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. • The filter replacement light has been on continuously but you did not
replace the corresponding filter, it is now locked. In this case, replace the
filter and reset the filter time.
• The water refill light flashes. Make sure the water tank is properly
installed.
The appliance does not
work even though it is
switched on. The appliance is working but the buttons are not responsive. Check is the
child lock is on (for AC4081 only).
The water tank leaks. It is normal that the lid of the water tank is slightly wet when you remove it
from the appliance. However, if water drops keep dripping from the bottom of
the water tank, contact the Consumer Care Center in your country.
There are some
white deposits on the
humidification filter. The white deposits are called limescale and they consist of minerals from
the water. Limescale on the humidification filter affects the humidifying
performance. Therefore you have to descale the humidification filter when
the filter light / flashes (See the chapter "Clean the pre-filter and
descale the humidification filter").
No air comes out of
the air outlet. Plug the appliance into the power supply and switch on.
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 "Clean the
pre-filter and descale the humidification filter").
• Make sure that you have removed all packaging material from the filters.
The air quality does
not improve, even
though the appliance
has been operating for
a long time. • 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) filter 2; 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 "Clean the air quality sensor").
