FEATURES & TECHNICAL EXPLANATION

FEATURES

	Direct Drive System The advanced Brushless DC motor directly drives the drum without belt and pulley.
	Tilted Drum and Large Door Opening Tilted drum and large opening make it possible to load and unload clothing more easily.
	Time-Released Dispenser Detergent, fabric softener and bleach are dispensed separately at the right time during wash cycle.
	Automatic Wash Load Detection Automatically detects the load and optimizes the washing time.
	Child Lock The Child lock prevents children from pressing any button to change the settings during operation.

NEURO FUZZY WASHING TIME OPTIMIZATION

To get the best washing performance, optimal time is determined by the water temperature, the selected washing temperature, and the size of the load.

WATER LEVEL CONTROL

• This model incorporates a pressure sensor which can sense the water level in the tub.
• The water supply is stopped when the water level reaches the preset level, the washing program then proceeds.
• Spinning does not proceed until the water in the tub drains to a certain level.

DOOR CONTROL

• The door can be opened by pulling the door handle whenever washer is not in operation.
• When the cycle is completed, the DOOR LOCKED light will turn off.
• If a power failure has occurred while in operation, the door will unlock after 5 minutes.
• Clicking sounds can be heard when the door is locked/unlocked.

THE DOOR CAN NOT BE OPENED

• While program is operating
• When a power failed and power plug is taken out in operation
• While Door Lock lights turn on.
• White the motor is in the process of intertial rotating, through the operation is paused.

DOOR LOCKED LAMP LIGHTS

• When the frequency of water level is lower than 22.9 kHz
  (It can be canceled when the frequency is more than 23.8 kHz)
• When the temperature inside the tub is higher than 45°C and water level is not 25.5 kHz
  (It can be canceled when the water level is 25.5 kHz or the temperature inside the tub is lower than 40°C)

CHILD LOCK

• Use this option to prevent unwanted use of the washer. Press and hold OPTION button for 3 seconds to lock/unlock control.
• When Child lock is set, " " blinks and all buttons are disabled except the Power button. You can lock the washer while it is operating.

5. Check the automatic reverse rotation.
   
   • Check if the drum rotates clockwise and counterclockwise.
6. Check the water temperature.
   
   • Press the WASH/RINSE button and the present temperature will be displayed.
7. Check the drain and spin functions.
   
   • Power off and the power on.
   • Press the SPIN SPEED button.
   • Press the START/PAUSE button.
   • Check the spin and drain functions.
8. Press the START/PAUSE button.

TROUBLESHOOTING

BEFORE PERFORMING SERVICE

• Be careful of electric shock when disconnecting parts while troubleshooting.
• The voltage of each terminal is 120 V AC and DC when the unit is plugged in.

QC TEST MODE

The washer must be empty and the controls must be in the off state.

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

4. ¹⁾ Alternate blinking of ¹⁾ and

Number of times the Start/Pause button is pressed	Check Point	Display Status

HOW TO CHECK THE WATER LEVEL FREQUENCY

• Press the Delay and Beeper button simultaneously.
  
  So, for example a display indicating 241: a Water level frequency of 241 x.1 kHz = 24.1 kHz

ERROR DISPLAY

• 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 sec., or the in case of other errors, if the error is not resolved within 4 min., power will be turned off automatically and the error code will blink. But in the case of , power will not be turned off.

	ERROR	SYMPTOM	CAUSE
1	WATER INLET ERROR		Correct water level (246) is not reached within 8 minutes after water is supplied or it does not reach the preset water level within 25 minutes.
2	IMBALANCE ERROR		The load is too small. The appliance is tilted. Laundry is gathered to one side. Non distributable things are put into the drum.
3	DRAIN ERROR		Not fully drained within 10 minutes.
4	OVER FLOW ERROR		Water is overflowing (water level frequency is over 213). *œ If is displayed, the drain pump will operate to drain the water automatically.
5	PRESSURE SENSOR ERROR		The SENSOR SWITCH ASSEMBLY is out of order. Door not all the way closed.
6	DOOR OPEN ERROR		Loose electrical connections at Door switch and PWB Assembly. The DOOR SWITCH ASSEMBLY is out of order.
7	THERMISTOR ERROR		The THERMISTOR is out order.
8	LOCKED MOTOR ERROR		The connector (3-pin, male, white) in the MOTORHARNESS 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 STATORASSEMBLY and MAIN PWB ASSEMBLY is cut (open circuited). The hall sensor is out of order/defective.
9	EEPROM ERROR		EEPROM is out of order. œ Displayed only when the START/PAUSE button is first pressed in the QC Test Mode.
10	POWER FAILURE		The washer experienced a power failure.

ERROR DIAGNOSIS AND CHECK LIST

DIAGNOSIS AND SOLUTION FOR ABNORMAL OPERATION

SYMPTOM	GUIDE FOR SERVICE CALL
No power
Water inlet trouble
Door error
Drain trouble
Suds overflow from the appliance. (In this condition, wash and spin do not operate normally)	This appliance has an automatic suds sensing function which prevents overflow. When excessive suds are sensed, the suds removing implementations such as drain, water input, pause will operate, without rotating the drum.
Liquid laundry products do not flow in.
	Visit to service.

FAULT DIAGNOSIS AND TROUBLESHOOTING

1. Be careful of electric shock if disconnecting parts while troubleshooting.
2. First of all, check the connection of each electrical terminal with the wiring diagram.
3. If you replace the MAIN PWB ASSEMBLY, reinsert the connectors correctly.

NO POWER

VIBRATION & NOISE IN SPIN

If it still has severe vibration and noise, regulate a specific spin speed that generates excessive vibration and noise as follows:

1. Put an unbalance part (rubber) inside of the drum.
2. Start the QC test mode
3. Press Delay Wash button, then ' ' is displayed.
4. Press the Spin Speed button repeatedly to select EXTRA HEIGH.
5. Press the Start/Pause button.
6. Press the Beeper button repeatedly to set spin speed (600, 700, 800, 900, 1000, 1100 rpm) and check if thereis vibration and noise.
7. If there is no vibration and noise, increase the spin speed by pressing Beeper button.
8. If there is vibration and noise, press the Cycle selector button to reduce the Spin Speed (reduce by 50 and 100 rpm). In case of 600 rpm, it can not reduce the spin speed.
9. If vibration and noise are reduced, press the WASH/RINSE button to store (2 beep sounds).

* If you want to return to factory default spin speed setting, repeat above steps except step 8).
