Models equipped for dual voltage can be adjusted to operate on a power supply of either 110(or 127) or 220 volts.
However, in order to avoid the danger of fire and prevent damage to the washing machine, the voltage setting
must match the voltage of your power supply. The voltage set at the factory is indicated on the "PRESENT
VOLTAGE" column in the spec. label on the back of the washing machine.
To change the voltage setting, follow the procedure that follows:

1. Unplug the power cord from the electrical outlet, by grasping the plug itself.
2. Use a screwdriver to remove the back cover from the washing machine(Fig. a).
3. Remove the polyethylene bag covering the lead wire housings(Fig. b).
4. To change the voltage setting from 220V to 110(or 127)V, disconnect the housing marked "220V" and connect

the housing marked "110 (or 127)V", to change the voltage setting from 110(or 127)V to 220V, disconnect the
housing marked “110(or 127)V” and connect the housing marked "220V"(Fig. c).

5. Cover the housings with the polyethylene bag and reattach the back cover.

6. Be sure to indicate the new voltage setting on the "PRESENT VOLTAGE" column in the spec. label for future

reference.
