Display shows E12; charger cannot connect to backend or app services, but local charging may still work.

Note: This typically affects smart features, not basic charging.

• Check internet connection: Verify that your home router is online and that other devices have internet access.
• Verify network cables: For Ethernet‑connected Amperfied units, ensure the LAN cable is firmly seated at both the charger and router/switch.
• Wi‑Fi signal strength: If using Wi‑Fi, check that the charger is within range of the router. Consider relocating the router or adding a Wi‑Fi extender.
• Reconfigure network settings: Use the Amperfied app or web interface to re‑enter Wi‑Fi credentials or IP settings as per the installation manual.
• If E12 persists: The internal communication module may be defective and require replacement by a technician.
