So the dishwasher will just continue to drain. You can set it to wash it will fill but will not was because the pump continues to evacuate the water causing it not to wash. It will run through the complete cycle, display shuts down but still pumps...have to open the door for it to stop.

I've ran hot water through it, tried to readjust the drain hose.

Pump, relay or main board? It is only about 3 years old, hate to throw the wrong parts at it and could have bought a new one.

Any idea's?

Thanks Dave

Thank you very much. I'll go that route. I do appreciate it.

You are welcome

And thanks for getting back to us. Now when others search for a similar problem they will see what actually worked instead of just suggestions about what could be the cause.
