Mower shows E23 and stops; message may indicate security or PIN code error.

Safety: Security faults do not affect mechanical safety, but keep blades stopped while troubleshooting.

• Verify PIN: Carefully re‑enter the correct PIN. Check the user manual or Yarbo app for the default or previously set code.
• Use Yarbo app: If the mower is linked to your Yarbo account, use the app to unlock or reset the PIN following the in‑app instructions.
• Check buttons: Test each keypad button for proper response. If some buttons do not register, the keypad may be faulty.
• Contact support: For locked units where the PIN cannot be recovered, contact Yarbo support with proof of purchase for a secure reset procedure.
