7 Troubleshooting
This chapter summarizes the most common problems you could encounter with the
humidier. If you are unable to solve the problem with the information below, contact the
Consumer Care Center in your country.
Problem Possible solution
The humidier does
not work.
• Make sure that there is power supply to the humidier.
• Make sure that the water tank is lled with water and the
upper unit is placed properly onto the water tank.
There is no air
humidication.
• Make sure that the water tank is lled with water and the
upper unit is placed properly onto the water tank.
• The humidier will stop working if the current humidity
level reaches 70%RH. Humidity level above 70%RH
does not make users feel comfortable, so the humidier
automatically turns o to ensure optimal humidication
performance.
The water tank leaks. • Make sure that the humidier is not overlled with water.
• Make sure that the humidier is well assembled/connected
every time after you clean it or after you remove the upper
unit and/or water tank for relling.
• Make sure that the water tank is properly placed. If the
problem persists, contact the Consumer Care Center in
your country.
I do not see the
current humidity
indication change.
• Make sure that you have assembled the humidication
lter round the lter support.
• The humidication lter is dirty. Rinse and/or descale
the humidication lter (see the chapter ‘Clean the
humidication lter’).
• Your room might have too much ventilation. Please close
doors and windows.
• Your room size is too big. The recommended room size is:
• 25 m2/269 ft2(HU4803)
• 44 m2/474 ft2 (HU4813)
There are some white
deposits on the
humidication lter.
The white deposits are called scale and they consist of
minerals from the water. Scale on the humidication lter
aects the humidifying performance, however it does not
harm your health. Please follow the cleaning instructions in
the user manual.

12
EN
Problem Possible solution
The lter turns
yellowish after some
time.
The yellow deposits is a natural eect of the wick material,
and it has no impact on humidication performance. Clean
the humidication lter frequently to remove the scale, and
replace the humidication lter every 6 months.
There is unpleasant
smell coming out from
the humidier.
• Make sure that the water tank is lled with water.
• Clean the humidication lter (see the chapter ‘Clean the
humidication lter’).
No air comes out of
the air outlet.
Put the plug of the humidier into the wall socket and switch
on the humidier.
I do not see visible
mist coming out of
the humidier. Is it
working?
When mist is very ne, it is invisible. This humidier has a
NanoCloud humidication technology, which produces
healthy humid air from the outlet area without formation of
water mist. Therefore, you cannot see the mist.
I want to check
whether the humidity
sensor works or not.
Gently blow moist air into the humidity sensor. After a while,
the humidity indication changes. The indication can show the
ambient humidity level from 20%RH to 95%RH.
The humidier still
works even when
environment reaches
target humidity.
The humidier will turn on at intervals, in order to ventilate air
around humidity sensor, therefore get more accurate reading
on environment humidity. This setting applies to the humidity
level setting, including the Auto mode.
