Wolf Cooktop Error Code FG

FG is a Mesh Filter alarm on Wolf Black Hood ventilation systems, indicating the mesh grease filter needs cleaning or inspection. It is a maintenance reminder, not a mechanical fault. The code appears after the hood accumulates a set number of operating hours. Cleaning the filter and holding the Delay button for 5 seconds will reset the alarm.

You can continue cooking while the FG alarm is active, but it is important to address the filter cleaning promptly. A heavily grease-loaded mesh filter reduces airflow efficiency and can pose a fire risk over time. Cleaning the filter as soon as the alarm appears is the safest course of action.

In most cases, the FG alarm requires no parts and no professional service, just a thorough cleaning of the mesh grease filter. If the filter is damaged and needs replacement, part costs typically range from a modest amount to a higher figure depending on the specific model. If you choose to have a technician perform the cleaning and reset, expect to pay a standard service call fee in the range of $75 to $150 or more depending on your location.

Remove and clean the mesh grease filter to remove accumulated grease buildup. Once the filter is clean and reinstalled, press and hold the Delay button for approximately 5 seconds to reset the alarm. The hood will flash FF to confirm the reset was successful. If the alarm returns quickly, check that the reset was completed properly and that the filter is fully seated.

Holding the Delay button for 5 seconds will clear the FG alarm and reset the usage timer, but if the filter has not actually been cleaned, the underlying grease buildup remains. Resetting without cleaning only restarts the tracking cycle and does not address reduced airflow or fire risk. Always clean the filter before performing the reset.
