12-6. Pulsator doesn't rotate normally.
Where, what & how to check?
Pulsator rotates at one
direction.
1. In the case the pulsator doesn't
rotates either clockwise or
counterclockwise from the beginning
of wash cycle:
1) Check resistance of the wash
motor if there is no motor-working
sound.
2) Check belt tension & whether the
clutch rotates normally if there is
motor-working sound.
2. The pulsator doesn't rotate at both
directions.
1) Check whether motor rotates at
both directions if there is motor-
working sound when it's
energized.
2) Check resistance of the motor if
there is no motor-working sound.

Change the controller if
there are no contact
defects in the leads of
the motor.
Adjust belt tension by
changing motor fixing
location and change the
belt if it is impossible to
adjust belt tension.
Change the clutch if the
clutch pulley is locked
when making it rotated
clockwise and
counterclockwise by
hand.
Adjust belt tension or
change the belt if it is
impossible to adjust.
Remove cause
locking the pulsator
Change the clutch.
Change the motor if the
motor is locked when
having its shaft rotated
by hand.
Change the capacitor if
there is no contact defect
in capacitor's lead
Change the motor.
Remove the causes.
