Motor
1. In the case that the wash motor
does not spin during spin extraction;
1) Check there is motor working
sound,or
2) If there is no motor-working
sound;
®ÁCheck frequency of the
pressure switch, under no
load, or
®ËCheck contact defect of the
safety switch, defect of
connection parts and whether
the lid is open if door error is
displayed.
®ÈCheck resistance of the motor.
Drain Motor/Clutch
1. In the case the motor rotates but the
inner tub does not rotates;
1) Check resistance of the drain
motor if the drain motor doesn't
work,or
2) Check gap between the PV link
and the brake lever if the inner
tub does not rotates while the
drain motor works.
