I find that recent models of dishwashers don’t work nearly as well as older models. They don’t heat up enough to dry water off of plastic, and the enzyme based detergents don’t seem to clean as well as the old phosphate detergents.

Also, the dishwasher in our current apartment (a cheap Whirlpool) often leaves a wet dog smell on the glasses, and we can’t figure out where it comes from or how to get rid of it. Apparently, this is a rather common problem, with hundreds of posts scattered across the internet where people with the same problem unsuccessfully try dozens of home remedies that fail to fix the issue. I never remember wet dog smell from the older units so I can only assume this results from some sort of energy saving feature that backfired.
