6) Pulsator doesn't rotate normally.
Where, what & how to check?
Pulsator rotates al 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 motorworking sound
when it's energized.
2) Check resistance of the motor if there is
no motor-working sound.

Possible Cause
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.
