Problem
Cause
Solution
Knocking noise
coming from the
dehumidifier
Motor that rotates the desiccant wheel is low on
lubrication.
Run the dehumidifier in Laundry mode for two
days to increase the lubrication, if fault persists
then call Meaco.
Alarm light on
continuously
Restricted airflow to the dehumidifier or
temperature below freezing.
Clean the filter and make sure that the unit is
more than 30cm from a wall. If the temperature
is below freezing then use the dehumidifier when
the space warms up again.
Alarm light flashing
Restricted airflow to the dehumidifier.
Clean the filter and make sure that the unit is
more than 30cm from a wall.
Water not draining
down the hose
Hose is fitted for continuous drainage but the
water still goes into the tank.
Negative air pressure in the room is pulling the
water back into the dehumidifier overflow. Insert
a 4mm hole into the top of the tube 30mm down
from the spout. This will introduce air into the
tube and balance out the air pressure.
Dehumidifier leaks
water onto the floor
Usually means that the dehumidifier is not on a
level surface or that the filter has not been cleaned
often enough and dirt has fallen into the
dehumidifier.
You can also check that the water bucket is not
cracked by filling it with water and placing it on
kitchen paper on the kitchen side.
Machine not switching
off and on in the usual
30 minute pattern
Temperature and relative humidity sensor that
reads the room reading is unable to read the
correct readings.
Clean the filter and blow the air sensor with a hair
dryer on fast setting to clear the sensor of dirt.
Unplug the dehumidifier for 10 minutes to reset it’s
circuits and then turn back on.
Unit only works in
Laundry mode and
Laundry light stays on
or flashes.
If the humidity sensor is faulty then the
dehumidifier will only run in Laundry mode.
Try clearing the sensor as per above line, if that
fails then call Meaco for a repair.
Medium fan speed
light flashes
None of the buttons work.
This is normal and the unit is functioning ok. The
unit will return to normal operation when
conditions allow. More details below.
If one of the following events happens then the control panel will lock up and the fan light will flash.
Temperature below 10°C
Temperature above 40°C
Relative humidity below 40%rh
Machine has been working hard and needs to cool down internally.
If you find that this happens and you none of the buttons on the control respond then do not worry, this is
normal and the dehumidifier will start to work again when the conditions allow.
