Clean the metal grease filters, and on recirculating hoods fit fresh charcoal filters. If it comes back, it needs a visit. ### How do I reset the flashing keys on my Smeg KBTU? Hold On/Off for five seconds; it flashes once to confirm. ### My Smeg 9-button panel has a separate reset key. Which do I press? Hold the filter alarm reset key for about three seconds while the alarm is on. ### Does the Smeg filter alarm count time with the fan off? No, it counts actual hood operation. --- **[Read on the site: Smeg speed keys flashing: touch-panel filter alarm](https://rangehooderepair.center/error-codes/smeg-speed-keys-flashing/)** **[Book a visit with RangeHoodeRepair.center](https://rangehooderepair.center/schedule/)**
