Bertazzoni range hood display · also shown as F flashing, display flashes F What to do when F shows on the range hood ### Kind of code Filter reminders The hood has counted enough hours of fan time to ask for its filters: the mesh or baffle grease filters want a wash, or on a recirculating hood the charcoal filters want replacing. Most hoods count hours rather than measure grease, so the light comes on whether the filters are clean or not, and it stays on until it is reset with the key the manual names. A reminder that returns straight after a reset, or a hood that still pulls weakly with fresh filters, is worth a visit. ### Usually leads to Range hood filter and baffle service Cleaning or replacing what catches grease and odor: mesh and baffle filters, charcoal pads on recirculating hoods, and the grease channel. ### Shows up as Reading a Range Hood Error Code or Blinking Light A range hood error code may appear as letters and numbers on a display, a light that blinks in a pattern, a filter reminder that will not clear, or a beep with the fan refusing to start. ### Make Bertazzoni A Bertazzoni range hood that has stopped pulling steam is inspected in your kitchen, beginning with the rating label hidden behind its grease filters. ### Source Bertazzoni KG30X 30-inch wall hood user and installation manual Bertazzoni KG30X, KG36X and KG48X wall hoods with the digital speed display.

Switch the hood off and let the filters cool, then take them down and wash them by hand or in the dishwasher. If it comes back, it needs a visit. ### How long after cleaning will the F come back on my Bertazzoni KG hood? The control counts blower hours, so it depends on how much you cook. A hood that asks again within a week or two may have a count that did not reset, and that is worth a visit. ### Which button clears the F on a Bertazzoni KG hood? Button B, the light key. Hold it for about five seconds with the clean filters back in place until the display stops flashing. ### Can I keep cooking while the F is flashing on my Bertazzoni? Yes, the hood still runs. Grease left in the filters is a fire risk and cuts the draw, so wash them soon. --- **[Read on the site: Bertazzoni F flashing: the grease filters on a KG hood are due](https://rangehooderepair.center/error-codes/bertazzoni-f/)** **[Book a visit with RangeHoodeRepair.center](https://rangehooderepair.center/schedule/)**
