Wall Connector 1 Red Blink Symptom Verification

A 1 red blink pattern on the Tesla Wall Connector signifies a ground fault. To verify this condition, observe the LED light bar on the front of the unit; the light will blink red once, pause for one second, and then repeat. Inspect the charging handle, the charging cable, and the vehicle's charge port for visible signs of damage, debris, or moisture ingress, as these are the primary external indicators associated with this specific fault code.
