• 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.
