Water Backing Up in Dishwasher and Disposal

If the machine is still working, sort of, but runs a cycle without completely pumping out, try running vinegar through it or the Jet Dry dishwasher cleaner. If the machine no longer pumps out, you could look to see if there are clogs in the pump out filter (this is in different places in different machines, you have to get in there and look around), and see if you can manually unclog it. If not, it is time to call a repair person.
