Cause and Solution
This is caused by the start or stop of the compressor, which is normal.
It is recommended to use the dehumidifier indoors at a temperature from 5°C to 35°C.
Check whether the humidity is set appropriately.
Check whether the air inlet or the air outlet is dirty or blocked, and clean them in time.
Check whether the doors and windows are open. It is recommended to close the doors and
windows and turn off other ventilation equipment when the dehumidifier is operating.
Check whether there is a power failure.
Check whether the power plug has become loose.
Check whether the water tank is full or has been installed incorrectly.
Check whether the timer function is being used.
Check whether the drainage hose has become loose.
Check whether the drainage system is blocked.
Check whether the dehumidifier is on a flat surface.

Check whether the refrigerant makes sound when the compressor is turned on.
The black stains are caused by the air dust and the materials attached to the surfaces of
the evaporator and condenser. They flow into the water tank with the condensate water.
This is normal.
Directly wipe them with a paper towel. The black stains will decrease with continued use.
