A method of monitoring drainage of a washing appliance such as a dishwasher or washing machine having a pump for draining a washing chamber is disclosed. The method includes receiving a time series of power consumption data relating to the operation of the washing appliance over a monitored period of operation including pumped draining of the washing chamber. A measure of the duration of a portion of the monitored period comprising said pumped draining is derived from the time series of power consumption data. The measure of duration is then compared to a reference value and an indicator of a drainage condition is determined based on the comparison. The method may be used to detect scaling or blockages in drainage flow paths.

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 washing machine appliance includes a wash basket that is rotatably mounted within a wash tub and that defines a wash chamber for receiving a load of clothes. A dispensing assembly selectively dispenses wash fluid through a discharge nozzle into the wash tub and a camera assembly is used to monitor the load of clothes and diagnose the presence of excessive bubbles after a wash cycle. Specifically, a controller of the washing machine appliance uses the camera assembly to obtain one or more images of the load of clothes after the drain phase of the wash cycle and analyzes the one or more images using a machine learning image recognition process to determine a bubble level within the wash tub. If the bubble level is greater than a predetermined bubble threshold, corrective action is taken to reduce the bubbles and detergent concentration.

A washing machine appliance includes a cabinet, a wash tub positioned within the cabinet, at least one pump in fluid communication with the wash tub, and a dual drain path connected to the at least one pump. The dual drain path may include a first drain path from the at least one pump, an unfiltered second drain path from the at least one pump in fluid parallel to the first drain path, and a water filter located along the first drain path. Some washing machine appliances may further include a controller configured to initiate a drain cycle.

A washing machine appliance includes a wash basket that is rotatably mounted within a wash tub and that defines a wash chamber for receiving a load of clothes. A dispensing assembly selectively dispenses a flow of wash fluid through a discharge nozzle into the wash tub and a camera assembly is used to monitor the wash fluid and diagnose issues related to the detergent dispenser. Specifically, a controller of the washing machine appliance uses the camera assembly to obtain one or more images of the flow of dispensed wash fluid, analyze the one or more images using a machine learning image recognition process to determine an actual detergent content of the flow of wash fluid, determine that the actual detergent content is different than a target detergent content, and implement a responsive action, e.g., such as stopping the operating cycle and notifying a user.

A water use management system may be installed in a setting that contains a primary infrastructure for water use to provide an alternate, modular infrastructure for water use. Fresh water used at various points of use, such as a shower or sink, may be diverted into the modular infrastructure prior to draining into the primary infrastructure. Once diverted, the precedent use water is received at a reservoir system where it is treated for a subsequent use. Treatment may include filtration and/or chemical treatment, and may be based upon sensor feedback from the reservoir system. Once treated, the water is ready for subsequent use and may flow from the reservoir system, via the modular infrastructure, to a subsequent point of use, such as a toilet.

Provided are a washing machine and a method for controlling the same. The method for controlling a washing machine includes supplying water to a tub, driving a driving unit to perform tumbling to rotate a drum disposed in the tub, calculating a water level variation in the tub, and displaying freeze state information on a display unit when the calculated water level variation is less than a reference water level variation.

A laundry washing machine and method control a spin operation using a spin profile determined at least in part based upon a dynamically determined load type of a load being washed in the laundry washing machine. By doing so, the speed(s) and/or amount(s) of time in which a spin operation is performed may be customized for different types of loads, and in many instances, may reduce the amount of noise and/or energy consumption associated with spinning a wash tub during a wash cycle.

A laundry washing machine and method control a time or duration of a drain operation at least in part based upon a type of a load being washed in the laundry washing machine. By doing so, the amount of time in which a drain operation is performed may be customized for different types of loads, and in many instances, may reduce the amount of noise and/or energy consumption associated with draining a wash tub during a wash cycle.

A water reuse control method of a multiple-drum washing machine, having a first washing drum and a second washing drum. When the first drum reaches a drainage process, comparing a time for the second drum to reach a water supply process T.sub.12 to a time for the first drum to reach a next drainage process T.sub.11; if T.sub.12<T.sub.11, the first drum waits until water is supplied into the second drum; if T.sub.12≧T.sub.11, water in the first drum is directly drained. Alternatively, when the first drum reaches the water supply process, comparing time for the second drum to reach the drainage process T.sub.22 to time for the first drum to reach a next water supply process T.sub.21; if T.sub.22≧T.sub.21, clean water is directly supplied into the first drum; if T.sub.22<T.sub.21, the first drum waits until the second drum drains water.
