Have had HPWC for 8 months , all have been well. All of the sudden, car will not charge via HPWC. I removed HPWC and connected via 6-50, still the same. I see 248v but amps, just does not ramp up. I connect to 120v, and the car charges OK. Took car to Tesla service center, they plugged it into their HPWC and it charged fine. Johnathan in Rockville MD, was extremely accommodating. Thanks. Came back home, redid the connections, changed the breaker, no can do. Nothing works. The installer gave me some insanely thick 100A cable, you have to skip a few stands to be able to push into the connectors, both on the HPWC and the 6-50 socket. My breaker is 100A, my panel is 200 Square-D. I moved the breaker one slots down, no dice. Any ideas?
