Symptom
Cause/Remedy
The unit blows warm air
Water does not collect in
the water tank (minimal
dehumidifying results)
The unit does not operate
(no air comes out)
The unit stops
The humidity level does
not reach the level set
The unit continues to operate

Louvre does
not swing
Stops after a
short time
¡
Dehumidified air passes through heating coils causing it to
warm (this unit is not a cooler). This is not a malfunction.
¡
Check to see if the temperature/humidity is low.
Low room temperature/humidity reduces dehumidifying
effectiveness. Confirm the current humidity reading (in winter,
the air is dry reducing dehumidifying effects to zero). This is
not a malfunction.
¡
Check to see if the power cord is correctly plugged.
➝
Plug the power cord properly into the power socket.
¡
Check to see if anything is blocking the air intake or outlet.
➝
Remove the obstruction.
¡
Is the unit operating in LAUNDRY mode?
➝
The unit may stop after a short time depending on the room
temperature/humidity in this mode.
¡
Check to see if the pre-filter is clogged.
➝
Clean according to the maintenance procedures.
¡
Check to see if the unit is in EASY DEHUMIDIFYING, MILDEW
GUARD, or AUTO.
The unit is automatically controlling the dehumidifier, fan, and standby times.
¡
Check to see if the water tank is full.
➝
Empty the water tank and return it to its original position.
¡
Check to see if the water tank is inserted properly.
➝
Adjust the position of the water tank.
¡
Is the unit set to internal drying mode?
This function activates automatically after ending operations.
¡
Check to see if the unit is in defrosting mode.
The unit activates defrosting mode when the room
temperature drops below 15
°
C. The dehumidifier and blower
functions stop during defrosting.
¡
Check to see if the room is not too large.
➝
Use within effective boundaries (floor space).
¡
Check to see if the exits to the room are open.
➝
Refrain from opening doors/windows during operation.
¡
Check to see if steam producing appliances such as
kerosene heaters are on in the vicinity.
¡
Hygrometer readings differ from place to place even if in the
same room. Use the unit humidity reading as an estimate.
¡
Press the Swing louvre switch again.
¡
The residue is from final product testing at the factory. It is not
a result of a malfunction.
¡
The residue is from debris in the air.
➝
