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.
