Charger displays E15 and refuses to start; often after a failed RFID or app authorization attempt (for models with access control).

Safety: This is a logic-level fault; standard electrical precautions still apply when opening the unit.

• 1. Try manual override (if available):
  • Use the AMPROAD app or local menu to temporarily disable access control and test charging.
• 2. Reset access settings:
  • Clear and re-add authorized users/cards via the app or web portal.
• 3. Inspect RFID reader:
  • Check the reader window for cracks or water ingress.
  • With power OFF, reseat the reader’s connector on the control board.
• 4. Firmware / configuration sync:
  • Ensure the charger has synchronized with the AMPROAD cloud (if applicable) and that firmware is up to date.
• 5. Replace reader module: If E15 persists and the reader is unresponsive, replace the AMPROAD RFID reader module.
