Troubleshooting

This chapter summarizes the most common problems you could encounter with the humidifier. If you are
unable to solve the problem with the information below, contact the Consumer Care Center in your country.
Problem
The humidifier does not
work.
There is no air
humidification.
The water tank leaks.
I do not see the current
humidity indication change.
There are some
white deposits on the
humidification filter.
The filter turns yellowish
after some time.
There is unpleasant smell
coming out from the
humidifier.
Possible solution
• Make sure that there is power supply to the humidifier.
• Make sure that the water tank is filled with water and the upper unit
is placed properly onto the water tank.
• Make sure that the water tank is filled with water and the upper unit
is placed properly onto the water tank.
• The humidifier will stop working if the current humidity level reaches
70%RH. Humidity level above 70%RH does not make users feel
comfortable, so the humidifier automatically turns off to ensure
optimal humidification performance.
• Make sure that the humidifier is not overfilled with water.
• Make sure that the humidifier is well assembled/connected every time
after you clean it or after you remove the upper unit and/or water
tank for refilling.
• Make sure that the water tank is properly placed. If the problem
persists, contact the Consumer Care Center in your country.
• Make sure that you have assembled the humidification filter round the
filter support.
• The humidification filter is dirty. Rinse and/or descale the
humidification filter (see the chapter 'Clean the humidification filter').
• Your room might have too much ventilation. Please close doors and
windows.
• Your room size is too big. The recommended room size is 25m
The white deposits are called scale and they consist of minerals from
the water. Scale on the humidification filter affects the humidifying
performance, however it does not harm your health. Please follow the
cleaning instructions in the user manual.
The yellow deposits is a natural effect of the wick material, and it has no
impact on humidification performance. Clean the humidification filter
frequently to remove the scale, and replace the humidification filter every
three month.
• Make sure that the water tank is filled with water.
• Clean the humidification filter (see the chapter 'Clean the
humidification filter').
