What really happens inside a dishwasher?

 I have to admit to being a bit fascinated to find out what this was really like.

YouTube user Bito posts:

Always wanted to see what happens in my dishwasher after I close the door. Many of the other videos I saw had terrible lighting or bad angles.

Using a Hero 3. I had two light sources reflecting at different angles.

This was my third attempt. The biggest problem I had to overcome was the heat and battery time.

Ok, after a bit it’s repetitive, but still to know how (or not) how your dishwasher actually gets anything clean was interesting.

I was born curious.
