Charger displays E10; Wi‑Fi or Ethernet connection is lost and remote control may not work, but local charging may still be possible.

Safety first: Network faults are low risk electrically, but always isolate power before removing covers.

• 1. Check external network: Verify that the router or switch is powered and that other devices on the same network have internet access.
• 2. Inspect Ethernet/Wi‑Fi hardware: For Ethernet, check the RJ45 plug is fully inserted and the cable is undamaged. For Wi‑Fi, ensure the antenna is firmly connected and not broken.
• 3. Reboot devices: Power cycle the Vestel charger and the router/switch. Wait a few minutes and check if E10 clears.
• 4. Verify network settings: Access the charger’s local configuration interface (via service port or local Wi‑Fi AP) and confirm IP settings (DHCP/static), gateway, and DNS are correct.
• 5. Inspect internal comms module: With power off, locate the communication module (often a plug-in PCB or daughterboard). Reseat it in its socket and check the ribbon or harness to the main control board.
• 6. Replace communication module: If physical connections and network are OK but E10 persists, replace the Vestel communication module with an identical part.
