KitchenAid Vent Hood Display F: Grease filter cleaning reminder

What F means

On KitchenAid vent hoods with a display, an F shown while the fan runs is the grease filter reminder. After 30 hours of fan operation the hood tells you the metal filter needs cleaning. It is not a failure code in the sense of a broken part; it is the hood asking for maintenance. Washing the metal filter and resetting the count puts the reminder away for the next cycle.

Common causes of F

30 hours of fan operation reached
Metal grease filter holding cooking residue
Reminder not reset after cleaning

✓ One safe check you can try

1. Turn the hood off and wait for the fan to stop. 2. Slide out the metal grease filter. 3. Wash it in warm soapy water or the dishwasher if the filter allows. 4. Let it dry and refit it. 5. Press and hold FAN for 3 seconds to reset. If F returns immediately, call us.

! Why to stop there

The reminder itself needs no repair, only cleaning.
If F returns right after a reset, the control that keeps the count should be tested.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

FF questions

How often does F appear?

The hood shows F after 30 hours of fan operation, and it stays on while the fan runs. It is the cue to wash the metal grease filter rather than a sign of damage.

How do I clear F?

Clean the metal filter, let it dry, and put it back. Then press and hold FAN for 3 seconds. The count restarts and the F disappears from the display until the next 30 hours.

Is F the same as the C reminder?

No. F is for the metal grease filter at 30 hours of fan use, while C is for the charcoal filter at 120 hours. Each has its own page and its own cleaning step.
