Wolf Cooktop Error Code FG

The FG error code on Wolf Black Hood ventilation systems is a Mesh Filter alarm, a scheduled maintenance reminder indicating that the mesh grease filter requires cleaning or inspection. This is not a fault code tied to a hardware failure or electrical malfunction. Instead, it is a usage-based alert built into the hood's control system to help maintain optimal airflow and grease capture performance. The alarm triggers after a set number of operating hours have accumulated, signaling that grease buildup on the mesh filter has likely reached a level that warrants attention.

The mesh grease filter sits in the airflow path of the hood and captures airborne grease particles produced during cooking. Over time, accumulated grease reduces the filter's ability to pass air freely, which can compromise the hood's ventilation efficiency and, if left unaddressed, create a potential fire hazard. Regular cleaning of the mesh filter is critical to keeping the blower motor from working harder than necessary and to maintaining safe operation of the hood.

To reset the FG alarm after the filter has been cleaned or inspected, press and hold the Delay button for approximately 5 seconds. The hood will flash FF to confirm the reset has been accepted. Performing this reset without actually cleaning the filter does not resolve the underlying maintenance need; it only clears the timer so the counter can begin a new cycle. Technicians should confirm the filter has been properly cleaned before resetting to ensure accurate tracking of future maintenance intervals.
