8 Troubleshooting
This chapter summarizes the most common problems you could encounter
with the appliance. If you are unable to solve the problem with the information
below, contact the Consumer Care Center in your country.
Problem Possible solution
The appliance
does not work
even though it is
plugged in. • 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 airflow that
comes out of
the air outlet
is significantly
weaker than
before. • The pre-filter is dirty. Clean the pre-filter (see the
chapter "Cleaning").
The air quality
does not improve,
even though the
appliance has
been operating
for a long time.
•
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 Pro S3 (FY4152); 2) 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 color of the
air quality light
always stays the
same. • The air quality sensor is dirty. Clean the air quality
sensor (see the chapter "Cleaning").
