Dishwasher doesn't fill/How to check... (by 2 users)

Set the washer to run its normal cycle and went out for dinner. Came home hours later and washer is still running. Can't get reset/self test diagnostics through manual or other source. Found a clog in the breather valve and have cleared it. When attempting to snake the drain line, the plastic hose detatched and the soapy water that had remained leaked out under the machine. Now, machine sounds like it's running constantly, trying to drain. I've filled the bottom with water and when I press the on/off switch, the water is drained away, but the machine doesn't go to the next cycle. Is there a "reset" button or switch for this model?
