This may occur when the
water supply valve is
defective.
•
If the water supply valve is broken
, replace
the valve.
•
Check if the water supply is block
ed due
to an alien substance in the valve or check
if the water is supplied to the machine. If
a problem is found, take the appropriate
countermeasure.
•
Check if the water supply is block
ed due to
the water being frozen.
•
If the P
BA
Relay malfunctions, replace the
PBA.
1.
Measure the resistance of the
water supply valve.
-
Resistance
:
0.9KΩ
to
1.1KΩ
between the terminals of the
W
ater Supply V
alve.
2.
Check whether there is foreign
material in the W

This may occur when the
drain pump is defective.
•
Check if there is any alien substa
nce inside
the draining pump motor
.
•
Check the natural drain in the sam
e manner
.
•
Check if there are any incorrect connections
or broken wires.
•
If the m
achine m
alfunctions interm
ittently
when the wash tub water temperature is
high, replace the pump.
•
If the m
otor stops due to the water being
frozen in winter
, remove the frozen water
referring to the relevant repair procedures.
Check the drain pump resistance.
(Resistance
:
13.5
~
16.5
Ω)
This may occur due to
frozen water
.
Check if there is any alien
substance inside the
draining pump.
This may occur when the
main PCB is defective.

The signals between the sub
and main PBAs are not
sensed.
•
Check the wire connections and t
erminal
contacts between the sub and main PBAs.
•
Check for disconnected wires.
•
Check whether
the sub PBA
is short-circuited
because of moisture.
•
If the m
ain PBA
’s communication
circuit is
faulty
, replace it.

Incorrect wire connections
between the sub and main
PBAs.
