If the dish has bits of e.g. vegetable matter beyond a certain size which would ultimately need to be manually cleaned out the dish washer's filter after some time, then I will at least scrape off the contents of the plate first, and occasionally I may do a 2 second rinse of a plate under my tap.
You mean you don't eat all your food? Disgraceful! Children starving in Africa etc.
This is basically what I do. Have never needed to clean out a dishwasher filter and it’s never had a foul smell from food bits. I have a garbage disposal to use for that, or prefer to toss larger waste pieces in the trash directly. Also plates are the low hanging fruit where a simple scrape off is usually enough. Pots, pans, and baking dishes often have more burnt on crustyness that I scrub at for a few seconds and that I just assume would be difficult for the dishwasher to handle or would stick in the filter.
Maybe this is why the quick wash is always enough for my dishes.
