Process
Explanation
A.
Intermittent
spin
spin
• To reach the correct set speed, the motor rotates clockwise and
counterclockwise directions after spin process starts.
• If the water level frequency is lower than 23.0 kHz, a washer senses
suds and starts suds removal process.
B.
Rinse
spin
spin
• In this process, the remaining water during washing process is
extracted and the selected speed is kept.
• Removing suds process is in active mode at this cycle.
C.
Remaining
spin
spin
• After spin finishes, the drum rotates by remaining spin power until it stops.
Motor power is off.
• This process is overlapped with next process.
D.

drainage
drainage
• After spin finishes and power is not supplied to motor, the drum
rotates by remaining spin power
• If rinse hold is selected, the drainage is not proceeded after rinse
finishes.
G.
Disentangling
• The same as item 9.
H.
Intermittent spin • The same as item A.
I.
Main spin1
• The same as item B.
J.
Main spin2
• At the end of a main spin, the spin speed will reach the selected rpm.
K.
Remaining spin • The same with item C.
L.
Disentangling
• After spin finishes, disentangling starts to remove unbalanced
laundry.
M.
End

7-1. SAFETY CAUTION
There's built-in AC 110V and DC power in output terminal of PWB assembly in common. Be careful electric
shock when disconnecting parts while trouble shooting. (Wear Electro Static Discharge gloves when working.)
After cutting off the power when changing PWB assembly, disconnect or assemble.
Be careful static when handling PWB assembly, and use Electro Static Discharge plastic pack when delivering
or keeping it.

7-2. LOAD 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 WASH/RINSE and DELAY WASH button simultaneously.
The digits indicate the water level frequency ( x.1 kHz ).
So, for example a display indicating 241: a Water level frequency of 241 x.1 kHz
= 24.1 kHz
