Control panel displays ERR9 and Wi-Fi or app connectivity fails (on Wi-Fi enabled models)

Safety first: Network troubleshooting does not require opening the grill, but always keep the lid closed and avoid hot surfaces.

• Check signal strength: Ensure your home router is within range of the grill. If the signal is weak, move the router closer or use a Wi-Fi extender.
• Power cycle: Turn off the grill, unplug it for 60 seconds, then plug it back in and restart. Also reboot your router.
• Re-pair the grill: Follow the Char‑Griller app instructions to forget the grill and set it up again, ensuring you use the correct 2.4 GHz network if required.
• Firmware update: If available, update the grill firmware through the app once connectivity is briefly established.
• Hardware check: If ERR9 persists and other functions work normally, the Wi‑Fi module or control board may need replacement. Contact Char‑Griller support or a technician for a replacement control board.
