Display shows ERR9 and Wi‑Fi or app control does not function

Safety first: Only work inside the control panel with the grill unplugged. Network troubleshooting can be done with power on but without opening the grill.

• Verify local Wi‑Fi: Check that your home router is working and that the grill is within range. Avoid placing the grill behind metal structures that can block signal.
• Reset network settings: Follow the Char‑Broil manual to reset the grill’s Wi‑Fi settings (often involves holding a specific button combination). Then reattempt pairing in the Char‑Broil app.
• Power cycle: Unplug the grill for 5 minutes, then plug it back in and retry the connection process.
• Inspect control board (if still failing): With the grill unplugged, remove the control panel and inspect the Wi‑Fi module or antenna connection on the control board. Ensure the antenna wire is firmly attached and not damaged.
• Firmware update or board replacement: If the app or manufacturer support indicates a firmware issue, perform an update if available. If ERR9 persists and Wi‑Fi remains nonfunctional, the control board may need replacement.
