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 tes\ t modes. Check PointDisplay Status None Turns on all lamps and locks the door. 1 time Tumble clockwise. rpm (42~50) 2 times Low speed Spin. rpm (55~65) 3 times High speed Spin. rpm (125~135) 4 times Inlet valve for prewash turns on. Water level frequency (25~65) 5 times Inlet valve for main wash turns on. Water level frequency (25~65) 6 times Inlet valve for hot water turns on.

HOW TO CHECK THE WATER LEVEL FREQUENCY Press the WASH/RINSE and DELAY WASH button simultaneously. So, for example a display indicating 241: a Water level frequency of 241 x.1 kHz = 24.1 kHz The digits indicate the water level frequency ( x.1 kHz ).

In case of if the error is not resolved within 20 sec., or the in case of other err\ ors, if the error is not resolved within 4 min., power will be turned off aut\ omatically and the error code will blink. But in the case of , power will not be turned off. ERROR SYMPTOM CAUSE 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. • The load is too small. • The appliance is tilted. • Laundry is gathered to one side. • Non distributable things are put into the drum.1 2 IMBALANCE ERROR • Not fully drained within 10 minutes. 3DRAIN ERROR • Water is overflowing (water level frequency is over 213).※ If is displayed, the drain pump will operate to drain the water automatically. 4OVER FLOW ERROR • The SENSOR SWITCH ASSEMBLY is out of order. 5 PRESSURESENSOR ERROR • Door not all the way closed. • Loose electrical connections at Door switch and PWB Assembly. • The DOOR SWITCH ASSEMBLY is out of order. 6DOOR OPEN ERROR • The THERMISTOR is out order. 7HEATINGERROR
17 ERROR SYMPTOMCAUSE • 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. 8 9 LOCKED MOTORERROR • The washer experienced a power failure.POWER FAILURE • EEPROM is out of order. ※ Displayed only when the START/PAUSE button is first pressed in the QC Test Mode. 10 EEPROM ERROR
18 8-1. DIAGNOSIS AND SOLUTION FOR ABNORMAL OPERATION 8. ERROR DIAGNOSIS AND CHECK LIST SYMPTOMGUIDE FOR SERVICE CALL No power Water inlet trouble Is the power plug connected firmly to 120 V AC outlet? Power failure? or Breaker opened? Is the outlet controlled by a switch? Visit to service. Is displayed? Is the tap opened? Is the tap frozen? Is the water supply shut-off? Is filter in the inlet valve clogged with foreign material? Visit to service. Clean the filter of inlet valve
19 SYMPTOMGUIDE FOR SERVICE CALL Door error Drain trouble Was the load too large? Visit to service. Visit to service.
20 SYMPTOM GUIDE FOR SERVICE CALL Suds overflow from the appliance. (In this condition, wash and spin do not operate normally) SOFTENER MAX Is a HE (High Efficiency) detergent used? Is the proper amount of detergent used as recommended? Recommend to reduce the amount of detergent. Is liquid laundry product put in the correct compartment of the dispenser? Is the cap clogged? Explain proper use of liquid laundry products. Clean the compartment. Visit to service. 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.
