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 25m²
for both HU4802 and HU4803.
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').
