4. Tighten the bolt of the coupling assembly while

adjusting it to the cutter split made in the spin
shaft(Fig. 42).

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.

•Damage to the plunger valve cover may

cause water leakage.

•When replacing the plunger valve assembly,

take care not to cause water leakage.

Apply adhesive or use hose clamps on all joints
to ensure their water tightness.
