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 120 V at the pump when a spin cycle is selected. • Read the winding resistance of the pump motor. (14. 2 7% Ohms) • Check the pump at CN 10 (Pin 6) on PCB. It should read AC 110~120 V. (Refer to PCB Connector Check)

5. SVC Information 5 -1. Troubleshooting Problem Load is too wet at the End of the cycle. What To Do • 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”.

5. SVC Information 5 -1. Troubleshooting Problem Leaks water. What To Do • Make sure there is no leakage in the inlet hose connections. • Check for rubber gasket damage due to over-tightening. • Check standpipe for leakage. Check if the standpipe contributes the leakage. If so, the standpipe is under-capacity. In this case, make sure to seal its opening tightly. • Check waster hose connections. (Water Supply/ Drain/ Dispenser Hose & Clamp) • Check if rubber boot is water-tight. • Check for any kink on the water hoses.

5. SVC Information 5 -1. Troubleshooting Problem Excessive Suds What To Do • 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.

5. SVC Information 5 -1. Troubleshooting Problem What To Do No Key Operation • Each washing selection deactivates some buttons. • Child Lock is being activated. To exit, hold down Soil Level Key and Signal Key simultaneously until it sends out a beeping sound. • When "End“ illuminates on the display, only the Power button works.
