Turn off both the lights and the blower. If it comes back, it needs a visit. ### Why won't S1 reset on my Bertazzoni KMC hood? The reset only takes effect with the lights and blower both off first; switch both off, then hold T3 for three seconds. ### How often should filters on a Bertazzoni KMC hood be washed? Whenever S1 lights, and Bertazzoni's own schedule puts that at roughly every two months of typical use. ### Can KMC hood filters be machine-washed? Yes, the manual allows it; letting them dry fully before refitting keeps the reset reliable. --- **[Read on the site: Bertazzoni KMC canopy hood: steady S1 light](https://appliancemaintenance.center/error-codes/bertazzoni-hood-kmc-grease-filter/)** **[Book a visit with ApplianceMaintenance.center](https://appliancemaintenance.center/schedule/)**
