Alarm against breakdown: the washing machine will alarm with abnormal display and
buzzer when the drain hose is not put down, or when top lid is open, or the laundries are
slanting during automatic program or spinning, or when the imbalance can not be revised.
Automatic imbalance-revising function: during spinning, if the laundries are slanting
and bumping the tub, the washing machine will add one rinse automatically to revise the
imbalance.
10-minute quick wash program (suitable for laundries less than 2.0kg): please select
this program to wash laundries with light dirt. This program only costs 10 minutes for
