Troubleshooting And Fault Codes - Meaco DD8L Zambezi Instruction Manual

9. TROUBLESHOOTING AND FAULT CODES

If Zambezi displays C1, C2, C3, C4 or if the temperature and relative humidity readout continuously flickers then consult
your Meaco approved after sales service centre.
Problem
The unit does not work.
The device does not
dehumidify.
The dehumidifier works,
but reduces the relative
humidity
insufficiently/there is little
water in the water tank.
The windows were clear
and now condensation
has returned.
I cannot remove the
condensation from my
windows, even in 40%rh
mode.
Dehumidifier is blowing
out warm air.
Knocking noise coming
from the dehumidifier
Water not draining down
the hose
Dehumidifier leaks water
onto the floor
Machine not switching off
and on in the usual 30
minute pattern
Unit only works in
Laundry mode and
Laundry light stays on or
flashes.
Cause
The power is not connected.
The water container is full.
The water container has not been replaced correctly.
The air filter is clogged.
The temperature in the room where the dehumidifier is
operating is too low.
The relative humidity in the room where the dehumidifier
is operating is too low.
The house is too large. This dehumidifier can dry up to
about a small five bedroom house.
There are too many sources of moisture. Bathing,
washing, drying clothes and cooking all puts moisture into
the air. Portable gas heating can add too much moisture
into the air for a dehumidifier.
There is too much ventilation.
The air filter is blocked and the reduce air flow is effecting
performance.
The outside air temperature has dropped and the
windows are colder.
The surface temperature of the windows is too low for a
dehumidifier to prevent condensation. Common with
single glazed windows and when the outside air
temperature drops below freezing.
The dried air is past over a heating element before it is
blown into the room as part of the dehumidification
process.
Motor that rotates the desiccant wheel is low on
lubrication.
Hose is fitted for continuous drainage but the water still
goes into the tank.
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.
Temperature and relative humidity sensor that reads the
room reading is unable to read the correct readings.
If the humidity sensor is faulty then the dehumidifier will
only run in Laundry mode.
Solution
Insert the plug into the wall outlet.
Remove the water from the container.
Place the water container in the correct position.
Clean the air filter.
The machine does not dehumidify below 1°C, it is highly
unlikely at that temperature that there is any moisture to
remove anyway.
The dehumidifier dries down to the target relative
humidity set and then goes into fan only mode until the
relative humidity goes above the set point again.
We recommend using a dehumidifier with a greater
capacity.
We recommend using a dehumidifier with a greater
capacity. Consider using a different heat source to a
portable gas heater.
Reduce ventilation (e.g. close windows and shut doors.)
Clean the air filter.
Set the dehumidifier to a lower target relative humidity so
that there is less moisture in the air. Increasing the fan
speed will also increase the amount of water collected.
Keep running the dehumidifier on 40%rh 24 hours a day
and when the air temperature outside increases the
windows should clear of condensation.
Increasing the fan speed will also increase the amount of
water collected.
This is normal, a dehumidifier is not an air cooler.
Run the dehumidifier in Laundry mode for two days to
increase the lubrication, if fault persists then call Meaco.
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.
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.
Clean away any dirt that is blocking the water as per
section seven.
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.
Try clearing the sensor as per above line, if that fails then
call Meaco for a repair.
