(4) Maintenance for water pump and water pipe
Check here.
Water
supply
pipe
Water pipe · Tank holder
1. Pull out water supply
pipe. Wipe the tank
holder with clean cloth.
•Do not let water flow into
the tank holder. packing
2. Separate pieces and wash with water.
Light-type bacteria removing filter
Water pump
1. Pull out the pipe. 2. Turn the tank
pump to detach.
5. Put the parts back in the reverse order of disa-
ssembly.
3. Pull out the tank pipe, turn the cap
to remove, and then wash
the propeller with water.
•The propeller is
made of the magnet.
Wash it well with water
so that no alien sub-
stance remains on it.
4. Remove the light-type bacteria removing filter
and wash it in water.
Normally the filter need not be replaced. However, replace it
in the following condition:
•When the filter is clogged by passing something other than
water through the filter.
•When the filter is broken.
In such a case, contact the dealer that you purchased this

W
ater or ice is
on the ice tray
The ice-maker gear box may be defective, cooling may be poor or ice cubes may be full in the server.
3.Check if the temperature of the freezer com-
partment is cool enough.
(It takes longer to make ice during summer
time or if the door is frequently opened.)
2.Measure the resistance of ice tray thermistor
circuit.
1.Check inside of the ice server.
The water saucer may be defective, or the ice tray may get cracked.
4. Check the water pipe between the refrigerator
compartment and freezer compartment for dirt,
and foreign objects.
5.Check the condition of ice tray.
6.Disassemble the water pump and check the
inside of the pipe.
7.Tank pipe is clogged , has a hole or is not
properly installed.
8.Check the motor coil resistance.
9.Check if there are any dirt or foreign object
which are difficult to remove in the water tank.
Also, check if there is any crack or deformation
on the tank.

10.Check the water pipe for dirt, and foreign
objects. Also, check the water pipe position and
connection.
11.Check the water pipe (between F.compartment
and R.compartment) for clogging.
12.Check the water pump operation by the ice-
making test.
13.Water spill at the installation of water tank or more water over the full water level may cause to from
chained ice.
14.Measure the water pump coil resistance.
• Ice cubes are not stored flatly
and the amount is detected as
full.
• Food inside the ice server
•Open circuit ( ∞ ' ) or
short circuit (0 ' )
•Not enough
