120 volt charger - green & red light blinking

The indicators are described on pages 109–110 of the Owner’s Manual (PDF); the chart on page 110 explains the meaning of each combination of lights.

I’m not sure about the colors (which might differ from one cable to another), but if the POWER and ⚠ indicators︎ are both flashing, this means, “There is a malfunction in the plug temperature detection part.” As you may know, there is a temperature sensor in the plug, to detect overheating and reduce the charging current.

The Repair Manual says for this condition, “Check for an open in the electric vehicle charger cable assembly.” You may have a damaged or defective cable; ask a dealer to inspect it.

 

Are you using an extension cord?

Are you charging at 8 amps or 12 amps? There is a choice. Does it make a difference?

 

You can disable 12 amp in the settings. A lower charge setting might not throw the warnings. Page 123 in the USA manual explains how to limit the charging to a lower amperage (of two). The most common charging problem is tripping the breaker due to a higher than expected load. But this might help to identify a potential problem or situation with your error lights.

Your charging time will increase at 8 amp of course, but the lower power might allow it to work? You should probably find out if your outlet can handle the 12 amp setting in the car, which I think is the default. It won't be the car if that's it, but most likely your wiring (or if using an extension cord?) You'll need a 120v 20 amp dedicated (mostly) house circuit to charge at the higher 12 amp setting.

With L2 240v charging (not your use case), the circuit should be able to handle 40 amps, even though the car can only receive the highest charge at 16 amps at 240v.

 

Happy you have it sorted. Only 27? That's a quarter of what mine is! Guess I'm glad I paid the electrician (big bucks) for new power out to our two EV circuits we plug into. I don't even want to think how bad the rest of our house's wiring is.

You might have had a slight grounding problem with that outlet. My electrician insisted that the 120 had a GFI as part of the install. The 240v line didn't require it, since the EVSE has that built in.

 

Yes. Tried unplugging but problem remains. Also taking 12 hrs to charge instead of 5.

 

try another outlet, another circuit and a public charger.if all fail, try it at the dealer.
