a main body;

at least one light emitting diode (LED) disposed in an upper portion of the main body; and

a door pivotally coupled to the main body, the door having a recessed handle area formed therein to facilitate opening the door,

wherein the LED is configured to emit light in accordance with a status of the appliance, the LED is configured to project the light away from the LED such that the light appears as an area of light on the recessed handle area of the door.

17. The household appliance according to claim 16 , wherein the light is transmitted through the door.

18. The household appliance according to claim 16 , further comprising a reflector disposed on the door, wherein the reflector is configured to reflect the light onto the recessed handle area.

19. The household appliance according to claim 16 , further comprising a window disposed on the main body, wherein the light passes through the window toward the recessed handle area.
