Troubleshooting guide
Before requesting repair service, check the following list.
Air blows but
water vapor is
not produced.
Problem Solution
White dust is
forming on the
nebulizer water
tank.
Fine materials on the nebulizer space and reservoir are
harmless.
Use the appliance after cleaning the nebulizer with clean water.
Check if the spray is in ‘weak’ mode.
If underground water has been used, replace it with tap water.
Clean the nebulizer and its surrounding area.
If the water level in the reservoir is high, drain some water.
Even if the appliance is not out of order, the humidifier may not operate
normally because you are unfamiliar with the appliance or because of a
minor problem. In these cases, the following list will help you fix the
problem without the help of customer service. If the trouble continues,
contact our customer service.
Humidity Level
is low.
If underground water has been used, replace it with tap water.
Is the water in the appliance hot, cold or frozen?
(The use of water below 42.8 (6 or above 95 (35
may cause nebulizer failure.)
If the spray amount gets too small, remove the foreign
materials on the nebulizer surface.
Is the nebulizer damaged or is the lifetime of the nebulizer
expired? (The nebulizer is a consumable part.)
The humidity has
a bad smell.
Clean the inside of the appliance.
The smell comes from chlorine contained in tap water and is
harmless. (Use tap water stored for a day or water fully
cooled after boiling will reduce the smell.)
Water supply
is not
consistent. Put the water tank on the body correctly.
Fill with water to more than half the water tank.
The floor is
too wet.
Reduce the mist amount.
