Process

Explanation

A.

Intermittent
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

• 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

• 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.

Rinse water
supply

• Water supply for rinse process.

E.

Rinse

• Rinsing process.

F.

Last
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

• After ‘end’ signal is displayed, it stays for 8 seconds and power is

7-3. HOW TO CHECK THE WATER LEVEL FFREQUENCY

1. Press the SPIN SPEED and SOIL LEVEL buttons simultaneously.

Press the WASH/RINSE and DELAY WASH button simultaneously.

The digits indicate the water level frequency ( x.1 kHz ).

=  24.1 kHz

So, for example a display indicating 241: a Water level frequency of 241 x.1 kHz

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.
