What this means
The exhaust-air filter needs cleaning or replacement; this is a maintenance warning, not a component fault.
What you can check yourself
- Switch off the unit before accessing the filter.
- Vacuum-clean or replace the filter; fit a new filter at least once per year.
- Reset the filter reminder on the display after the filter has been serviced.
