E17 displayed; charger indicates "Card Error" or "Auth Fault"; cannot start session.

Note: This affects access control, not the power electronics directly.

• Try alternate authentication: If supported, use the GoCable app or PIN code instead of RFID to start a session.
• Clean RFID area: Wipe the RFID reader surface with a soft, dry cloth to remove dirt or stickers that may interfere.
• Re‑register cards: Use the admin menu or app to delete and re‑add RFID cards.
• Inspect RFID module: With power OFF, open the front panel and ensure the RFID reader board is securely connected to the main control board via its ribbon or cable.
• Firmware/database reset: Perform a user database reset if available, then re‑enroll users.
• Persistent E17: Replace the RFID reader module or, if that fails, the front user interface board.
