About every other week my car stops charging after a few minutes and reports error code CP_a057. I charge about every 2 or 3 days. I noticed today before I plugged in the wall charger was flashing red on the "T" at the top. It always starts working again when I unplug it from the wall and plug it back in again. I have checked the connections in the outlet everything is fine. It is a new panel and was installed by a really good licensed electrician. I leave the wall part plugged in inside my garage - always. Could that cause a problem?
It always fixes the problem for a while when I unplug and pug back into the wall.
