2. FEATURES & TECHNICAL EXPLANATION 2-1.FEATURES 40% Jumbo drum LG’s jumbo drum can wash about 40% more load than conventional washing machine. A bigger drum improves the wash performance. More economical by Intelligent Wash System Intelligent Wash 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.
2-2.DETERMINE WASHING TIME BY FUZZY LOGIC To get the best washing performance optimal time is determined by sensing of water temperature, selected washing temperature and laundry amount. water temperature washing time selected washing temperature FUZZY LOGIC rinsing time the best washing performance spin rhythm, time laundry amount SENSING PROCESSING DETERMINATION EFFECT 2-3.WATER LEVEL CONTROL This model adopts a pressure sensor which can sense the water level in the tub.
3. PARTS IDENTIFICATION Power plug If the supply cord is damaged, it must be replaced by the manufacturer or its service agents Drawer or a similarly qualified person in (For detergent and order to avoid a hazard.
4. INSTALLATION Before servicing ask the customer what the trouble is. Check the adjustment (power supply is 220-240V~, remove the transit bolts....)
