When a residential electric vehicle (EV) charging station displays a solid or blinking red indicator light, it is signaling an internal fault code, safety protection trip, or hardware error that prevents power delivery. Common triggers include a ground fault interruption caused by moisture or damage in the charging cable, an over-voltage or under-voltage condition from your home electrical grid, a thermal overload protection shutdown due to excessive heat in the charging handle, or a failed internal relay. You can troubleshoot EV charger errors safely by standing on a dry floor and avoiding wet hands. You can verify that your corrective action is successful when power-cycling the unit via your home circuit breaker or clearing error codes allows the LED indicator light to return to a steady green or blue ready state.
