I have been using a Tesla wall connector for 2+ years with no issues. Installed through Tesla's recommended licensed electrician. All of a sudden my wall connector stopped working and I called an electrician, he came out within 3 hours and inspected everything. I was with him all the time and everything looked 100%. All cable, switch, wirebox, breaker, all voltage reading looks good. I called Tesla and they are saying they are seeing grounds error on their side. Which I haven't seen on my side( no msg, no red light, etc) till now. Basically, they are saying it's an error on my side and that's why it's died. It's still under warranty. I don't what to do. Please advise. Anyone experienced anything like that?
