a bunch of orange containers/etc that I have beg to differ.
for removing fats and for actual washing there is a main cycle that runs hot

TC made specific claims about the benefits of a hot pre-wash. Instead of countering those, the blog's author decided to ignore them and build his own strawman to attack.
The author should have refuted the specific claims, or acknowledged them before moving to the drawbacks.
in general, it's hilarious. there are literally dozens R&D departments that design dishwashers across dozens of companies. And all of them are wrong because somebody run tests on (checking notes) 30 years old dishwasher.
i trashed dishwasher similar to the one that tests are run on 4 years ago. it was washing everything just fine with exception of few days when check valve broke. after i replaced it, it came back to washing perfectly with cascade platinum pods
This is why you pre-run the hot water in the tap (assuming the dishwasher is attached to the hot water tap/pipe), so the dishwasher has hot water for the pre-wash already. Works for us for a better overall cleaning.
if dishwasher manufacturer thought that prewash needs hot water, it would have heated it to appropriate temperature like it does when it needs to.
It's because, as outlined in the linked article, hot water makes the problem of staining plastic worse. So they try to mechanically remove it before the main wash. Note that in the original video, the main wash heat temperature wasn't impacted by preheating the prewash.
They literally do! https://i.imgur.com/gCDuZZM.png
Rather than jumping into this whole thing in the middle, I'll ask you to begin from the beginning, catch up on what you missed on (the two earlier Technology Connections that were made before the submission article), so we can at least have the same base-level understanding of the situation first, then you can come back and we can argue the entire day.
This screenshot is seems to be from manual of Frigidaire FDB520RHB or something similar that was discontinued 12 years ago or so.
Some of the programs of this dishwasher will heat water as needed, and in addition there is a button "hot wash".
showing manual of 20 years old machine today as proof for how machine should be operated it's just like arguing with todays doctor using 300 years old medical books.
things changed.
