Possible solution
• Check if the top cover is properly installed.
• The filter replacement light has been on continuously
but you have not replaced the corresponding filter. As a
result, the appliance is now locked. In this case, replace
the filter and reset the filter lifetime counter.
• The pre-filter is dirty. Clean the pre-filter (see the
chapter "Cleaning").
• Check if the packing material is removed from the
filters.
• One of the filters has not been placed in the appliance.
Make sure that all filters are properly installed in the
following order, starting with the innermost filter:
1) NanoProtect filter Series 3 (FY3433);
2) NanoProtect filter Active Carbon (FY3432);
3) pre-filter.
• The air quality sensor is wet. The humidity level in your
room is high and causes condensation. Make sure that
the air quality sensor is clean and dry (see the chapter
"Cleaning").
• The air quality sensor is dirty. Clean the air quality
sensor (see the chapter "Cleaning").
