2. FEATURES & TECHNICAL EXPLANATION
2-1. FEATURES
Direct Drive SystemThe advanced Brushless DC motor directly drives the drumwithout belt and pulley.
Tilted Drum and Extra Large Door Opening
The tilted drum and extra large door opening make it possibleto load and unload easily.
Water CirculationSpray 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 showerduring rinse cycle. The water circulation system uses bothwater and detergent more efficiently.
RollerJets
The washing ball enhances wash performance and reduces
damage to clothing. The jets spray and help tumble clothes to enhancewashing performance while maintaining fabric care.
Automatic Wash Load Detection
Automatically detects the load and optimizes the washing time.
Built-in Heater
The internal heater automatically heats the water to the optimumtemperature on selected cycles.
Child Lock
The Child lock feature prevents children from pressing any buttonsto change the settings during operation.

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.
2-3. WATER LEVEL CONTROL
This model incorporates a pressure sensor which can sense the water level in the tub.
The water supply is stopped when the water level reaches the preset level, the washing
program then proceeds.
Spinning does not proceed until the water in the tub drains to a certain level.
2-4. DOOR CONTROL The door can be opened by pulling the door handle whenever washer is not in operation.
When the cycle is completed, the DOOR LOCKED light will turn off.
If a power failure has occurred while in operation, the door will unlock after 5 minutes.
Clicking sounds can be heard when the door is locked/unlocked.

2-6. DOOR LOCKED LAMP LIGHTS When the frequency of water level is lower than 22.9 kHz
(It can be canceled when the frequency is more than 23.8 kHz)
When the temperature inside the tub is higher than 45 C and water level is not 25.5 kHz
(It can be canceled when the water level is 25.5 kHz or the temperature inside the tub is lower than 40 C)
2-7. CHILD LOCK Use this option to prevent unwanted use of the washer. Press and hold PRE WASH button for 3 seconds to
lock/unlock control.
When Child lock is set, CHILD LOCK lights and all buttons are disabled except the Power button. You can
lock the washer while it is operating.

7. TROUBLESHOOTING
7-1. BEFORE PERFORMING SERVICE Be careful of electric shock when disconnecting parts while troubleshooting.
The voltage of each terminal is 110V a.c and DC when the unit is plugged in.
7-2. QC TEST MODE.The washer must be empty and the controls must be in the off state.
1. Press the SPIN SPEED and SOIL LEVEL buttons simultaneously.
2. Press the Power button, while the above condition. Then buzzer will sound twice.
3. Press the Start/Pause button repeatedly to cycle through the test modes.
7-3. HOW TO CHECK THE WATER LEVEL FREQUENCY Press the Spin and Dry button simultaneously.
So, for example a display indicating 241: a Water level frequency of 241 x.1 kHz
= 24.1 kHz
The digits indicate the water level frequency ( x.1 kHz ).

Have all the transit bolts and base packingbeen removed?
Remove the transit boltsand Base packing.
Move the washer orreinforce the floor.
Is the washer installed on a solidly constructedfloor?
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.
VIBRATION & NOISE IN SPIN
If it is not stable, adjust feet accordingly. Afterthe washer is level, tighten the lock nuts up
against of the base of the washer. All lock nutsmust be tightened.
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/pausebutton in sequence.When the machine is spinning in high speed,
verify that it is stable.
7/28/2019 MFL30138908_svc

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 vibrationand 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 50and 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).
