1. Precautions
When performing trouble - shooting and part replacement during servicing note the following safety precautions.
1-1 Safety Precautions
1-1-1 Use Genuine Parts
The components of the washing machine have
safety -features such as non - combustibility and
voltage withstanding. Therefore, always use the
same part as used when replacing parts. In
particular, be sure to use only designated parts in
case of major safety parts identified by the making.
1-2 Servicing Precautions
1-2-1 Observe warnings
Be sure to follow special warnings and precautions
that are described on part labels and in the owner's
manual.
1-2-2 Special Precautions for Parts Assembly
and wiring
When assembling parts that use safety - insulation
material (such as tube and tape), or when installing
internal wiring, be sure to restore all parts and wiring
to their original positions.
Take special care to avoid contact with sharp edges.
1-2-3 Safety Checks after Servicing
After servicing, check to see that the screws, parts,
and wiring are restored to their original positions,
and check the insulation between the external
metals and the socket plug. In addition, place the
washing machine in a level position (less than 1° of
grade) to prevent vibration and noise during
operations.
1-1-2 Grounding
Connect the grounding wire to the shell plate, and
bury it under at least 25cm of earth ; alternatively,
connect the ground wire to the appropriate pin on a
properly grounded power receptacle.
Never ground it to the telephone line, lightning rod,
or gas pipe.
1-2-4 Insulation Check
Pull out the plug from the power receptacle, pour
water into the spin tub, and then set the timer.
Check to see that the insulation resistance
between the terminals of the plug and the
exposed metal is greater, than 1 M
Note : When it is impossible to perform the
insulation check with a 500V insulation
resistance tester, use other testers for
inspection.
