Charger shows E13 and stops charging; app may indicate ‘DC leakage detected’ or ‘DC fault’.

Safety: DC leakage can interfere with RCD operation. Do not bypass this protection.

• Step 1 – Retry with same vehicle: Power cycle the charger and attempt another charge. If E13 recurs immediately with the same vehicle, note the vehicle model.
• Step 2 – Test with another EV: If possible, test with a different vehicle. If E13 only occurs with one car, the issue may be vehicle-side and should be checked by the car manufacturer.
• Step 3 – Inspect sensor: With power OFF and cover removed, locate the DC residual current sensor (often combined with AC RCD). Check for moisture, dust buildup, or loose wiring.
• Step 4 – Dry and clean: Gently clean around the sensor with a dry cloth and allow any moisture to evaporate.
• Resolution: If E13 occurs with multiple vehicles and wiring is intact, replace the DC residual current sensor module or the main control board as specified by Enel X service documentation.
