterilization temperatures.)
And if the salmon is wrapped airtight, there's no conceptual difference between broiling/steaming/baking. It's all just sous vide, which is none of those. Because it's sealed.
If you wanted to be super pedantic about it, you'd say that none of this is anything like "sous vide" because "sous vide" implies "under a vacuum".
At any rate: dishwasher salmon and sous vide salmon are, literally, the same dish.
Of course the workers would surreptitiously snip a bit of choice meat from the carcass, and drop it in the water to cook. They were not supposed to, but it was difficult to police.
It is possible to sous vide without a vacuum bag in a steam oven, or in certain ovens with temperature probes.
I've cooked 'sous vide' under a running hot tap in a backpacker, which worked great. The water temp happened to be close to perfect (I have a method of measuring temperatures > 40c based on how long I can hold my hand under the running water before pulling out from the pain - surprisingly accurate).
Its about temperature control and efficient thermal transfer; vacuum sealing and using a circulating, temperature controlled water bath are mechanisms of achieving that.
En Papillote and via Dutch Oven are other similar techniques utilizing the same concept. Maybe I'm overgeneralizing?
