OPERATIONS

The compressor will start to work after the fan works for a few seconds.

The compressor will shut down at once and the fan will stop after a few 
seconds (when other malfunctions occur or humidity reaches the desired 
level, the fan will stop after ten seconds).

Tips: The compressor features "3 minutes delay protection" function 
While the dehumidifier is powered,  the compressor can only start again 
three minutes after its last shutdown.

Does the humidity sensor fail?

Is there some water on the 
surface of the humidity sensor?

Set the humidity to 30% RH and check 
if the dehumidifier can work normally. 
If it does, the machine is in a good 
condition.

Repair or replace the humidity sensor.

The dehumidifier can work normally. 
The moisture removal effect is not 
affected.

Please keep the machine working for 
a while to remove the water on the 
humidity sensor surface. The machine 
will work normally when the water is 
removed.

Repair or replace the humidity sensor.

Humidity always shows 
"25% RH" but there is a
