1 Precaution
When performing troubleshooting 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 suggested by the maker. In particular, be sure to use only
designated parts in case of major safety parts identified by the marker.
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 connect the wire to a
telephone line, lightning rod, or gas pipe.
§1.2 Servicing Precautions
1-2-1. Observe Warnings
Be sure to follow special warning and precautions that are described on
part labels and in the owner's manual.
1-2-2. Parts Assembly and Wiring
Be sure to use insulation material (such as tube and tape). And be sure to
restore all parts and wires to their original position. Take special care to
avoid contact with sharp edges.
1-2-3. Perform 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(one) degree) to prevent vibration and noise
during operations.
1-2-4. Insulation Checks
Pull out the plug from the power receptacle, pour water into the spin tub,
and then set the timer. Check to see
that the resistance insulation between the terminals of the plug and the
externally exposed metal is greater than 1M• .
Note :When it is impossible to perform insulation check with a 500V
insulation resistance tester, use other
testers for inspection.
