Caution for the safety during servicing 1. Do not allow the customer to repair the product. ☞ The person may be injured or the product life may be shortened. 2. Execute A/S after unplugging the power supply unit. ☞ Be care of the electric shock. 3. Do not plug several plugs in the same outlet. ☞ It may cause the fire due to overheat. 4. Check the damage, pressing or burning of the power plug or outlet. ☞ Replace it promptly if it has problem.(may cause the electric shock or fire) 5. Do not clean

2. Safety Devices ※ We adapt 5 safety devices for users to use this wash machine safely. 1) Balancing device (ASSY-Main PCB) → When the laundry is out of balance, to prevent the noises and vibrations, the unbalance detecting sensor helps the laundry laid even and continue the dehydating process. 2) Anti-over water supply device → Because water supply value is broken, once water is supplied to the 2/3 level of the door, the water supplied is drained automatically, Over -flow error is displayed on

Main function 6) Fuzzy washing function ( weight-sensing) ☞ After finishing initial water supply, when the fall of the water level needs supplementary water supply, Sensing function perceives the weght with the supplementary water supply numbers and starts to work. Under the course of Cotton, if the supplementary water supply numbers become 3 - 4 times the function is going at default condition ( high water level ), if 1-2 below that is going at middle level, if 0 below low water level, heati

7. General Error Function When an error occurs, this function starts to keep generating error melody sounds and displays error indicators as shown in the followings per corresponding error by blinking in 0.5sec interval until the error status is completely cleared out. In this case, all the driving devices are turned off until the error is cleared out. ○:Lighton ●:Lightoff 1.WATERSUPPLYERROR - Display shows such as fig. 1 - Water Supply Error occurs when water level frequency does not show chang
