Possible Causes

Corrupted firmware on Nissan EVSE control board, Failed internal relay or sensor detected at startup, Power supply fault on low-voltage section, Damaged control board from surge or moisture

How to Fix / Troubleshooting

Safety first: Turn OFF the breaker before opening the unit. Do not attempt board-level repairs without proper training.

  • Full power reset: Turn the breaker OFF for at least 5 minutes to allow internal capacitors to discharge. Turn back ON and observe if E10 clears.
  • Check for obvious damage: Open the EVSE and inspect the control board for burn marks, bulging capacitors, or corrosion. If present, the board must be replaced.
  • Verify supply stability: Have an electrician confirm that the input voltage is stable and within spec; unstable power can cause self-test failures.
  • Firmware/service check: Some Nissan EVSE models may support firmware updates via service tools. Contact Nissan Energy support or an authorized installer to check for known firmware issues.

Persistent E10 indicates an internal electronics fault. Replacement of the control board or entire EVSE is typically required.
