Chet,
In answer to your questions;
1) Very easily, this is a basic requisite of any dishwasher.
2) That dish was in a fully stacked “Bobload”, loaded alongside saucepans, plates, glassware, teapot, Pyrex jug etc. and a fully loaded cutlery tray. No redeposits on anything. Rinse water is always clear on the one time I’ve bothered to check. Each water fill is 2-3 litres, usually with 4 or 5 water changes depending on the load. Should I want more water, a forced prewash and an extra rinse, I can choose to do so with an option but I never really have the need to. Everyday items without any baked on soiling come clean from the quick cycle (which can be either 58mins or 1:23) with just 3 water changes and 8-9l of water.
3) No particles remain at all on the load at the end of the cycle. I have even dumped the coffee grounds from my bean-to-cup coffee machine, and asides from one or two tiny grounds there was no evidence of coffee. I would count that as a success.
All with minimal amounts of water, but enough to do the jobs. Pretty much any decent modern European dishwasher can achieve this.
It sounds like we agree on what needs to be scraped off, so I don’t see your earlier point of any excessive pre-prep that supposedly has to be done before loading a filter based dishwasher. The detergents dissolve most food particles which are flushed down the drain when the machine pumps out.
I can understand your scepticism if you’ve never had any direct experience, and you’re right to question anything you personally can’t understand and find difficult to believe. I cant comment on the US dishwashers as I have never used one but all I can do is testify to how well our filter based dishwashers work here, with as little energy/water as possible. And I’m sure you will agree that if something can be done to a high standard in the least wasteful way possible, that is only a positive thing for the world.
On a different subject, for the sake of your health I would look at moving away from all that awful processed food in your diet, it’s not good for you.
