It's possible your water solenoid is bad. I would take the top lid off and check the solenoid terminals for continuity. If that checks, then I would test the wiring connections at the water solenoid for voltage (assuming your are comfortable testing the high voltage). I believe there s/be 240v. See if you are getting power to the solenoid as soon as you start the cycle, and if not, consider replacing that solenoid.
