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. Child-Lock The Child-Lock system has been developed to prevent children from pressing any button (except Power button) to change the programme during operation. Low noise speed control system By sensing the amount of load and balance, this system automatically distributes load evenly to minimize the spinning noise level. Auto Restart Auto Restart allows the program to restart all by itself in case of power failure. [. . . ] The water temperature [60 C 95 C Cold 30 C 40 C] can be selected in Cotton. 95 C is selected for Cotton and Baby Care. Child - lock NOTE If the Program lamps are blinked at the same time after the power off or the end of the washing, the child lock mode is set. Cancel the child lock mode by pressing the [Temp. ] and the [ Option] button simultaneously for 3 seconds. Child Lock system can be set and canceled by pressing both [Temp. ] and [Option] button simultaneously for 3 seconds. Once Child Lock is set, all buttons are not functioning except power button. Child Lock system can be set anytime even during Power-off and operation. It is automatically cancelled when an operational error occurs. 10 Start/Pause button Use the button to start or pause wash cycle. The power turn off automatically 4 minutes after the pause button is pressed. Wash program selector 8 programs can be set depending on the type of the laundry. By turing the dial (pressing the button : WD-10490S/N/T, WD-80490S/N/T ) [Cotton Baby Care Synthetic Delicate Hand Wash/Wool Quick 30 Rinse+Spin Spin] can be selected. Power button Press the button to turn on and off. Time Time Save By selecting the Time Save option, the wash time may be reduced, depending on the program selected.

When the button is pressed, [ ] is displayed, maximum delay of [ ] hours can be set. Each press advances time delay by the hour. Use [Power] button to cancel [Time Delay] [Time Delay] means the time required from the present to the completion of washing. 11 6. When much suds are sensed, the suds removing fuction such as drain, water input, and pause will operate without rotating the drum. No effect of softener Is softener put in the correct compartment of drawer? YES Compartment for softener Is the drawer closed during wash? YES Is the softener cap clogged? YES Explain how to use softener Clean the compartment for softener Visit to check 17 8-2. FAULT DIAGNOSIS AND TROUBLESHOOTING CAUTION 1. Be careful of electric shock or disconnecting the parts while troubleshooting. First of all, check the connection of each part terminal with wiring diagram. 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 YES When measuring the voltage of pin of the PWB assy, is the voltage AC 22012 NO 240V? Check the harness Assembly. PWB ASSEMBLY YES Replace PWB assembly. ALL BUTTONS ARE LOCKED EXCEPTOR FOR POWER BUTTON Does the Child-Lock is set? YES Cancle the Child-Lock by pressing [Temp. ] and [Option] Buttons simultaneously for 3 seconds. NO First, unplug the power cord and plug again. Check the buttons are working. YES Normal NO Visit to check 18 NO WATER SUPPLY Is the water supply shut-off? NO Is the tap opened? NO YES Open the tap. Is the inlet valve filter clogged with impurity? YES Clean the filter. NO option (HOT) Is resistance of the inlet valve connector between the 2 to 8 k? NO Replace the inlet valve. YES Check the voltage between each terminals of inlet Valve is 220 - 240V~. (Refer to 7-2 TEST MODE) NO Replace PWB assembly DETERGENT DOES NOT FLOW IN Refer to solution NO INLET option (HOT) Is water supplied? NO YES Wiring diagram Are receptacles correctly connected to the terminals of inlet valve? NO Check the wiring on the dispenser. Put the detergent in the correct position YES Is detergent put in the correct compartment of NO the drawer? max MAX PRE+MAIN YES MAIN WASH PRE WASH MAIN WASH : Detergent Clean the drawer. Is the detergent caked or hardened? YES SOFTENER 19 SOFTENER DOES NOT FLOW IN option (HOT) Is water supplied? NO YES Refer to NO WATER SUPPLY Check the wiring on the dispenser. Are receptacles correctly connected to the terminals of inlet valve? Wiring diagram NO YES max Is softener put in the correct compartment of drawer? NO Put it in the correct compartment. MAX YES Is the softner cap clogged? YES Clean the cap and drawer. ABNORMAL SOUND Is the pulley bolt loosened? YES Fix the bolt tightly. NO Replace the V-belt (4400FR3116B) Is the belt worn? YES NO Is there friction noise from the motor? YES Replace the motor. 20 HEATING WITHOUT WATER When pressing [Spin] and [Temp. ] at the same time after draining, is the water level frequency 252 or more?When pressing [Spin] [Temp. ] buttons at the NO same time while wash, is the water level frequency between 230 - 245V~? Replace the sensor (pressure). YES Checking voltage between two pins as press the power button is the voltage 220-240V~?Replace the PWB Assembly. NO PWB ASSEMBLY DRAIN MALFUNCTIONING Is the drain hose twisted or frozen? YES Repair drain hose NO Is the impeller of the drain pump clogged? YES Remove foreign material. NO Is the connector disconnected, disassembled? YES Reconnect or repair the connector NO Is the coil of drain pump cut-off?(resistance of coil is 90~160) YES Replace the pump assembly NO 12 When checking voltage between connectors ( , )on spinning, is the voltage 220 - 240V~ as the figure? PWB ASSEMBLY NO Replace the PWB 21 AC 220-240V HEATING CONTINUOUSLY ABOVE THE SETTING WATER TEMPERATURE (1) When disconnecting the connector (1) on the PWB assembly (Main) is the resistance of the Natural connectors [ (Blue White), (White)] between 2. 5k to 180k(105°C~0°C)? 1 6 Replace the thermistor When checking thermistor on the tub, is the thermistor loosened above 2mm from the rubber? Push the thermistor tightly to the rubber. 22 SPIN TROUBLE While spinning, is the frequency of the water level 248 or more. The frequency can be checked by pressing the [Spin] and [Temp. ] buttons at the same time on the program. Check the sensor (Pressure) or hose (Sensor). [. . . ] Do not use the pulled - out hinge again. It may be taken off during operation. (DAMPER) Clean the drain pump filter 001 3 2 1 3 2 Open the lower cover cap ( ) by using a coin. Turn the drain plug ( ) to pull out the hose. Unplug the drain plug ( ) , then the water flows out, At this time use a vessel To prevent water from flowing on the floor. If the water does not flow any more, turn the pump filter ( ) open to the left. Take out any foreign material from the pump filter ( ). [. . . ]
