         8 . The dishwasher of  claim 7 , wherein the controller is further configured to:
 based on an external humidity indicated by the received external humidity information being greater than or equal to a first humidity, increase the temperature of the washing water in the rinsing process of the washing course, and   based on the external humidity indicated by the received external humidity information being less than or equal to a second humidity lower than the first humidity, decrease the temperature of the washing water in the rinsing process of the washing course.   
     
     
         9 . The dishwasher of  claim 1 , further comprising:
 a tub; and   a drying device configured to heat air in the tub, the drying device including:
 a fan configured to circulate air in the tub, and 
 a heater configured to heat the air circulated by the fan, wherein the controller is further configured to: 
 based on the received external humidity information, change an operating time of the heater and an operating time of the fan in the drying process of the washing course. 
   
     
     
         10 . The dishwasher of  claim 9 , wherein the controller is further configured to:
 based on an external humidity indicated by the received external humidity information being greater than or equal to a first humidity, increase the operating time of the heater and increase the operating time of the fan in the drying process of the washing course, and   based on the external humidity being less than or equal to a second humidity lower than the first humidity, decrease the operating time of the heater and decrease the operating time of the fan in the drying process of the washing course.   
     
     
         11 . The dishwasher of  claim 1 , further comprising:
 a tub;   a door configured to open and close to respectively open and close an opening of the tub; and   a door operator configured to drive the door to open and close the opening of the tub,   wherein the controller is configured to:
 based on an external humidity indicated by the received external humidity information being greater than or equal to a first humidity, increase an opening time of the door and increase a number of times the door is opened in the drying process of the washing course. 
   
     
     
         12 . The dishwasher of  claim 1 , further comprising:
 a tub; and   an internal humidity sensor configured to sense an internal humidity of the tub and produce data corresponding to the sensed internal humidity,   wherein the controller is further configured to:
 based on a difference between an external humidity indicated by the received external humidity information and the produced data, perform an additional drying operation or stop a drying operation in the drying process of the washing course. 
   
     
     
         13 . A method for controlling a dishwasher including a user interface device, communication circuitry, and a controller, the method comprising:
