What All 6 indicators flashing
actually means.
The Château hood controller adds up the time the blower runs. After 30 hours of running it lights every indicator in a flashing pattern to ask for the grease filters to be cleaned, and it keeps doing so until the count is reset.

What to do when All 6 indicators flashing shows on the range hoodKind of codeFilter 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.

What not to do
Six flashing lights do not mean the remote or the blower has failed. A hood that ignores both the buttons and the remote with no lights at all is a different problem, usually the red reset switch behind the filters or the power supply.
