7 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.
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:
• 25 m
/269 ft (HU4803)
2 2
• 44 m
/474 ft (HU4813)
2 2
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.
