A washing machine according to an aspect of the disclosure includes: a tub; a drum rotatably provided inside the tub; a heater configured to heat water; a circulating pump configured to circulate a part of the water stored in the tub; a water level sensor configured to sense a water level of water in the tub; and a controller configured to control the circulating pump to circulate the part of the water stored in the tub, and control revolutions per minute (rpm) of a motor of the circulating pump based on a water level of the water while the water stored in the tub circulates and the heater is driven.

A water reuse system and controller for controlling water levels, temperature, and quality in the rinse water reuse system and methods of using the same, in order to optimize water usage. More particularly, the application pertains to a controller and methods of using the controller to regulate water levels and water quality in a water reuse system. As part of detailing the controller and methods of using the same, an apparatus for a water reuse system is also provided.

A laundry washing machine having configured to receive a laundry cycle selection from a user interface; identify the cycle selection; upon receiving a normal laundry cycle selection, select a respective program comprising default instructions for: opening the valve one or more times to fill the drum to a default normal maintenance phase liquid level, and operating the drum motor during a normal maintenance phase to rotate the drum; and upon receiving a selection of the whites laundry cycle, select a respective program comprising default instructions for: opening the valve one or more times to fill the drum to a default whites maintenance phase liquid level, and operating the drum motor during a whites maintenance phase to cyclically rotate the drum. The default whites maintenance phase liquid level is equal to or less than the default normal maintenance phase liquid level. Methods of operating a laundry machine are also provided.

A laundry treating appliance includes a treating chamber provided for receiving laundry for treatment, a controller having a memory in which is stored a set of executable instructions including a set of cycles of operations. The laundry treating appliance also includes a user interface operably coupled with the controller and having a touchscreen configured to provide an input and output function for the controller.

A washing appliance comprising a liquid container, a liquid level indicator unit configured to provide data indicative of a liquid level in the liquid container, a drain conduit, and a drain pump. The washing appliance further comprises a control arrangement configured to operate the drain pump during a first time period, control the drain pump to a standstill during a second time period following the first time period, and monitor a change of the liquid level during the second time period using data from the liquid level indicator unit. Also provided are a method of detecting an operational error in a washing appliance, a computer program, a computer-readable medium, and a control arrangement for a washing appliance.

A cleaning appliance and method for operating a cleaning appliance with a rotatable, non-ribbed drum for the pre-treatment and main treatment of textiles. The method comprises a step of supplying a feed signal for feeding a cleaning liquid into a suds container until a predetermined initial fill level is reached. A saturation action causes the textiles to be pre-treated to be saturated with the cleaning liquid. The method includes reading in a fill level signal that represents a fill level of the cleaning liquid, and supplying a further feed signal for feeding the cleaning liquid into the suds container until a target fill level is reached. A motion signal causes a rocking rhythm of the drum for pre-treating the textiles to be pre-treated. After the pre-treatment, an unlocking of a drum door takes place in order to allow additional textiles to be added for a main treatment of the textiles.

A washing machine and method for operating a washing machine having a suds container for holding water, a non-ribbed drum rotatably mounted in the suds container for holding laundry, a motor for driving the drum, and an open or closed loop control device. The method allows the execution of a washing program (Wp) having a washing phase (Wa) and/or at least one rinsing phase (Sp), and includes feeding water into the suds container in a first region of the drum in at least one of these phases (Wa, Sp) up to a predetermined water level (h) that is selected such that the laundry floats in the water, and rotating the drum at a predetermined rotational speed such that water is released from a second region of the drum and falls onto the laundry.

A cleaning appliance and method for operating a cleaning appliance having a suds container and a rotatable drum, wherein the drum is arranged in the suds container, and wherein an inside of a drum casing of the drum is smooth, apart from a plurality of nubs, for causing the cleaning liquid in the drum to execute a wave motion during a cleaning process. The cleaning appliance has a feed unit and a drive. The method includes supplying a feed signal to the feed unit, wherein the feed signal causes a cleaning liquid to be fed into the suds container until a predetermined target fill level is reached. The target fill level causes the textiles to float inside the drum. The method includes supplying a motion signal to the drive when the target fill level is reached in order to cause a rotational motion of the drum.

A laundry treating appliance and a method operating a laundry treating appliance having a dye sensor configured to output a signal indicative of the amount of dye within liquid in the treating chamber, a controller having a memory in which is stored a set of executable instructions including at least one user-selectable cycle of operation, and a user interface operably coupled with the controller and providing an input and output function for the controller and provide information related to a dye release.

A method of controlling a washing machine of the present invention includes the steps of: (a) supplying detergent contained in a dispenser together with water into an inner tub; (b) operating a pump to transfer the water supplied together with the detergent to a plurality of nozzles disposed above the inner tub; and (c) further supplying water into the inner tub, operating the pump while the water is being supplied, and rotating the inner tub so that laundry contained in the inner tub adheres to an inner surface of the inner tub by centrifugal force during the operation of the pump.
