9.Reference Information
9-1. Troubleshooting Problem What To Do Will Not Start • Plug the unit into the wall outlet. Check for proper voltage. • Check fuse or reset circuit breaker. • Push any key to turn on the washer and press the Start/Pause key to run the washer. • Close door and push the Start/Pause key to run the washer. • Check if washer is in a pause, soak or suds process. Wait briefly and it may start. (If the washer is in suds period, Suds will light up instead of remaining time.) • Check for restricted drain system. (If there is electrical problem in drain system, “nd” error will occur after 30minutes.) • Check Water Supply. • Check the line or water valve screen filter. • Check if PCB connectors are assembled properly. • Check if CN2 terminals on PCB are in good condition. (Refer to PCB Connector Check.) • Replace PCB. Leaking • Make sure inlet hose connections are not leaking. Check for rubber gasket damage due to over tightening. • Check standpipe for leak. Wrap a dry rag around the standpipe opening. If rag becomes wet, leak is fault of home plumbing. Be sure the standpipe is capable of accepting the flow of water from the washer. • Make sure end of drain hose is correctly inserted and secured to drain standpipe. • Check internal hose connections (fill, drain systems, dispenser hoses & clamps). • Check rubber boot. Remove, reposition and reinstall, if necessary. • Check for possible kinked dispenser to outer tub hose. Hot water pressurization may force door open.

9-1. Troubleshooting Problem What To Do Will Not Spin Make sure to close the door completely. Check for water left inside the washer. If so, go to “Will Not Drain”. Perform Quick Test Mode or Quick Spin Test. Does the washer spin? (Before the test, empty the unit inside.) If it doesn’t tumble after the above, change PCB. When the problem persists, change the motor. Perform Quick Test Mode or Quick Spin Test. Does the washer spin? If it does, Check Possible unbalanced load scenario in normal mode. Check for loose connections at PCB, Water Level Sensor, Motor, Hall Sensor Wire Harness. (CN9,CN1,CN8) (Refer to the Component Testing Procedure.) Check motor windings resistance. (CN8 Pin1&3 = 11.6 ohms (at ±7% 20°C/68°F), Pin1&2 = 11.6ohms (at ±7% 20°C), Pin2&3 = 11.6 ohms (at ±7% 20°C)) No Water Fill • Perform Quick Test Mode. Check all of Water Valves visually. (Cold Water Valve, Bleach Water Valve, Softener dispenses using Cold & Bleach Water Valve, and Hot Water Valve.) • Check if water taps are turned on fully. • Check Water Valves and Water Level Sensor (Refer to PCB Connector Check) • Check if there is any kink in inlet hoses. • Check if inlet screens are clogged up. • Check if water has enough pressure. If so, find out its contributors. • Check if there is any frozen area in the unit (Drain Hose, etc) • Measure the resistance of Water Valve Coil. (It should read 1.18K ohms. Check Pin#3 of CN6 and pin# of CN4) • Check Pressure S/W and PCB for loose connections. (Refer to PCB Connector Check.)

9-1. Troubleshooting Problem What To Do Tub Full of Suds Go to “Will Not Drain” and “Will Not Spin” and check the draining. Check PCB and Drain Pump for any loose wire connection. Perform Quick Test Mode or Board Output Test to drain. Use HE (High-Efficiency) or low sudsing detergent specially formulated for front load washers. Reduce the amount of detergent for that specific load size and soil level. Keep in mind that towel creates more suds generally. Reduce the amount of detergent when water is soft, or laundry is small or lightly soiled. Do one more washing cycle with cold water and a table spoon of salt without detergent. Wet Clothes • Unbalance due to not enough load. Put additional load. • Due to excessive suds by using general detergent. Use HE (High-Efficiency) or reduce its quantity. • Low Spin Speed or Drain Only was selected. • Go to “ Will Not Spin”. Will Not Lock • Perform Quick Test Mode. Check Door Lock. Check the resistance for door lock. if Approx 0.2 ohm between the terminal of contact (white-Red wire), and if not, change pcb(refer to pcb connector check). • Read Lock Switch and PCB (CN3). (Refer to PCB Connector Check.)

9-1. Troubleshooting Problem What To Do Will Not Unlock Display shows “LO”. Turn off and on the unit. If “LO” keeps illuminating, check PCB and Door Lock Switch. Read Lock Switch and PCB (CN3). (Refer to PCB Connector Check.) Perform Quick Test Mode. Check Door Lock. Check the resistance for door unlock if Approx 0.2 ohm between the terminal of contact (white-blue wire), and if not, change pcb(refer to pcb connector check). No Key Operation • Option and Function buttons respond differently according to each cycle. • Child Lock is being activated. To exit, hold down Spin level key and soil level key simultaneously until it sends out a beeping sound. • When “End“ illuminates on the display, only Power button works. Press Power button and make new cycle selections. Will Not Drain • Check for any kink on the drain hose. If any, straight it out. • Check for any restriction in the drain hose. • Close the door and press the Start/Pause Button. For safety reasons, the washer does not tumble or spin with the door open. • When it is freezing outside, check if it is frozen inside the drain hose. • Check if the water level signal input is correct. Go to Board Input Test Mode. • Go to Quick Test Mode and do Drain Pump Test. • Check if there is any twist in the hose (the one between Tub and Drain Pump). • Check if it reads AC 120V at the pump when a spin cycle is selected. • Read the winding resistance of the pump motor. (15±10% Ohms) • Check the pump at Pin #3 of CN6 and pin #7 of CN4 on PCB. It should read AC 110~120V. (Refer to PCB Connector Check)

Wrong Water Temperature Noisy and/or Vibration/Walking
9.Reference Information 9-1. Troubleshooting Problem What To Do Wrong Water Temperature Check if both of the water taps are fully open. If the water heater is located far from the washer, screw out the hot water tap and let its water pass until you get hot water. Too Hot/Too Cold: Reduced amount of water is supplied while PCB controls the influx to regulate the actual temperature of the water in the tub. This may appear to be significantly hotter/colder than expected. Check if the temperature selection is correct. Disconnect inlet hoses from the Water Valve and remove any residue in the inlet screens. Noisy and/or Vibration/Walking • Check if the washer is leveled and the lock nuts are tightened up on the bottom plate. • Check if all of the shipping bolts and spacers are removed from the back panel. • Check if load is big enough and there is no unbalance. If there is not enough load, put in a few towels to balance it. • Check if the motor is fastened enough. • Remove various trouble contributors (such as dust coat on the floor). Buttons do not Respond • Option and Function buttons respond differently according to each cycle. • Child Lock feature has been selected. To disable feature press and hold Temp and Spin simultaneously until a beep is heard. • When display shows “End”, only the Power button will function. Press Power and make new cycle selections.

9-2. Q&A Q. The cycle is complete and “End” is displayed. How do I set another cycle? A. When “End” is displayed, the Power button should be pressed or door should be opened before selecting another cycle. The display will show “End” until washer is turned off. To turn off washer, the Power button should be pressed or the door should be opened Q. What should I do when Information Code (“dc”) lights up? A. When the Information Code is displayed, press the Start/Pause dial and then restart the cycle. For more information, refer to the Owner’s Manual Q. There is a small amount of water left in Detergent Drawer after the load is complete. Is this normal? A. It is normal for a small amount of water remaining in Detergent Drawer after it completes washing. Also, its compartment is washed again during the following rinse cycle, removing any remnants. Q. When I went back to my washer, it was turned off. What happened? A. Power button may have been accidentally bumped or pushed. Reset the cycle and start the washer. Make sure the unit is plugged into a live electrical outlet. Check house fuse or circuit breaker.
