About a week ago, I had a panel change at the house. That night, the Tesla wouldn't charge.
I called the electrician, and he showed up the next morning and opened the outlet to see if anything looked wrong. He then, closed it up and viola! The car began charging again. He said that he had really not done anything, but there you go...
Fast forward 4 days and on Saturday, the car charged in the morning, came back after errands and refused to charge again.
UMC Shows top green light and flashes red small LED 4 times, sometimes 3... Called Tesla service and they say that it's electrical... Car charged at a charge point charger, and will *sometimes* charge at home..
Today, it charged over night and was at full charge in the morning, but now won't charge at all... This time ONLY a red light on the UMC, and the Red Ring on the charging port. Won't charge at all.
Will charge on 110 though.
Now my electrician says that the outlet is setup correctly (there wasn't anything done to the outlet, which has been in service since 2014). The panel change happened before the sub-panel which has my 50 AMP GFI circuit that feeds an inside and outside NEMA14-50.
According to the electrician, the outlet couldn't have a ground fault as indicated by the warning LEDs because the GFI wouldn't allow the circuit to be closed.
Does this sound correct? Could it just be the 220 Plug adapter that is bad?
Thanks for your advice, I am headed to the local Service Center to have them test out the UMC and probably swap it for a new one.
