Wall charger stops charging after a few hours.

[Mohsin Iqbal]

Have Tesla Model S since Jan 2020. Had Tesla home wall charger installed at that time. Everything has been fine so far, About one week ago, wall charger starting acting up. When plugged into the car, charges for about 2-3 hours, then stops, one red light on the charger blinking three times. Removing charger from the car and re plugging starts charging again but then would stop again after a bit, same one red light blinking three times.
Have turned off circuit breaker and back on. Wall charger connected to wifi and updated, problems continues.
Any other trouble shooting steps to do? Have contacted Tesla but their next appointment if about two weeks away.

Thanks all for help.

3 red blinks = overheat condition.
Get it checked out.

I got it checked by an electrician, there was one wire that was a bit loose, tightened, everything else including voltage etc looked good. Tried charging again, it was able to charge all the way, however while charging, with green lights going downwards as always, also getting one red light at top blinking constantly. Dont think it is supposed to do that. Problem with charger itslef?
Thanks

Sounds like the one you describe is also for an overheat condition.

Three red blinks, with green streaming	High temperature detected; charging is limited	Charging amperage has been reduced due to high temperatures. Connect Wall Connector to Wi-Fi so that firmware can update to most recent version.

Just a follow up. Seems like problem with internal component of wall charger, over heating. They are sending me a new one. Thanks all for help.
