42.FEATURES & TECHNICAL EXPLANATION2-1.Product FeaturesInverter Direct Drive system
The advanced Brushless DC motor directly drives the drum without belt and pulley.Low noise speed control system
By sensing the amount of load and balance, it evenly distributes loadto minimize the spinning noise level.Child Lock
The Child Lock prevents children from pressing any button to changethe settings during operation.More economical with Intelligent Wash system
Intelligent Wash System detects the size of load and water temperature,and then determines the optimum water level and washing time tominimize energy and water consumption.Turbo Wash
Wash the laundries in 1 hour with energy and water saving.Tag on
This is a function that may use Diagnosis, Download Course, WashingCoach, One Touch Washing, etc. when you touch the Tag On logo ofthe washing machine by using your smartphone with NFC. 6 Motion

52-2. DETERMINE WASHING TIME BY FUZZY LOGICTo get the best washing performance optimal time is determined by sensing the watertemperature, selected washing temperature and laundry amount.2-3. WATER LEVEL CONTROLThis model adopts a pressure sensor which can sense the water level in the tub.
Water supply is stopped when the water level reach the preset level, then washing program proceeds.
Spinning does not proceed until the water in the tub reduces to a certain level.watertemperaturewashing timerinse timethe bestwashingperformancespin rhythm, timelaundryamountFUZZYLOGICselectedwashingtemperatureSENSINGEFFECTPROCESSING

It may be necessary to movethemachineto a different area in the home or have the floorreinforced to properly support the operation of the unit.2. Check for humidity or any foreign objects under the feet.Clean the floor, there should be no foreign objects under the feet.If the unit has foreign objects underneath the feet, this will prevent the unit from being leveled properly and will cause vibrationsandslipping.Remove any foreign objects, if any from underneath the machine and level unit properly.See below for examples of foreign objects.1Open the box and check appliance condition.2horizontalCarpetPaperLaminatedpaperPurchasedstopper

If a cycle is started too soon after doing this, it will not help the issue.Connect the power plug to the wall outlet.Avoid connecting several electric devices, it may be the cause of a fire.about 100 cmabout 145 cmabout 105 cmLaundry tubMax. 100cmmin. 60cmMax. 100cmmin. 60cmRetainerTiestrapHose

Using the level, level the washing machine from front to back and side to side.Step 2Use the spanner wrench to adjust Legs until level and try the Diagonal test.Step 3Perform a Rinse and Spin with some clothing in the machine.To do this, put 2~3kg of clothing in the unit, turn on the unit, Select the Rinse+Spin and then start. When the unit reaches the spin cycle, watch for vibrations.If the unit is vibrating, make small adjustments to the leg until they subside. (Repeat step 2)Step 4Tightenthe lock nut against the base of the machine to locktheposition leg.Lower the foot until there is no gap between floor and foot.And only use adjustment rubberwhen difference at the leg adjustment is more than 10mm.
Place your right hand on the back, right corner and your left hand on the front,left corner of the unit, then attempt to rock the unit from corner to corner.Then, move your right hand to the front, right side and your left hand to theback, left corner and attempt to rock the unit from corner to corner.If the unit is level, it will not rock. However, if the unit is not level, it will rock.If the unit rocks, it will be necessary to adjust the leveling feet of the unit.Adjust the foot under the hand that is on the front of the machine.
