8 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 off
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 25m²
for both HU4802 and HU4803.
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 affects the
humidifying performance, however it does not harm your health.
Please follow the cleaning instructions in the user manual.
The lter turns yellowish after
some time.
The yellow deposits is a natural effect 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 three month.
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’).
