Move the washer or
reinforce the floor.

Is the washer installed on a solidly constructed
floor?

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 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.

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. 

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 HEIGH.

5) Press the Start/Pause button.

6) Press the Beeper button repeatedly to set spin speed (600, 700, 800, 900, 1000, 1100 rpm) and check if there

is vibration and noise.

7) If there is no vibration and noise, increase the spin speed by pressing Beeper button.

8) If there is vibration and noise, press the Cycle selector button to reduce the Spin Speed (reduce by 50 and 100

rpm). In case of 600 rpm, it can not reduce the spin speed.

9) If vibration and noise are reduced, press the WASH/RINSE button to store (2 beep sounds).

* If you want to return to factory default spin speed setting, repeat above steps except step 8).
