2. FEATURES & TECHNICAL EXPLANATION

2-1. FEATURES

Direct Drive System
The advanced Brushless DC motor directly drives the drum without belt and pulley.
Tilted Drum and Extra Large Door Opening
Tilted drum and extra large door opening make it possible to load and unload easily.

Water Circulation

Spray detergent solution and water onto the load repeatedly. Clothes are soaked more quickly and thoroughly during the wash cycle. Detergent suds are eliminated more easily by the water shower during rinse cycle. The water circulation system uses both water and detergent more efficiently.

RollerJets

Washing ball enhances wash performance and reduces damage to clothing. The jets spray and help tumble clothes to enhance
washing performance while maintaining fabric care.
Automatic Wash Load Detection
Automatically detects the load and optimizes the washing time.

Built-in Heater

Internal heater automatically heats the water to the optimum temperature on selected cycles.

Child Lock

The Child lock feature prevents children from pressing any buttons to change the settings during operation.
Using the RLM (Remote Laundry Monitor)
The RLM monitors status of your washer and/or dryer. You can plug the display unit into any power outlet in your home. The RLM Display Unit can be purchased separately for this washer.
2-2. NEURO FUZZY WASHING TIME OPTIMIZATION
To get the best washing performance, optimal time is determined by the water temperature, the selected washing temperature, and the size of the load.

Check if the washer is perfectly level as follows:
Check the leveling of the washer with a Level and check that the washer is stable.
Put an unbalance part (rubber) inside of drum and start QC test mode and run in high spin (Refer to section 7-2). When the machine is spinning in high speed, verify that it is stable. If you do not have the unbalance part, put 4.5 to 6.5 lbs (2 to 3 kg) of clothing. Once loaded, press power, Rinse+Spin and the start/pause button in sequence. When the machine is spinning in high speed, verify that it is stable.

Unbalance Part

If it is not stable, adjust feet accordingly. After the washer is level, tighten the lock nuts up against of the base of the washer. All lock nuts must be tightened.

Lock Nut

Higher

Adjustable feet Lower

Adjustable feet
If it still has severe vibration and noise, regulate a specific spin speed that generates excessive vibration and noise as follows: 1) Put an unbalance part (rubber) inside of the drum. 2) Start the QC test mode (Refer to section 7-2). 3) Press Delay Wash button, then is displayed.
4) Press the Spin Speed button repeatedly to select Extra High. 5) Press the Quick Cycle button, the spin speed is displayed. 6) Press the Start/Pause button. 7) Press the Beeper button repeatedly to set spin speed (600, 900, 1020, 1120 rpm) and check if there is vibration and noise. 8) If there is no vibration and noise, increase the spin speed by pressing Beeper button. 9) If there is vibration and noise, rotate the Cycle selector knob clockwise to reduce the Spin Speed (reduce by 50 and 100 rpm). In case of 600 rpm, it can not reduce the spin speed. 10) If vibration and noise are reduced, press the Quick Cycle button to store (2 beep sounds). * If you want to return to factory default spin speed setting, repeat above steps except step 9).
