10) Spin extraction is not proceeded.
Where, what & how to check?
Motor
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.
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.
11) Spining is going on even though the lid is open.
Where, what & how to check?
Safety Switch
1. Check resistance between both
terminals of the safety switch with the lid
open.
Ball Pressure Sensor
1. Is placed the magnetic on the wash?
