Switch the hood off and remove the grease filters. If it comes back, it needs a visit. ### How often will my La Cornue Château hood flash for its filters? Every 30 hours of running. A busy kitchen can see it every couple of weeks. ### Which button resets the flashing on a La Cornue hood? The run-on timer push button, the one that runs the blower on for ten minutes to clear fumes. ### Is the island Château hood the same? Yes, La Cornue's island hood guide describes the same 30-hour signal and the same reset. --- **[Read on the site: La Cornue six indicators flashing: Château hood grease filters are due](https://rangehooderepair.center/error-codes/la-cornue-six-lights-flashing/)** **[Book a visit with RangeHoodeRepair.center](https://rangehooderepair.center/schedule/)**
