Method for controlling laundry treating apparatus

Abstract

Provided is a method for controlling a laundry treating apparatus. The method includes applying power to the laundry treating apparatus to input an installation inspection command through an input part, detecting an initial water level within an outer tub to store the detected initial water level value, opening a cold water valve to supply water, determining whether a water level within an outer tub reaches a target supply water level within a first set time (t1) from a time point at which the cold water valve is opened, and closing the cold water valve when the first set time (t1) elapses. When the water level within the outer tub does not reach the target supply water level within the first set time (t1), a first error message for informing a water supply error is displayed on a display part.

What is claimed is: 
     
         1 . A method for controlling a laundry treating apparatus, the method comprising:
 applying power to the laundry treating apparatus to input an installation inspection command through an input part;   detecting an initial water level within an outer tub to store the detected initial water level value;   opening a cold water valve to supply water;   determining whether a water level within an outer tub reaches a target supply water level within a first set time (t 1 ) from a time point at which the cold water valve is opened; and   closing the cold water valve when the first set time (t 1 ) elapses,   wherein, when the water level within the outer tub does not reach the target supply water level within the first set time (t 1 ), a first error message for informing a water supply error is displayed on a display part.   
     
     
         2 . The method according to  claim 1 , further comprising detecting a temperature of water for washing supplied into the outer tub to determine whether a cold water hose is normally connected to a cold water supply port. 
     
     
         3 . The method according to  claim 2 , wherein the detecting of the temperature of the water for washing is performed when at least one of three cases is satisfied,
 wherein the three cases include:   a first case in which the water level within the outer tub reaches the target supply water level within the first set time (t 1 );   a second case in which a set time elapses after displaying the first error message; and   a third case in which a signal indicating solving of the first error is inputted through an input part.   
     
     
         4 . The method according to  claim 3 , wherein, when the detected temperature of the water for washing is higher than a set temperature, a second error message is displayed on the display part, and
 the second error message is a message for informing that a hot water hose is wrongly connected to the cold water supply port of the laundry treating apparatus.   
     
     
         5 . The method according to  claim 4 , further comprising opening a hot water valve for a second set time to determine whether hot water is normally supplied. 
     
     
         6 . The method according to  claim 5 , wherein the opening of the hot water valve is performed when at least one of three cases is satisfied,
 wherein the three cases include:   a forth case in which the cold water hose is normally connected to the cold water supply port;   a fifth case in which a set time elapses after the second error message is displayed; and   a sixth case in which a signal indicating solving of the second error is inputted through the input part.   
     
     
         7 . The method according to  claim 5 , further comprising operating a jet spray for a third set time when the second set time elapses. 
     
     
         8 . The method according to  claim 7 , further comprising detecting the present water level within the outer tub and operating a drain pump when the third set time elapses,
 wherein, when the water level within the outer tub does not reach a target drain water level within a fourth set time from a time point at which the drain pump is operated, a third error message for informing a drain error is displayed on the display part.   
     
     
         9 . The method according to  claim 8 , further comprising operating a dehydration mode in which the washing motor rotates at a maximum speed for a fifth set time. 
     
     
         10 . The method according to  claim 9 , wherein the operating of the dehydration mode is performed when at least one of three cases is satisfied,
 wherein the three cases include:   a seventh case in which it is determined that the drain is properly performed;   an eighth case in which a set time elapses after the third error message is displayed; and   a ninth case in which a signal indicating solving of the third error is inputted through the input part is satisfied.
