Safety first: Network troubleshooting does not involve high voltage, but do not open the charger unless qualified.

Check Wi‑Fi signal: Use a smartphone at the charger location to verify signal strength. If weak, move the router or add a Wi‑Fi extender.
Re‑enter credentials: In the VW wallbox setup app, forget the current network and reconfigure Wi‑Fi with the correct SSID and password.
Test with mobile hotspot: Temporarily connect the VW wallbox to a phone hotspot (if supported) to rule out router issues.
Reboot router and charger: Power cycle both devices and test again.

If E013 continues with known‑good Wi‑Fi, the internal communication board or Wi‑Fi module may be defective and require replacement.

VW wallbox shows E013; charger cannot connect to backend services; remote control via app fails.
