It depends. What you describe is common with American dishwashers. European dishwashers typically don't grind anything up, they just collect it in a sieve.
If you buy a dishwasher with that feature. It's not standard. I know because my parents went cheap on their last dishwasher purchase because "they're all the same." About two years later I got to help troubleshoot why their dishwasher wouldn't get anything clean... the bottom of it was basically a solid layer of rotten food particles.
