A method, system, and computer-program product for preventing overfilling in a dishwasher are disclosed herein. According to one embodiment, a method for preventing overfilling in a dishwasher is provided, wherein the dishwasher includes a water valve for providing water to the dishwasher and a drain pump for removing water from the dishwasher. The method comprises detecting an overfill condition in the dishwasher with at least one detection device, wherein the overfill condition corresponds to a water level in the dishwasher that is greater than a predetermined threshold. The method further includes controlling the drain pump and the water valve in response to detecting the overfill condition in order to facilitate removal of the overfill condition.

A dishwasher includes in part a controllably-movable sprayer and a controller coupled to the controllably-movable sprayer and configured to control the controllably-movable sprayer to spray fluid onto one or more utensils disposed in a wash tub during a wash cycle. The controller is also configured to control the controllably-movable sprayer to spray fluid onto one or more walls of the wash tub by controllably-redirecting the controllably-movable sprayer to reorient one or more apertures of the sprayer away from the one or more utensils and towards the one or more walls.

Disclosed in the present invention are an energy-saving dishwasher and a control method therefor. The inner container is arranged inside the housing, the inner container is internally provided with a manifold type dish rack for placing dishes and spraying steam to perform steam cleaning on the dishes, and the manifold type dish rack is placed on a supporting frame fixed to the inner container. A water storage tank, a steam/hot water integrated generating device and a water pump are arranged below the inner container, and the steam/hot water integrated generating device includes a generating assembly and a control assembly. The manifold type dish rack is configured to place the dishes and simultaneously sprays steam to clean the dishes. The steam/hot water integrated generating device is configured to generate steam and hot water, heating is performed to generate the steam, and then relative cooling is performed to generate the hot water.

Systems and methods are described, which relate to internet-of-things (IoT) feedback systems, in which data received from a given IoT device may be analyzed by a controller and used as a basis for controlling another IoT device and/or sending an alert to a user. The controller may activate a dehumidifier upon detecting activation of a sump pump. The controller may monitor water level data and alert a user and/or request maintenance of the sump pump upon detecting the water level exceeds a threshold. The controller may monitor dishwasher data to detect suboptimal performance of a dishwasher, in response to which the controller may instruct valves of a manifold and water heater to close to isolate the dishwasher, and instruct a water softener to elevate salt levels of softened water during a self-cleaning cycle of the dishwasher.

A sensor module includes a housing having a first cavity and a second cavity that are in communication with each other, a liquid level sensing module mounted on the housing and sensing liquid level related information when liquid flows into the second cavity, a turbidity sensing module mounted on a section of the housing having the first cavity, and a temperature sensing module integrated with the turbidity sensing module and sensing temperature related information of the liquid when the liquid flows into the first cavity. The turbidity sensing module includes a light transmitting unit and a light receiving unit that are located on opposite sides of the first cavity to allow light emitted from the light transmitting unit to pass through the first cavity and to be received by the light receiving unit.

Disclosed herein is a dishwasher. The dishwasher includes a tub forming a washing chamber and a water tank mounted on an outer circumferential surface of the tub to communicate with the tub. The water tank includes a reservoir provided to store washing water and including a washing water outlet, a partition wall forming one side surface of the reservoir, an outside air inlet provided to maintain an internal pressure, a flow path connecting the reservoir to the outside air inlet, and an inclined rib having an inclination with respect to a water surface of the washing water in the reservoir and provided to form an air pocket.

A dishwasher appliance includes a wash tub and a sump for collecting wash fluid, a pump assembly for selectively urging a flow of the wash fluid from the sump, a pressure sensor for monitoring a wash fluid level within the wash tub, a microphone for monitoring sound generated during operation of the dishwasher appliance, and a controller configured to obtain a pressure reading using the pressure sensor, determine that the wash fluid in the sump is at a low level based at least in part on the pressure reading, energize the pump assembly to circulate the wash fluid, obtain a sound signal generated during energization of the pump assembly using the microphone, determine that the wash fluid in the sump is not at a low level based at least in part on the sound signal, and provide a user notification that the pressure sensor is defective.

A dishwasher includes a dishwasher interior for washing items to be washed with washing liquor. Arranged at a lower end of the dishwasher interior is a pump sump for collecting the washing liquor, and a sensor is arranged in the pump sump for outputting a sensor signal as a function of a presence of washing liquor at the sensor. A control apparatus configured to carry out a washing program selected from a number of washing programs is designed to determine a malfunction of a component of a hydraulic assembly as a function of the sensor signal and of a current operating state of the dishwasher.
