Viking dishwasher that does not stop draining

If the cycle does not stop draining that is usually because of a faulty water level sensor. The floater that controls the water level in your appliance.
The faulty sensor cause the machine to think that there is still water inside, even when water has drained completely. Check if sensor is stuck or if switch is faulty.
Some machine may use a membrane switch instead of a floater.

I have the same thing, unit pump keeps running, when I pulled it from under the cabinet, if you tilt it back a little it stops, as soon as you lower it back down the pump starts to run again. Getting code as too much water in the tank even though it is empty. PLEASE HELP!!!!!
