Problem Possible solution
No air comes out of the
air outlet.
Put the plug of the appliance into the power supply and switch on.
The fan speed does not
change when the silent
mode is activated.
In silent mode, the fan speed is set to a very low level. If you want to
change the fan speed and leave the silent mode, press the SPEED button
once or more times to set the desired fan speed.
The airow that comes
out of the air outlet is
signicantly weaker than
before.
• The pre-lter is dirty. Clean the pre-lter (see the chapter ‘Clean
your appliance’, section ‘‘Clean the pre-lter and humidication
lter’).
• Make sure that you have removed all packaging material from the
lters.
The air quality does not
improve, even though
the appliance has been
operating for a long time.
• One of the lters has not been placed in the appliance. Make sure
that all lters are properly installed in the following order, starting
with the innermost lter: 1) HEPA lter, 2) activated carbon lter, 3)
Multi-care lter, and 4) pre-lter.
• 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 your appliance’, section ‘‘Clean
the air quality sensor and air humidity sensor’).
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 “Clean your appliance’, section ‘Clean the air quality sensor
and air humidity sensor’ under).
• There is not enough ventilation in the room. Open a window, to
improve the air circulation.
I do not see water
vapor coming out of the
appliance. Is it working?
When water vapor is very ne, it is invisible. This appliance has a specially
designed humidication lter that produces very ne water vapor.
Therefore, you cannot see the water vapor.
I want to check whether
the air humidity sensor
works or not.
Remove the cover of the air quality/humidity sensors and then
gently blow moist air into the opening. After a while, the CURRENT
HUMIDITY indication changes. Note that if the initial CURRENT
HUMIDITY indication is already 60%, the indication cannot show an even
higher humidity when you blow moist air towards the sensor.
