1. A dishwashing machine comprising:
- a washing compartment to wash tableware contained therein;
a first heater heating wash water;
a water temperature sensor sensing a temperature of the wash water;
a door opening and closing the washing compartment;
a door locking unit selectively locking the door; and
a controller controlling the door locking unit to lock the door when the temperature of the wash water sensed by the water temperature sensor is greater than a first predetermined temperature.

Abstract
A dishwashing machine provided with a controller restricting opening of a door when tableware is washed using heated wash water or dried using hot air. The controller controls a door locking unit to unlock the door when the temperature of the wash water is not greater than a first predetermined temperature. Further, the controller controls the door locking unit to unlock the door when the temperature in a washing compartment is not greater than a second predetermined temperature. The dishwashing machine allows the door to be opened only in a suitable state, providing convenient and safe use by consumers.

27. A method of controlling a dishwashing machine, comprising:
-
heating wash water;
locking a door to a washing compartment;
operating a circulating motor to circulate the wash water in the washing compartment;
determining a temperature of the wash water;
determining whether a temperature of the wash water is greater than a first predetermined temperature;
if the temperature of the wash water is greater than the first predetermined temperature, maintaining the door in a locked state and operating the circulating motor until the temperature of the wash water is not greater than the first predetermined temperature;
if the temperature of the wash water is not greater than the first predetermined temperature, unlocking the door;
determining whether a washing operation is terminated;
if the washing operation is not terminated, sensing the temperature of the wash water, operating the circulating motor, and controlling whether the door is locked based on a comparison of the temperature of the wash water to the first predetermined temperature until the washing operation is terminated;
if the washing operation is terminated, stopping the circulating motor;
heating air in the washing compartment and operating a blowing fan to circulate the air in the washing compartment;
locking the door;
sensing a temperature of the washing compartment;
determining if the temperature in the washing compartment is greater than a second predetermined temperature;
if the temperature in the washing compartment is greater than the second predetermined temperature, maintaining the door in a locked state until the temperature in the washing compartment is not greater than the second predetermined temperature;
if the temperature in the washing compartment is not greater than the second predetermined temperature, unlocking the door.
