It sound that the problem is cause the water level switch (stuck in the "full" water position). The switch level is usually a diaphragm device with a small clear tube attached between the switch and the bottom of the washer's outer tub. I am not familiar with this specific machine, but if you will open the rear panel you will find it easily. Clear first any obstruction in the tube,In case it doesn't help, disconnect the wires from the unit (you should disconnect first machine's power cable !!!!!) and measure with a multi-meter on its tugs for continuity and disconnection while you are inhale and blow to its tube. In case it doesn't react, you should replace it. Good luck !
