Tesla Wall Charger Flashing Red

A Tesla wall charger flashing red indicates that there is a problem with the charger. The specific problem will depend on the number of times the charger flashes red.

• One red flash: This indicates a ground fault circuit interruption (GFCI) due to an unsafe current path. This can happen if there is a break in the connection between the charger and the batteries.
• Two red flashes: This indicates a ground assurance fault or a high ground resistance has been detected. This can happen if the charger is not properly grounded.
• Three red flashes: This indicates a high temperature detected by the charger. This can happen if the charger is overheating.
• Four red flashes: This indicates a communication error between the charger and the Tesla vehicle. This can happen if the charger is not properly connected to the vehicle or if the vehicle is not turned on.
• Five red flashes: This indicates a power-sharing communication issue. This can happen if the charger is connected to a circuit that is also being used by other devices.
• Six red flashes: This indicates an overvoltage or poor grid quality detected. This can happen if the voltage coming into the charger is outside of the safe range.

If your Tesla wall charger is flashing red, you should first check the charger for any obvious signs of damage. If you do not see any damage, you should contact Tesla customer support for help.

Here are some additional tips to prevent your Tesla wall charger from flashing 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.
• Keep the charger clean and free of debris.
