Display shows ERR HOP or similar hopper-related error; grill reports a pellet supply issue even when the hopper contains pellets.

Safety first: Turn OFF and unplug the grill before accessing internal wiring or sensors.

Steps to troubleshoot hopper sensor errors:

• 1. Verify pellet level: Ensure the hopper is at least half full with dry, clean hardwood pellets. Avoid using pellets with excessive dust.
• 2. Clean the hopper: Scoop pellets into a container, vacuum out sawdust and debris from the bottom and around any visible sensor components.
• 3. Locate the pellet level sensor: On Twin Eagles models equipped with a level sensor, it is typically mounted on the side or bottom of the hopper, sometimes as an optical or mechanical switch.
• 4. Inspect and clean the sensor: Wipe the sensor surface with a dry cloth. Ensure no foreign objects are blocking it.
• 5. Check wiring: Follow the sensor wires to the control board and confirm the connector is secure and undamaged.
• 6. Replace the sensor if needed: With power disconnected, remove mounting screws, disconnect the harness, and install a new Twin Eagles-compatible hopper level sensor.

If the error persists with a new sensor and clean hopper, the control board may be misreading the sensor and should be checked by a service technician.
