The HPWC was purchased last April at the time of the car and have had zero problems since. I just noticed when I plugged it in a few minutes ago, I didn't hear the contacts close and noticed on the screen it says, "No Wall Power - Check power source. Charging stopped". I pressed the reset button on the HPWC, but it didn't seem to do anything. I turned off the breaker and turned it back on. No difference. I rebooted the main screen in the car, no dice. After about 30 seconds the charge port changes to red. I've been on hold with Tesla for about 15 minutes and am waiting for a call back. Any ideas in the mean time?
