A domestic appliance and a method at the domestic appliance for detecting presence of process water in a pump of the domestic appliance are provided. The method of detecting process water in a pump of a domestic appliance may include operating the pump to rotate in a first direction, recording a first response of the pump rotating in the first direction based on a measured pump operation parameter, operating the pump to rotate in a second direction, and recording a second response of the pump rotating in the second direction based on the measured pump operation parameter. The method may further include comparing the first response and the second response, and determining the presence of water in the pump based on the comparison of the first and second response.

A method of operating a dishwasher includes receiving a user-input signal indicative of a hidden operating mode, selecting the hidden operating mode of a dishwasher based on the user-input signal, accessing a plurality of pre-programmed dishwashing cycles associated with the selected hidden operating mode, and operating the dishwasher in accordance with one of the plurality of pre-programmed dishwashing cycles.

Disclosed is a cleaning device for cleaning items to be cleaned. The cleaning device has at least one cleaning chamber and at least one covering device at least partially surrounding the cleaning chamber. The covering device can be moved in an opening movement direction from a closed position into an open position or in a closing movement direction from an open position into a closed position by means of at least one electromechanical drive via at least one transmission. The cleaning device furthermore has a sensor, which is designed to detect an action of a manual force on the covering device in the opening movement direction or in the closing movement direction. The cleaning device is furthermore designed to control the electromechanical drive in accordance with the detection of the action of the manual force.

A wash-aid dispenser (20) for dispensing dishwasher detergent and rinse-aid employs a DC motor (46) and drive train (43) to separately actuate a door (23) for the release of detergent and a valve (21) for the release of rinse-aid allowing reduced noise and reduce energy operation using a single electric actuator.

A removable non-integrated treating chemistry dispensing cartridge assembly may emit a signal in response to a predetermined amount of treating chemistry being detected and in response to a predetermined amount of illumination being detected.

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.

A device for rinsing a container or other kitchen utensil, the device including a rinsing pan equipped with a spray nozzle for a rinsing liquid, the spray nozzle being supplied with the rinsing liquid by a supply line that is part of the device, and the rinsing pan being provided with an outlet for discharging the rinsing liquid. The device includes a chamber which delimits an at least partially closed space above the rinsing pan, the chamber having a passage opening for introducing the container in order to rinse it, and for removing the container after rinsing.

Diverter valves and associated dishwashers with continuous calibration are provided. An example dishwasher includes a diverter valve assembly. The diverter valve assembly is configured to output a signal having a plurality of pulses. Each of the plurality of pulses has an activation time indicative of movement of the diverter valve assembly into one of a plurality of positions. The dishwasher performs operations including receiving the signal from the diverter valve assembly and determining a current activation time associated with the most recent pulse exhibited by the signal. The operations include determining a current position of the plurality of positions based at least in part on the current activation time and a plurality of average activation times respectively associated with the plurality of positions. The operations include, after determining the current position, updating the average activation time associated with the current position based at least in part on the current activation time.

Systems and methods for identifying relay contact position within an appliance. In one embodiment, an appliance includes a first motor, a second motor, and a relay. The relay can be configured to be adjusted between at least a first position associated with a first circuit of the first motor and a second position associated with a second circuit of the second motor. The appliance can also include one or more control device(s) configured to identify the position of the relay within the appliance. For instance, the control device(s) can provide a test signal to the relay and detect an output signal that is based at least in part on the input signal. The output signal can be associated with the second circuit. The control device(s) can determine whether the relay is in the first position or the second position based at least in part on the output signal.

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.
