8 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.

There are some white deposits on the humidification filter.	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 filter turns yellowish after some time.	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.

Problem Possible solution

There is unpleasant smell coming out from the humidifier.	Make sure that the water tank is filled with water.Clean the humidification filter (see chapter ‘Cleaning the humidification filter’).
No air comes out of the air outlet.	Put the plug of the humidifier into the wall socket and switch on the humidifier.
I do not see visible mist coming out of the humidifier.Is it working?	When mist is very fine, it is invisible. This humidifier has a NanoCloud humidification technology, which produces healthy humid air from the outlet area without formation of water mist.Therefore, you cannot see the mist.
