Filters
You might find that the filters generally keep themselves clean during the course of operation. Although it may still be prudent to keep an eye on the filters for now to see whether they largely keep themselves clean or not. You certainly will find large chunks of food that don't break down and move through the filter - otherwise I shouldn't think much of anything will remain.
The impellers on these pumps can do more damage than one thinks... If I put lots of rice into our machine, even without the grinder I can hear the rice being ground my a little rubber impeller!
From what I have observed on other machines (A Miele G976 SCU Plus and an "Emilia" dishwasher) with manual-clean filters, the water path during drainage seems to be designed so that the filter is backwashed clean, and even vice-versa. This, and the wash-arm often has jet/s underneath to help spray the filter clean during the wash phase - although the effectiveness of that jet still leaves something to be desired on some models, especially when frequently dealing with heavily soiled loads (My DD)...
In any case though, the self-cleaning method of those filters will always leave something to be desired, and as others have said, when they remain dirty through all the washes and rinses, your dishes aren't actually clean. They are "Clean," although with caustic detergents and high temperatures, I would not be overly concerned about that.
