we just installed new Kitchenaid dishwasher on our own. We connected it to a new plastic pipe that came with the unit and connected that to the black tubing which goes to an air gap and then to the garbage disposal. After installation we ran our first load. All seemed well until the next morning when I went to unload dished I can see water standing in the bottom (soapy). I shut the unit and tried to drain several times. I can hear the pump turning on but no water is entering the tubing. We did not previously have drainage issues so I don't believe it is any blockages (but I am planning on checking). I am thinking it is the pump since no water is even entering the lines.
