Patent attributes
A method of controlling a laundry treatment machine is provided in which a siphon phenomenon may be detected before performing a requested laundry treatment operation by performing an intermittent water supply operation and detecting a variation, if any, in a water level in a tub of a washing machine. Such a method may prevent was water form being discharged due to a siphon phenomenon, prevent the waste of wash water, and minimize the amount of time taken to discharge wash water and perform a washing operation. Such a method may also prevent the waste of detergent by using a water supply valve for a pre-washing operation to detect the siphon phenomenon. Such a method may also prevent a water supply failure from being mistaken as a siphon phenomenon by keeping a water supply valve open for a predefined amount of time and then detecting a variation, if any, in the water level in the tub.
