In a previous post Jennifer says...
Consumer Reports tests dishwashers regularly, using a mess of oatmeal
and spinach that's been allowed to harden on dishes overnight. They
reported last year that most current-model dishwashers had no problem
cleaning those dishes completely, with no soaking or rinsing.


The problem with not rinsing is not the stuff that gets stuck on, but
the fish bones or broken glass that make it past the screen and grinder.
These get stuck in the discharge pump and will trap anything else headed
for the disposal.

I have a fairly new Frigidaire that I have had to take apart more than
once because fish bones or a piece of broken glass got past the screen.
