2. FEATURES & TECHNICAL EXPLANATION 2-1.FEATURES Anti - Crease Function With the alternate rotation of the drum, creasing in the laundry is minimized. More economical by Fuzzy Logic System FUZZY Logic System detects the amount of load and water temperature, and then determines the optimum water level and washing time to minimize energy and water consumption.
2-2.DETERMINE WASHING TIME BY FUZZY LOGIC To get the best washing performance optimal time is determined by sensing of water temperature, selected washing temperature and laundry amount. water temperature washing time selected washing temperature FUZZY LOGIC rinse time the best washing performance spin rhythm, time laundry amount SENSING PROCESSING DETERMINATION EFFECT 2-3.WATER LEVEL CONTROL This model adopts a pressure sensor which can sense the water level in the tub.
3. PARTS IDENTIFICATION Power plug If the supply cord is damaged, it must be replaced by the manufacturer or its service agents or a similarly qualified person in order to avoid a hazard.

7. TROUBLESHOOTING 7-1. BEFORE PERFORMING SERVICE ■ Be careful of electric shock or disconnecting the parts while troubleshooting. ■ Voltage of each terminal in 220-240V~ and DC while applying an electric current. 7-2. QC TEST MODE. ① Pressing Option and Time button simultaneously. ② Power supply ON with pressing upper two button. ③ Press the START/PAUSE button as follows.
7-5.ERROR DISPLAY. ¥ If you press the [Start/Pause] button when an error is displayed, any error except S/W ERROR will disappear and the machine will change into pause status. ¥ In case of , , , if the error is not resolved within 20 sec. In the case of other errors, if the error is not resolved within 4 min. power will be turned off automatically and the error code will be blinked. But in case of , power will not be turned off.
8. ERROR DIAGNOSIS AND CHECK LIST 8-1.DIAGNOSIS AND ANSWER FOR ABNORMAL OPERATION SYMPTOM NO POWER GUIDE FOR SERVICE CALL Is the power plug connected firmly to 220-240V~ outlet? YES Power failure? or Breaker opened? Is the outlet controlled by a switch.
SYMPTOM DOOR OPEN ERROR Refer to 7-3 ERROR DISPLAY GUIDE FOR SERVICE CALL Did you press the Start/Pause button when the door is open? YES Close the door NO Visit to check Check if the door switch is O.K Drain Trouble Is displayed? YES Is the debris filter clogged with foreign material such as pins, coins, etc.? NO Is the drain hose frozen with water, kinked, or crushed? NO Visit to check 16 YES Clean up the filter.
SYMPTOM Suds overflow from the appliance. GUIDE FOR SERVICE CALL Is low-sudsing detergent for the durm washing machine used? (In this condition, wash and YES spin do not operate normally) Is the proper amount of detergent used as recommended? YES LOW SUDSING DETERGENT Recommend to reduce the amount of detergent. This appliance has the automatic suds sensing function which operates under much suds condition for good rinse and preventing overflow.
8-2.FAULT DIAGNOSIS AND TROUBLESHOOTING CAUTION 1. Be careful of electric shock or disconnecting the parts while troubleshooting. 2. First of all, check the connection of each part terminal with wiring diagram. 3. If you replace the PWB assembly (Main), put in the connectors correctly. NO POWER When measuring the voltage of the outlet, is the voltage AC 220-240V? NO Check the fuse NO Check the harness Assembly.
NO WATER SUPPLY Is the water supply shut-off? NO Is the tap opened? NO Open the tap. YES Clean the filter. NO Replace the inlet valve.
