at some point the dishwasher stops and quits working and leaves dishes dirty, and water in bottom of it ande the heavy and pots and pans lights are blinking even though i did not run a heavy or pot and pan cycle. And when we took it apart to check for a clogged hose or drain the black tar stuff on out side of washer was all melted and had ran down on the motors. we removed all the melted stuff and ran it again only for the same thing to happen.
