Replace the water temperature sensor and still had the error code. While I had the back of the machine open I ran the washer. I traced the black wires from the temperature sensor and wiggled them as the washer was running. At one zip tie every time i moved the wires the washer would stop running and the error code would flash. Sure enough, like many others posted, the vibration from the machine had split the wire. I spiced the wire back together and have not had a problem since.
