Dishwasher detergent doesn't make suds. Dish soap does. Are you sure you're using the correct stuff? Or prewashing the dishes for some reason and not getting all the soap off?

Anecdote: My spouse and I visited some friends for supper at their place. After the meal, was when they decided to try out the dishwasher in their apartment for the first time.

With dish liquid.

It's almost like the movies where the wash machine fills the house with suds, and the occupants go floating out the front door.
