1. When the above fault cannot be eliminated and it is confirmed that repair is required,
please contact the LUBAIR support, please do not disassemble the machine for repair without authorization.
2. When the dehumidifier is running or stopped, it is normal to hear the sound of refrigerant circulating.
3. It is normal for hot air to be discharged from the air outlet.
Fault
Cause Solution
Dehumidifier
not working
1.The fuse is blown
2.Machine failure prompt
1.Replace the fuse;
2.Query the fault code
and request the
manufacturer's
technical support;
Dehumidifying
effect is not
obvious
1.Air filter fouling;
2.There are obstacles in
the air inlet and outlet
of the dehumidifier;
3.The space is not sealed;
4.Refrigerant leakage;
1.Clean the filter;
2.Remove obstacles;
3.Close the doors and
windows, the
dehumidification effect
of the confined space is
more obvious;
4.Contact the agent or
manufacturer for
maintenance;
Water leakage
1.Machine tilt;
2.The outlet pipe is Blocked;
1.Adjust the machine and
place it horizontally;
2.Remove the access door
to remove the foreign
matter blocked in the pipe;
Abnormal noise
1.The machine is not placed
smoothly;
2.Is the filter blocked;
1.Relocate the machine to
a stable place;
2.Clean the filter;
Humidity always
shows "10"(when
there is a big
difference from the
actual humidity)
Humidity sensor failure
1.When the "10" fault
phenomenon is always
displayed, the humidity
is set to 10%RH, and the
machine can still continue
to run and be used normally;
2.Repair and replace the
humidity sensor;
Humidity always
shows "99"(when
there is a big
difference from the
actual humidity)
1.The surface of the humidity
sensor os condensed or
wetted with water;
2.Humidity sensor failure
1.When the "99" fault phenomenon
is displayed all the time, the machine
can still continue to dehumidify and
operate normally;
2.After the machine has been running
for a period of time, when the moisture
on the surface of the humidity sensor
dissipates,ig can automatically remove
the fault and resume normal operation;
3.Repair and replace the humidity
sensor;
