Switch the hood off, open each filter latch and fold the filter down, supporting it from below so trapped grease does not drip. If it comes back, it needs a visit. ### How often will a Bosch wall hood ask me to clean the grease filters? Every 30 hours of fan time. Bosch also asks for the filters to be cleaned at least every two months, whichever comes first. ### Can Bosch mesh filters be machine washed? Yes, placed loosely rather than jammed in, and not alongside very dirty dishes. Some discoloration after a dishwasher cycle is normal. ### Which key clears the grease filter message on a Bosch hood? Hold the plus key for five seconds. The minus key held the same way clears the charcoal filter message instead. --- **[Read on the site: Bosch "clean grease filter": the wall hood's display has counted 30 hours](https://rangehooderepair.center/error-codes/bosch-clean-grease-filter/)** **[Book a visit with RangeHoodeRepair.center](https://rangehooderepair.center/schedule/)**
