Possible solution
• The filter replacement light has been on continuously but
you have not replaced the corresponding filter. As a result,
the appliance gets locked. In this case, replace the filter and
reset the filter lifetime counter.
• The appliance restarts automatically and goes to the
previous mode when the power resumes.
• The pre-filter is dirty. Clean the pre-filter (see the chapter
"Cleaning").
• 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
HEPA Series 3; 2) NanoProtect filter AC; 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").
