LG WFT15D81E(H)P Service Manual page 50

12) Spin basket doesn't reach to full speed(normal rpm)
Where, what & how to check?
Main voltage
1. Check voltage at the power outlet where
the washer is plugged into.
Starting Capacitor
1. Check the capacitance of the starting
capacitor.
Clutch Assembling
1. Check the clearance between the PV
link and the brake lever and clearance
between the clutch lever and the
adjustment bolt.
Blocked by foreign objects
1. Check whether the PV asm, the drain
pump & the drain hose are blocked by
foreign objects so that it makes water-
splashing noise in the tub.
13) Vibration, Noise or Unbalance Error happens during spin.
Where, what & how to check?
Using conditions such as installation
etc.
1. Check whether the washer is leveled.
(Check clearance with out tub and out
case the left gap is the same as the right
and the rear gap is 1.5~2 time bigger
than the front gap, between the cabinet
and the wash bowl, when it is leveled.)
2. Check whether laundry in the wash bowl
is out of balance that can cause severe
vibration & noise.
3. Check whether the pulsator doesn't
rotate during spin.(To check that,
remove the front lid and than run the
spin only cycle.)
Result of Check
Less than 85% of Tool low voltage
rating
Lack of capacitance Defect of capacitor
The clearance is less
than 2.0mm or more
than 3.5mm
Bolt clearance is out Defect of the clutch
of range 1.9 0.1mm
Result of Check
Not leveled. Defect of installation
Laundry is
unbalanced.
The pulsator rotates Defect of the clutch
initially then the inner
tub rotates.

Possible Cause
Explain the cause and
recommend using a
transfomerformer if
necessary.
Change the capacitor
Adjust PV lever bolt and paint
it red.
Reassemble the drain motor
or the clutch.
Adjust the bolt clearance.
Remove the foreign
objects.
Possible Cause
Level the washer.
Explain that it is not out of
order and it may happen
when big & long laundry is
washed.
Change the clutch spring-B
or the clutch asm.
