• 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.

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.
