A Tesla wall charger blinking red 6 times indicates that there is an overvoltage or poor grid quality detected. This means that the voltage coming into the charger is outside of the safe range, or that there is some other problem with the electrical grid.
To fix this problem, you should first check the voltage coming into the charger with a multimeter. If the voltage is outside of the safe range, you will need to contact an electrician to correct the problem. If the voltage is within the safe range, then you may need to reset the charger. To do this, turn off the circuit breaker for the charger, wait 5 seconds, and then turn it back on.
If the charger is still blinking red after you have reset it, then you may need to contact Tesla customer support for further assistance.
Here are some additional tips to prevent your Tesla wall charger from blinking red:
- Make sure that the charger is properly installed and grounded.
- Avoid using extension cords.
- Do not overload the circuit that the charger is connected to.
- If you are experiencing frequent overvoltage or poor grid quality, you may need to install a surge protector.
I hope this helps!
