2. FEATURES & TECHNICAL EXPLANATION 2-1.FEATURES Jumbo drum 40% Jumbo drum can wash about 40% more per load than conventional washing machine. A bigger drum improves the wash performance. More economical by Fuzzy Logic System FUZZY Logic 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 rinse 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 or a similarly qualified person in 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....) Check the troubles referring to the troubleshooting. Decide service steps referring to disassembly instructions. Then, service and repair.
