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 design rated 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 25 cm 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 than1 (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
than1M Ohm .
Note :When it is impossible to perform insulation check with a 500V insulation resi stance tester, use other
testers for inspection.
