Wolf Hood Error Code FG

FG is a mesh filter alarm on Wolf hoods, indicating the mesh grease filter has reached its cleaning interval based on cumulative fan runtime. It is a maintenance reminder, not a component failure. The filter should be removed and cleaned, then the alarm reset using the appropriate button hold sequence for your hood model.

Continued use with a heavily saturated grease filter carries some risk. A grease-clogged filter restricts airflow, reduces the hood's ability to capture cooking vapors, and can become a fire hazard if exposed to high heat or flame. Cleaning the filter promptly when the FG alarm appears is the safest course of action.

In most cases, the FG alarm requires only cleaning the existing mesh filter, which costs nothing beyond household supplies like dish soap and warm water. If the mesh filter is damaged and needs replacement, a new Wolf mesh grease filter typically ranges from around 20 to 60 dollars depending on the hood model and filter size. No service call is needed to address this alarm in most situations.

After cleaning the mesh grease filter, reset the alarm by holding the Delay button for 5 seconds if you have a Black hood model, or holding the Filter button for 5 seconds if you have a Stainless or Glass hood model. The alarm should clear once the hold is completed. If it does not clear, confirm you are holding the correct button for your specific hood finish.

Resetting the alarm without cleaning the filter will clear the indicator temporarily, but the underlying issue of grease accumulation remains. The alarm will return again as runtime continues to accumulate, and the filter will continue to restrict airflow and pose a potential fire risk. Cleaning the filter before resetting is strongly recommended.
