Robot vacuum shows E14 and cannot connect to Wi‑Fi or the Kyvol app.

Safety: No electrical disassembly needed for basic checks.

• 1. Check network:
  • Ensure your router is broadcasting a 2.4 GHz network (most Kyvol robots do not support 5 GHz only).
  • Confirm the password is correct and there is internet access.
• 2. Move closer to router:
  • Place the dock and robot within 3–5 m (10–15 ft) of the router during setup.
• 3. Reset Wi‑Fi on robot:
  • Follow the Kyvol manual to enter Wi‑Fi pairing mode (usually by holding a specific button until a tone or voice prompt).
• 4. Update app/firmware:
  • Update the Kyvol app to the latest version.
  • Once connected, check for robot firmware updates.
• 5. Hardware fault:
  • If the robot never enters pairing mode or always shows E14, the Wi‑Fi module on the main board may be defective and require board replacement.
