7-4. HOW TO CHECK THE WATER LEVEL FREQUENCY AND

VIBRATION SENSOR ERROR

***

The digits indicate the water level frequency.

* Press the WASH/RINSE and SOIL LEVEL buttons simultaneously.

For example, if the display indicates 058,
the water level frequency is 20+(58 X 0.1) = 25 8 kHz.

The digits indicate the operation of the vibration sensor.

For example, if the display 000, the sensor is working 
If the display 001, the vibration sensor has failed.

If you press the START/PAUSE button when an error is displayed, any error except       PE ERROR
will disappear and the machine will go into the pause status.
In case of       PE ERROR,       tE ERROR, 

dE ERROR if the error is not resolved within 20

seconds, or in the case of other errors, if the error is not resolved within 4 minutes, power will be
turned off automatically and the error code will blink. But in the case of       FE ERROR, power will not
be turned off.

8-1. SAFETY CAUTION

Both 120 volts AC and DC voltages are present on the main board. Be careful to avoid a shock
hazard.

After cutting off the power when changing PWB assembly, disconnect or assemble.
Be careful static when handling PWB assembly, and use Electro Static Discharge plastic pack when
delivering or keeping it.

WATER INLET

ERROR

• Correct water level (24.6kHz) is not reached within 

8 minutes after water is supplied or it does not reach

the preset water level within 20 minutes.

NO WATER SUPPLY.

CHECK TAP & HOSE.

(LGUS)1-800-243-0000

(LGCANADA)1-888-542-2623

UNBALANCE

ERROR

• The load is too small.

• The appliance is tilted.

• Laundry is gathered to one side.

• Non distributable things are put into the drum.

DRAIN ERROR

• Not fully drained within 10 minutes.

OVERFLOW ERROR

• Water is overflowing. 

(water level frequency is over 21.3kHz).

આ

If      

is displayed, the drain pump will

operate to drain the water automatically.

PRESSURE SENSOR

ERROR

• The PRESSURE SENSOR ASSEMBLY is out of

order.

• When water level frequency maintain condition of

below 10 kHz and over 30 kHz.

DOOR OPEN ERROR

• Door not all the way closed.

• Loose electrical connections at Door switch and

PWB Assembly.

• The DOOR SWITCH ASSEMBLY is out of order.

HEATING ERROR

• The THERMISTOR is out of order.

When you press both
WASH/RINSE button and

SOIL LEVEL button
simultaneously,
is the water level frequency
below 24.6 kHz?

(Refer to 7-4.)

Is filter inlet valve clogged
with foreign material?

Is the connector connected to
inlet valve assembly
disconnected or
disassembled?

Is resistance between
each terminal of INLET
VALVE ASSEMBLY

(Refer to 9-5 inlet valve
assembly.)

Clean or
replace the filter.

Check the AIR
CHAMBER
and the tube
(clogged).

Reconnect or
repair
the connector.

Replace the
INLET VALVE
ASSEMBLY.

Is       

displayed?
