A dishwasher and method utilize an imaging system to perform various diagnostic operations within the dishwasher, including one or more of level sensing, filter cleaning, wash tub rinse down, foam detection, imaging system cleaning, and remote viewing.

A cleaning method includes sensing at least one trigger, where the at least one trigger is chosen from sensing a presence of a first liquid within a wash compartment of an appliance with a liquid sensor and sensing an elapsed time from activation of a faucet of the appliance with a timer. The cleaning method also includes draining the first liquid from the wash compartment of the appliance. Additionally, the cleaning method includes rinsing the wash compartment with a second liquid. The draining of the first liquid from the wash compartment of the appliance and the rinsing of the wash compartment with a second liquid are both performed prior to initiating a wash cycle of the appliance.

Dishwashing appliances and methods, as provided herein, may include features or steps such as performing a drain cycle; detecting a pressure (P1) during an activation period of the drain cycle; comparing the pressure to a first predetermined pressure limit; comparing the pressure to a second predetermined pressure limit; determining a target fill value based on a difference between a normal fill volume and a fluid volume corresponding to P1; and initiating a fill cycle based on the target fill value.

Disclosed are a dishwasher that sprays wash water to wash dishes or cookware and a method of controlling the same. The method of controlling the dishwasher includes supplying wash water from an external water source to a sump and intermittently driving a washing pump to change the level of water around a filter, thereby removing filth from the filter.

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.

A dishwasher, comprising: a wash tub; a sprayer configured to spray fluid within the wash tub; an imaging device configured to capture images within the wash tub; and a controller coupled to the imaging device and configured to perform a remote start of a wash cycle in the dishwasher in response to receiving a remote start command from a remote device by: controlling the imaging device to capture one or more images within the wash tub; initiating communication of the captured one or more images to the remote device for viewing on the remote device; waiting to receive a confirmation from the remote device; and starting the wash cycle in response to receiving the confirmation from the remote device.

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 method for operating a dishwasher appliance includes receiving data indicating a status of hot water within a water heater appliance, receiving data indicating a status for a cycle of a dishwasher appliance, and initiating a start for the cycle of the dishwasher appliance in response to the data indicating the status of hot water within the water heater appliance indicating available hot water.

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.

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.
