Yes we have removed the drain mesh trap and screen. It is clean with no
stuff in it. The water that I said is always in it is by the pump when
you
remove the screen. It is in that bottom well that the screen covers. You
can not see it puddled in the bottom of the dishwasher, just when you
remove
the screen and look in the round screen hole. We think that is where the
stink is coming from.
Thanks again.

Should be water there...but if your drain hose is not installed so it loops
above the highest possible water level in sink before it comes back down
into the disposer/p-trap connector, you could be getting too much or even
drain water from the sink or disposer back into the dishwasher. Some
locales require a vacuum break installed between the d/w and drain
connection to prevent this. Also, if you only run it once a week or so,
the water there will sour just as it would if you left a sink full of dirty
dishwater for a week. Dishwashers and washing machines need to be run often
to prevent the residual water from stinking.
I've never heard of vinegar being a cure for your problem but it is great
for keeping the inside stainless spotfree and your glasses spotfree. Even
helps if you also have a water softener.
