Possible Causes
Faulty DC leakage sensor in Nissan EVSE, Internal insulation breakdown in EVSE filter capacitors, Vehicle-side DC leakage exceeding EVSE limits, Moisture contamination on control board
How to Fix / Troubleshooting
Safety first: DC leakage faults relate to shock protection. Do not bypass any protective devices.
- Check environment: Ensure the EVSE is not installed in a location with persistent condensation or direct water spray. Dry the area and unit if damp.
- Inspect for contamination: With power OFF, open the EVSE and look for water marks, corrosion, or insect nests on the control board and around the leakage sensor. Clean dry debris with a soft brush; do not use water.
- Try another vehicle: If available, test charging a different EV. If E08 only occurs with one car, the vehicle may have a DC leakage issue requiring dealer service.
- Reset and monitor: After drying and cleaning, restore power and attempt a short charge. If E08 returns immediately, the DC leakage sensor or control board is likely defective.
Because DC leakage protection is critical, replacement of the sensor/control board should be done by a qualified EVSE technician.
