Noticed my car reported not getting power after plugging the charger in. Reset wall connector, at first it flashed orange 4 times. Which I believe is ground problem. Nothing appears to be wrong with the ground connection. After a while the charger is now showing green (we didn't change anything!). The car is still complaining it is not getting power however. The button on the charge plug doesn't work either. Resetting the wall connector - by pushing the reset button and cycling the breaker hasn't changed anything. It is still showing green. Any ideas?
