A washing machine includes a machine housing, a tub that is suspended on a plurality of support arms in the machine housing, and a washing drum that is rotatably mounted in the tub, at least one of the support arms being equipped with a force sensor, which generates a force measurement signal that is representative of the force acting upon the respective support arm. Moreover, the washing machine is equipped with a level sensor, which generates a level signal that is representative of the water level in the washing drum, and an electronic control unit that processes the force measurement signal and the level signal, and which is configured to control the sequence of a washing program of the washing machine in dependence on the force measurement signal and the level signal.

A method of controlling a washing machine. The washing machine includes a tub configured to receive water, a drum rotatably disposed in the tub, a volute pump including (i) an impeller configured to rotate in one or more directions to pump water discharged from the tub and (ii) a pump housing that defines a volute-shaped passage configured to guide water pumped by the impeller, and a circulating water supply device configured to supply water discharged from an outlet port of the volute pump into the drum. The method includes: supplying water and detergent into the tub; and rotating the impeller of the volute pump in a first direction to discharge a first amount of water from the volute pump, the first amount of water being less than a second amount of water discharged from the volute pump based on the impeller being rotated in a second direction.

A water replenishment control method for a multi-drum washing machine. The washing machine comprises at least a first washing drum and a second washing drum. While the first washing drum is in a washing process, if the water level of washing water is lower than a set value, then a water replenishment process is executed, and before that, it is necessary to determine whether or not the second washing drum is executing a water replenishment process; if yes, the first washing drum pauses the water replenishment process, and the second washing drum executes precedence preferentially; if no, the first washing drum executes water replenishment process and terminates it when the water level of the washing water reaches a set water level.

A method for controlling a laundry treating apparatus is disclosed. The apparatus comprises a main-drum and an auxiliary-drum selectively mounted on or separated from the main-drum. The method may comprise: a main laundry quantity detection operation for detecting a laundry quantity in the main-drum via rotation of a pulsator disposed in the main-drum; and an auxiliary laundry quantity detection operation for detecting a laundry quantity in the auxiliary-drum by driving the main-drum, wherein the auxiliary laundry quantity detection operation is performed based on the main laundry quantity detected in the main laundry quantity detection operation.

A method for managing the load of washing liquid in a laundry washing machine (100) is provided. The laundry washing machine has a washing tub (110), in which washing liquid may be loaded, and a rotatable drum (115), rotatably accommodated in the washing tub (110), for containing the laundry to be washed. The method includes performing a sequence of partial loads of washing liquid into the washing tub (110). Each partial load provides for loading a corresponding liquid amount in the washing tub (110). For at least one of the partial loads in the sequence, the method provides for loading into the washing tub (110) a predetermined amount of washing liquid which depends on at least one indicative parameter related to one or more of the previous partial loads in the sequence.

Provided is a washing machine that includes a body which includes an opening, an auxiliary washing unit which forms a washing space with an open top when being mounted on the body, a water supply apparatus which supplies warm water to the washing space, and a control unit which controls distribution of cold water and hot water of the water supply apparatus to supply the warm water to the washing space.
