6) Pulsator doesn
Where, what & how to check?
Pulsator rotates at one
direction.
1. The Pulsator rotates normally at the
beginning of wash cycle, but is it not
rotate at clockwise direction (locked)
after some wash cycles though there
is motor-working sound?
2. 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.
3. 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.

Possible Cause How to repair & settle
Unusual operation.
Defect of
controller or poor
contact of
connectors of
motor leads.
Loose the belt.
Defect of the
clutch.
Loose the belt.
The plusator
locked.
Defect of the
clutch.
Defect of the
capacitor.(check
the capacitor's
capacitance)
Defect of the
motor.
Motor coil is open.
Contact defect of
the leads.

Turn the power off
and on again then that
symptom disappears.
Explain "Don't run wash
only continuously".
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.
