But the concept is fine. Lots of manufacturer's used to include video in their commercials of an appliance with a clear wall so you could see it in operation, dishwashers included. I find it informative. From this video I would be very conscious of how flimsy that center spray nozzle is in a dishwasher I was considering purchasing.

I like the commercials for motor oil that show how an engine works and where possible friction could occur. I may never need any of that superficial level knowledge but it gives me a basic starting point when considering maintenance.

should never run a dishwasher unless it's full. Money down the drain so to speak.

Freud would have a field day.

Does the light stay on after the door is closed?

That would have been worth watching a few times.

This is a much cooler video to check out. Five people playing a song on one guitar.
