6) Pulsator doesn’t rotate normally.
Where, what, and how to check? Result of Check Possible Cause How to repair and settle
Pulsator rotates at one
direction.
1. The pulsator rotates normally at the
beginning of wash cycle, but it does
not rotate at clockwise direction
(locked) after some wash cycles
though there is motor-working sound?
2. In the case the pulsator doesn’t
rotate 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 and whether
the clutch rotates normally if there
is motor-working sound.
3. The pulsator doesn’t rotate in 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.
Clockwise
rotation locked.
Resistance
is normal.
V-belt is loose.
Clutch locked.
Motor rotates
at both
directions.
Motor doesn’t
rotate in both
directions.
Normal
resistance.
Unusual operation.
Defect of
controller or poor
contact of
connectors of
motor leads.
Loosen the belt.
Defect of the
clutch.
Loosen the belt.
The pulsator
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 lo cked
when turning it both
ways 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.
