Charger shows E016 and cannot connect to Wi‑Fi or Ethernet; smart features unavailable.

Impact: Charging may still work in basic mode, but remote control and monitoring are affected.

• Check basic charging: Verify that the charger can still start and stop charging manually. If so, the issue is limited to networking.
• Verify network settings: Using the local interface, confirm SSID, password, and IP settings. Reset to DHCP if static IP is misconfigured.
• Test Ethernet: If using Ethernet, try a known-good patch cable and a different router/switch port.
• Module reset: Some ABB chargers allow resetting the communication module separately via the menu; perform this reset.
• Inspect module (technician): Open the charger and ensure the Wi‑Fi/Ethernet module is firmly seated and its antenna (if external) is connected.
• Replace communication module: If E016 persists, replace the ABB communication module or user interface board that hosts the network hardware.
