5. Unscrew the pulsator pulley fixing bolt and remove
the pulsator pulley. (Fig.37)
6. Unscrew and remove the screws fastening the gear
case assembly at the tub(Fig.38).
After removing the spin dryer basket assembly, refer
to the figures and proceed as follows:
1. Remove the bellows assembly
1. Remove the bellows assembly
(Fig.40).
2. Remove the bellows supporter by using slip joint
pliers to the spin tub bottom
(Fig.40).
The assembly procedure is as follows:
1. Insert the bellows assembly into the bellows
1. Insert the bellows assembly into the bellows
supporter.
2. Fit them by pushing the bellows assembly and the
bellows supporter at the same time in the spin tub
bottom
(Fig.41).
3. Pass the spin shaft through the center hole of the
bellows assembly and insert it into the coupling
assembly
(Fig.41).
NOTE
1. Don't disassemble four screws fixing the
gear case
assembly.
2. Check the assembled condition of the
packing-P at
the tub hole is right when youassembled the gear
case assembly. (Fig.39)
The bellows assembly attached to the unit
cannot be removed unless it is torn off.

If water leakage occurs at the spin tub after
assembling the bellows assembly and the bellows
supporter, it is wrong. It could cause
an electrical
shock or a fire, therefore they
should be securely
assembled again.
NOTE
NOTE
• Damage to the plunger valve cover may
cause water leakage.
• When replacing the plunger valve assembly,
take care not to cause water leakage.

5. ADJUSTMENT
5-1. Door Switch Operation
When the spin dryer cover is raised 5 to 20 degrees,
adjust the door switch by bending the contact so it
turns on/off.
5-2. Brake operation
1. The brake assembly is fitted to the top of the spin
motor. The brake block is positioned to make
contact with the coupling. The brake is operated by
the brake wire assembly connected to the hinge of
the spin dryer cover.
2. When the spin dryer cover is raised 15 to 35
degrees, the brake should be operated and the
empty spin dryer basket should be stopped within 5
seconds.
a. When braking time is over 15 seconds, move the
brake strap hook to upper hole of the brake wire
plate to adjust.
b. When braking time is within 2 seconds, move the
brake strap hook to lower hole of the brake wire
plate to adjust.
6. EXAMINATION AFTER
REPAIRING
After repairing, perform the trial test and check the
following points.
(1) Measure the insulation resistance; it should be
more than 10MΩ
(2) This washing machine must be properly grounded
for safety.
(3) Check to make sure that there is no water leakage
from any of the connections.
(4) When spinning empty, the braking time should be
less than 5 seconds.
(5) Has grease adhered to contacts of electrical
parts?
