7. TEST MODE

7-1. SAFETY CAUTION

There’s built-in AC 120V and DC power in output terminal of PWB assembly in common. 
Be careful electric shock when disconnecting parts while trouble shooting. (Wear Electro
Static Discharge gloves when working.)
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.

7-3. HOW TO CHECK THE WATER LEVEL FFREQUENCY

1. Press the SPIN SPEED and SOIL LEVEL buttons simultaneously.

Press the WASH/RINSE and DELAY WASH button simultaneously.

The digits indicate the water level frequency ( x.1 kHz ).

=  24.1 kHz

So, for example a display indicating 241: a Water level frequency of 241 x.1 kHz

2. Press the Power      button, while the above condition. Then buzzer will sound twice.
3. Press the Start/Pause      button repeatedly to cycle through the test modes.

8. TROUBLESHOOTING

If you press the START/PAUSE button when an error is displayed, any error except            will
disappear and the machine will go into the pause status.
In case of            ,           ,            if the error is not resolved within 20 seconds, or the in 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          , power will not be turned off.

8-1. SAFETY CAUTION

There’s built-in AC 120V and DC power in output terminal of PWB assembly in common. Be careful
electric shock when disconnecting parts while trouble shooting. (Wear Electro Static Discharge gloves
when working.)
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.

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).

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.

8-2. ERROR MODE SUMMARY

LOCKED MOTOR

ERROR

EEPROM ERROR

• The connector (3-pin, male, white) in the MOTOR

HARNESS is not connected to the connector (3-pin,

female, white) of STATOR ASSEMBLY.

• The electric contact between the connectors (3-pin,

male, white) in the MOTOR HARNESS and 4-pin,

female, white connector in the MAIN PWB

ASSEMBLY is bad or unstable.

• The MOTOR HARNESS between the STATOR

ASSEMBLY and MAIN PWB ASSEMBLY is cut

(open circuited).

• The hall sensor is out of order/defective.

• EEPROM is out of order.

Displayed only when the START/PAUSE button is

first pressed in the Load Test Mode.

POWER FAILURE

• After the power supply is stopped while washing

machine is working, the power is supplied rapidly.
