5-5. EXPLANATION OF EACH PROCESS
No. Process Explanation
1. Stay • Electrical power is supplied
• Washer is ready to work and the micom is in the active mode.
2. Water
supply • After loading laundry and selecting a course and a cycle, water is
supplied and drum rotates.
• When a user selects Pre-wash course, water is supplied through
pre wash valve.
3. Soaking
& washing
laundry • To get laundry wet, drum rotates clockwise and counterclockwise.
• If water amount is insufficient at this time, the Inlet valve will supply
water again.
4. Heating &
washing • The heater heats the water in drum to the selected water temperature
and drum rotates for washing.

Washing
& heating
/ washing • When the water temperature reaches to the selected temperature, the
heating stops and only the drum rotates.
• If water temperature becomes lower than selected because of
re-supplied water, the heating starts again.
7. Washing • Fuzzy Logic decides washing time according to the laundry load, water
temperature, and other factors.
8. Drainage • A pump motor drains the water from the drum.
• After sensing drained water amount by water level frequency, spin starts.
• When a heating course is selected, stay cooling process is performed to
decrease the water temperature gradually to prevent laundry from being
damaged and for safety reasons.
9. Untangling
(Sensing
eccent-
ricity) • It balances laundry load and senses the eccentricity of the load, to only
allow spinning without vibration
• If the eccentricity is worse than the allowed level, it repeats the
disentangling process. When the repeated time is more than allowed
level, it displays UE.
• If the eccentricity is good, the intermittent spin starts.
• During this process, the drain pump works for drainage intermittently.
