Robot vacuum shows E12 and cannot connect to Wi‑Fi or the AEG app.

Safety: Keep the robot on the dock while troubleshooting.

• Check network: Ensure your router is broadcasting a 2.4 GHz network and that the password is correct.
• Move closer: Place the dock and robot within a few meters of the router during setup.
• Reset Wi‑Fi: Use the Wi‑Fi reset procedure (usually holding a specific button until a tone or indicator flashes) and re-add the robot in the AEG app.
• Reboot router: Restart your router and try again.
• If E12 persists: The Wi‑Fi module on the robot’s main PCB may be defective and require board replacement.
