5.ELECTRONIC COMPONENTS
Operation step Picture
1. Self-test method of wash
timer
Turn the wash timer to work
condition. Use a multimeter to
measure the connection and
disconnection condition of
input terminal(brown wire) and
output terminal (yellow or orange
wire), and the wash timer should
be regular on-off.
2. Self-test method of spin timer
Use a multimeter to test the two
conducting wire. If the spin timer
is in working condition , the two
wire should be conductive.
3. Self-test method of
wash-drain selection switch
Use a mulimeter to measure the
selection switch, the switch
should be regular on-off.
5.ELECTRONIC COMPONENTS
Operation step Picture
4. Self-test method of safety
switch
The safety switch should be in
closure state when the spin tub
cover is closed.
5. Self-test method of capacitor
Use an analog multimeter to measure
capacitance by connecting the two
ends of capacitor with the multimeter
rod connector . If the pointer swing
to the direction of smaller
resistance ,and then turn back to
the direction of “0” slowly, it means
that the capacitor is ok. If not, it
means that the capacitor is
faulted.
6. Self-test method of motor
a. To check whether the m otor
ins ulat ion is da mage d b y
wat er leak age:
Use a 500 V megohmmeter to
measure whether the insulation
resistance of motor is higher than
30MΩAt the same time, check
whether the other resistance of
the motor are normal. If the
other resistance are abnormal
(any short-circuit, open circuit
appears),the motor can not be
used. Only the two items are
normal, the motor can be used.
.
-16--15-

5.ELECTRONIC COMPONENTS
Operation step Picture
b. Check whether the motor
resistance is normal in the
condition of no water
condition:
Use a multimeter to measure the
resistance of the three leads, and
name them R1, R2, R3.Only the
“R1+R2=R3” indicates that the
motor resistance is normal.
c. Check the motor operation
condition:
For the motor under
use, add certain 20 # machine oil on
the upper and down bearing to
eliminate the negative effect arising
from water leakage.After powering
on the two components, there
should be no obvious noise,
vibration,or odor of the motor.
Use power cable with fuse to
connect the motor and capacitor
correctly, and do the preparation
for insulation.
