My whirlpool dw did the same thing. There is a check valve in the elbow of the drain tube that attaches to the dw. Mine was leaking and allowing water to run back from the drain. Sounds like you are getting water from the disposer. I suggest replacing the drain tube, not with a generic one from a home improvement store, but an official one from here that has that valve in it.

Hello,

There is a check valve screwed into the pump (#15 at the diagram). Remove the toe panel. Disconnect the drain hose from the check valve (be prepared to catch water remaining inside the pump and the hose).

Unscrew the check valve and check for a clog inside. Replace the check valve if it's broken.
