Some dishwashers have built-in "hard food disposers" (like a Piranha blade) to pulverize food before it drains, while others use manual filtration systems that require you to occasionally clean out a catch trap. Neither type, however, is a substitute for the heavy-duty garbage disposal under your sink.
Plumbers hate garbage disposals because they give homeowners a false sense of security. Disposals encourage people to wash food waste, grease, and starches down the drain. This creates thick, slimy sludge blockages in the pipes that are difficult to clear with a standard plumbing snake.

Using dish soap in a dishwasher creates a thick, sudsy foam in the appliance that can overflow through the dishwasher door.
