I still figured that avoiding all those water changes at the start of the cycle would've been a good idea. By the time the machine has finished the 3rd Pre-Rinse, the dishes must be clean by that stage.
My other "idea" was the usage of Rinse-Aid wold alleviate the problem mostly anyways, as it did when we used our Dishwasher without the filter (when it came apart). Of course, I used Heavy to get rid of the chunky soils, and for the 3 post-wash rinses, but I noticed that until the Rinse-Aid dispensed, everything was coated with rubbish (specs of food, like coffee grounds). After that, clean as a Concorde!
