Questions people ask about FF

What does FF mean on a Wolf hood?
FF is a filter alarm reset confirmation message displayed on Wolf Black Hood models. It appears after the filter alarm has been successfully reset and indicates the usage timer has restarted. This is not a fault code and does not indicate any problem with the hood.
Is it safe to use my Wolf hood when FF is displayed?
Yes, the hood is safe to use when FF is displayed. FF is a confirmation message, not a warning or fault condition. As long as your grease filters have been cleaned or replaced before performing the reset, the hood is ready for normal operation.
Will resetting the filter alarm clear the FF display on a Wolf hood?
Yes, completing the filter alarm reset procedure is precisely what causes the FF display to appear. FF is the confirmation that the reset was accepted by the control board. Once FF clears, the filter usage timer begins counting again from zero.
Do I need to do anything to clear the FF display on my Wolf hood?
No action is required to clear the FF display. It will disappear on its own after a brief period or when you interact with the hood controls normally. It is simply confirming that your filter alarm reset was successful.
How much does it cost to fix an FF code on a Wolf hood?
There is no repair cost associated with the FF code because it is not an error. If the filter alarm was triggered because filters needed cleaning, the only potential cost would be for replacement grease filters, which typically range from around $20 to $80 depending on the model and filter type.
