A laundry treating apparatus includes a drum for receiving laundry; a motor for driving the drum; a drying unit for drying the laundry by heating the drum; and a memory for storing a control temperature table in which a control temperature according to the lapse of drying time of the laundry is recorded, wherein the drying unit operates on the basis of a control temperature table obtained by shifting the stored control temperature table at least one time.

A control method for a laundry treating apparatus comprises a first communication step of notifying a dryer of a washing course by a washing machine if the washing course is input through a washing machine interface provided to receive a control command; a course selection step of selecting any one of a plurality of drying courses set to the dryer by the dryer; and a predicted time transmission step of transmitting a sum of a washing time set to the washing course and a drying time set to the drying course to a terminal provided to perform communication with at least any one of the washing machine and the dryer through wire or wireless communication.

A controller is configured to monitor the pressure measurement of the pressure sensor and record an ambient temperature measurement in response to the pressure measurement stabilizing. Activate the pump and a timer in response to a drain cycle starting. The controller also configured to record a turbidity measurement from the turbidity sensor, a conductivity measurement from the conductivity sensor, and a temperature measurement from the temperature sensor and compare the turbidity measurement to a reference turbidity value, the conductivity measurement to a reference conductivity value, and the temperature measurement to the ambient temperature measurement. Then determine either a presence or an absence of fluid in the wash tub based at least in part on the turbidity measurement, the conductivity measurement, and the temperature measurement, and deactivate the pump in response to either the timer expiring or the determination of the absence of fluid in the wash tub.

A washing machine appliance includes a wash tub positioned within a cabinet, a wash basket rotatably mounted within the wash tub and defining a wash chamber for receiving a load of clothes, a drain pump fluidly coupled to the wash tub for selectively draining wash fluid from the wash tub, a drain hose fluidly coupled to the drain pump for draining wash fluid from the wash tub, and a controller operably coupled to the drain pump. The controller is configured to operate the drain pump until the wash fluid is drained to a target wash fluid level, determine that a predetermined amount of time has passed since stopping operation of the drain pump, and operating the drain pump after the predetermined amount of time has passed to drain an excess amount of the wash fluid from the wash tub.
