What does the Saturation Indicator signal mean on a Bosch cooker hood?

The saturation indicator informs you about when the grease filter has to be cleaned and when you have to change the odour filter.

• If the grease filter has to be cleaned, then 1 flashes.
• If the odour filter needs to be replaced, then 2 flashes.

After cleaning the grease filter and/or changing the odour filter, the saturation indicator should be reset.

Resetting the Saturation Indicator

• Switch the appliance on.
• Press and hold the timer button for 3 seconds.
• The saturation indicator is reset, and 1 or 2 stops flashing.
