10) Spin extraction is not proceeded.
Where, what & how to check?
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;
Check frequency of the
Ball Pressure Sensor
(Pressure Switch), under no load,
or
Check contact defect of the safety
switch, defect of connection parts
and whether the lid is open if door
error is displayed.
Is placed the magnetic in Lid-B.
Check 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.
