A dishwashing appliance may include a cabinet, a door, and a sensor assembly. The door may extend along the lateral direction between a first lateral edge and a second lateral edge. The door may be rotatably mounted to the cabinet to move about a rotation axis between an open position and a closed position. The sensor assembly may detect a rotational position of the door and include a stationary electrical contact and a movable electrical contact. The stationary electrical contact may be mounted on the cabinet at a first side or a second side. The movable electrical contact may be mounted on the door at the first lateral edge or the second lateral edge. The movable electrical contact may be in selective alignment and electrical connection with the stationary electrical contact based on the rotational position of the door.

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 controller may clean a filter by controllably-redirecting a controllably-movable sprayer to spray fluid onto the filter.

A dishwasher (100) for pot washing, comprising a detector (160) for automatically detecting what type of washing basket (140) has been placed in the dishwasher (100). This enables automatic selection of water pressure and granule control, such that more sensitive crockery and plates are not damaged. The detector can be an inductive sensor (160) that detects an indicating member (141) of the washing basket. The washing basket can comprise one or several indicating members, for enabling a more reliable detection. A method of operating such a dishwasher (100) comprises the steps of automatically detecting what type of washing basket (140) is placed in the dishwasher, and then controlling the water pressure and granule addition according to what washing basket was detected. A system comprises an above dishwasher and an above washing basket.

A retracting rack for an appliance such as a dish washing appliance. The rack may be positionable between a stowed position and a deployed position. A spring may drive the rack towards the stowed position. A locking mechanism may be used to secure the rack in one or more positions. A release mechanism and/or a reset mechanism may be used to control the retracting cycle of the rack.

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

A method of operating a dishwashing machine including determining user satisfaction with a dishwashing cycle, adjusting at least one operational parameter of the dishwashing cycle based on the user satisfaction, and incorporating the adjusted operational parameter into a subsequent dishwashing cycle.

Dishwashing appliances and methods, as provided herein, may include features or steps such as measuring a first pressure in a sump with a pressure sensor and storing the first pressure in a memory of the dishwashing appliance as a reference pressure. Dishwashing appliances and methods may further include features or steps for measuring a second pressure within the sump with the pressure sensor after measuring the first pressure, and determining that a check valve is failed when the second pressure exceeds the first pressure by at least a predetermined margin.

A food equipment device, such as a warewasher, includes a powered component, the powered component being one of a heating element or a pump or a fan, and a power line path for delivering power to the powered component. A contactor is provided for controlling power delivery to the powered component, the contactor including main power contacts connected in the power line path and auxiliary contacts that operate the same as, or opposite to, the main power contacts. A monitoring system is operatively connected to the auxiliary contacts to monitor an open or closed state of the auxiliary contacts and includes a voltage source operatively connected to one of the auxiliary contacts and an electrical sensor for detecting one of (i) a voltage condition of the other auxiliary contact or (ii) a current flow condition between the auxiliary contacts.

A dishwasher appliance equipped with leak detection features and a method of detecting leak conditions during an operation cycle of a dishwasher are provided. In one aspect, the dishwasher appliance includes a tub having a sump. A pressure sensor is mounted to the sump and is configured to monitor the sump pressure during an operation cycle. If the sump pressure falls below a pressure threshold during a circulation cycle, corrective action can be taken. For instance, a circulation pump circulating wash fluid through the tub can deactivated and a static pressure reading can be taken by the pressure sensor. The static pressure reading can be compared to a static pressure reading taken prior to the circulation cycle. In response to whether the static pressure is within a predetermined range of the static pressure reading taken prior to the circulation cycle, the circulation cycle can be recommenced or aborted.

Systems and methods for monitoring dish ware position and modifying the wash and dry cycle of a dishwasher by capturing and analyzing image data utilizing a plurality of cloud-connected cameras.
