If the LEDs / lights flash on the hood's display it indicates that a filter and / or carbon filter should be washed.
- Ensure that the filter is clean, otherwise follow the instructions in the user manual.
- If the filter is clean, the filter timer must be reset so that the lamps stop lighting / flashing.
- Find more information in the user manual. (If you do not have your user manual, refer to Where can I find the user manual for my appliance?).
