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 household dishwasher includes a dishwasher cavity, a door attached pivotably to the dishwasher cavity, a door opening and closing device for automated opening and closing of the door, and a control unit designed to actuate the door opening and closing device. The control unit is designed to detect a motor current of a drive element of the door opening and closing device and to evaluate the detected motor current as to whether the door opening and closing device is functional or non-functional.

A dishwashing appliance may include a cabinet, a tub, a spray assembly, a drain pump, a turbidity sensor, and a controller. The tub may be positioned within the cabinet and defining a wash chamber for receipt of articles for washing. The spray assembly may be positioned within the wash chamber. The drain pump may be in fluid communication with the wash chamber. The turbidity sensor may be mounted within the cabinet. The controller may be in operative communication with the turbidity sensor and the drain pump. The controller may be configured to initiate a wash operation. The wash operation may include initiating a rinse cycle, obtaining an image of the wash chamber, determining calibration viability for the turbidity sensor based on the obtained image, and adjusting a calibration state of the turbidity sensor based on the determined calibration viability.

A dishwashing appliance may include a cabinet, a tub, a spray assembly, a circulation pump, a pressure sensor, and a controller. The circulation pump may be in fluid communication with a wash chamber defined by the tub. The pressure sensor may be upstream of the circulation pump. The controller may be configured to initiate a washing operation including activating the circulation pump, detecting movement of the door from a closed position, detecting return of the door to the closed position, calculating a modified time period for flood detection, determining pressure at the pressure sensor exceeds a pressure threshold following detecting return of the door to the closed position, initiating the modified time period in response to determining pressure at the pressure sensor exceeds the pressure threshold, and directing the circulation pump based on measuring the elevated pressure and expiration of the modified time period.

A server communicating with a dishwasher is disclosed. The server communicating with a dishwasher, according to an embodiment of the present invention, comprises: a communication unit for communicating with one or more dishwashers; a memory for storing learning results obtained using a plurality of failure causes and operation information corresponding to each of the plurality of failure causes; and a processor for receiving operation information of a particular dishwasher among the one or more dishwashers from the particular dishwasher, and acquiring the cause of a failure occurring in the particular dishwasher by using the operation information of the particular dishwasher and the learning results, wherein the learning results include relational parameters corresponding to the relationships between the plurality of failure causes and the operation information.

A dish washer includes a cabinet; a tub in the cabinet; a sump underneath the tub; a case brake on a side wall of the tub and connected to the sump; a water supply valve connected to an external water supply source; a filter assembly between the water supply valve and the case brake and including a plurality of flow path valves to open or close a plurality of flow paths corresponding to the plurality of flow path valves to guide water supplied from the external water supply source to the case brake; and a processor configured to open the water supply valve and one of the plurality of flow path valves at different points in time to start supplying the water and close the water supply valve and the one of the plurality of flow path valves at different points in time to stop the supplying of the water.

The invention relates to a dishwasher (110) for use in a means of transport (114) The dishwasher comprises a) at least one cleaning chamber (122) for receiving an item (112) to be cleaned, b) at least one application device (130) for applying the item (112) to be cleaned in the cleaning chamber (122) with at least one cleaning fluid (126): c) at least one washing tank (128) for receiving the at least one cleaning fluid (126), wherein the dishwasher (110) is designed to control a fill level of the washing tank (128) with the cleaning fluid (126) to a variably adjustable target level; d) at least one receiving device (186) for receiving at least one item of spatial information relating to the dishwasher (110); and e) at least one controller (166), wherein the controller (166) is programmed to determine the target level according to the spatial information.

A dishwasher minimizes the flow of wash water, being scattered in a washing stage or a rinsing stage, into an airflow guide through a discharge opening and the remaining wash water in the airflow guide, and prevents the reverse inflow of wash water having passed through the airflow guide to a dry air supply part.

A household dishwasher includes a washing container receiving a dishwasher load, a spray arm for applying washing liquor and/or fresh water to the dishwasher load, a drive system for actively driving the spray arm, and an overload protection mechanism configured to move autonomously from a coupling position, in which power is transmitted between the drive system and the spray arm, into a decoupling position, in which the power transmission between the drive system and the spray arm is interrupted, when the spray arm becomes blocked.

Dishwashing machine comprising: a controller; a spray arm assembly comprising a spray arm having one or more spray holes for spraying a washing load with water, and a pipe for delivering water to the spray arm; a pump for pumping water through the pipe and to the spray arm; the pipe being constructed and arranged to at least partially restrict flow of water from the pump to at least a part of the spray arm dependent on spray arm orientation relative to the pipe, a power consumption of the pump thereby being dependent at least in part on the spray arm orientation relative to the pipe; and the controller being configured to monitor the power consumption of the pump in order to determine rotational information of the spray arm.
