a steam generator configured to generate steam to be supplied to the drum, the steam generator including an electrical heater and provided in a predetermined portion of the cabinet;
a water supply source configured to:
be detachable from the laundry machine to selectively and fluidly communicate with the steam generator, and
hold water to be supplied to the steam generator;

a water supply hose configured to supply water from the water supply source to the steam generator;
a pump to pump the water of the water supply source to the steam generator;
a steam hose configured to discharge steam from the steam generator to the drum;
a switch to switch electrically the heater and the pump off when the water supply source is detached or switch electrically the heater and the pump on to enable operations of the heater and the pump when the water supply source is attached,
wherein the switch is connected between a power source and the steam generator and the switch is connected between the power source and the pump, the switch generating switching signal based on whether the water supply source is detached or not; and
a controller to receive the switching signals and sense whether the water supply source is detached or not, the controller controls an operation of the laundry machine using the switching signals.

2. The laundry machine of claim 1 , wherein the switch comprises a limit switch.

3. The laundry machine of claim 1 , wherein the water supply source comprises:
a cartridge to store water therein; and
a drawer, on which the cartridge is mounted, provided at the front of laundry machine.

a drum rotatably provided in a cabinet to receive laundry for washing or drying;
a steam generator, the steam generator including an electrical heater;
a water supply source configured to:
be detachable from the laundry machine,
hold water to be supplied to the steam generator, the water supply source separately provided from the steam generator; and
a sensor to sense whether the water supply source is detached or not;

a pump to pump the water of the water supply source to the steam generator; and
a controller to control the heater off when the sensor senses that the water supply source is detached during operation of the heater, to control the pump off when the sensor senses that the water supply source is detached during operation of the pump, and to control the heater and the pump to be operated when the sensor senses that the water supply source is attached.

7. The laundry machine of claim 6 , wherein the water supply source comprises:
a cartridge to store water therein; and
a drawer, on which the cartridge is mounted, provided at the front of laundry machine to be pulled out or pushed in.

8. The laundry machine of claim 7 , further comprising a drawer guide to guide the drawer to be pulled out or pushed in, wherein the sensor is mounted on the drawer guide and senses whether the drawer is fully pushed in.

9. The laundry dryer of claim 8 , wherein the sensor comprises at least one of a photo-sensor and a proximity-sensor.

10. The laundry machine of claim 6 , further comprising a display to indicate to a user whether the water supply source is detached or not.

11. A laundry machine comprising:
a cabinet;
a drum rotatably provided in a cabinet to receive laundry for washing or drying;
a water supply source configured to be detachable from the laundry machine, the water supply source holding water therein;
a steam generator to generate steam with water supplied from the water supply source, the steam generator including an electrical heater and provided in a predetermined portion of the cabinet separately from the water supply source;
a sensor to sense whether the water supply source is detached or not;
a pump to pump the water of the water supply source to the steam generator; and
a controller to control the heater and the pump,
wherein the controller controls the pump not to be operated when the sensor senses that the water supply source is detached or controls to be operated when the sensor senses the water supply source is attached, and
wherein the controller controls the heater and the pump off when the sensor senses that the water supply source is detached or controls the heater and the pump on when the sensor senses that the water supply source is attached.

12. The laundry machine of claim 11 , wherein the water supply source comprises:
a cartridge to store water therein; and
a drawer, on which the cartridge is mounted, provided at the front of laundry machine to be pulled out or pushed in.

13. The laundry machine of claim 12 , further comprising a drawer guide to guide the drawer to be pulled out or pushed in.

14. The laundry dryer of claim 11 , further comprising a display to indicate to a user whether the water supply source is detached or not.

15. The laundry machine of claim 11 , further comprising a switch configured to switch the heater of the steam generator off when the water supply source is detached or switch the heater on when the water supply source is attached.
