A household appliance, such as a dishwasher, for treating an item, such as a dish, in a treating chamber according to at least one automatic cycle of operation includes multiple antennas for transmitting and receiving data with an external network. The multiple antennas can be coupled with a radio also located within the appliance.

A dishwasher includes a regeneration heater and a washing water heater that are controlled to operate simultaneously so that an operation period of the regeneration heater and an operation period of the washing water heater at least partially overlap each other, thereby heating the washing water and regenerating a moisture absorbent effectively and in a short time even in a washing course with a short washing cycle time.

The present invention relates to a dishwasher and a control method therefor, the dishwasher comprising: a tub for providing a washing space; a sump for collecting the washing water sprayed into the tub; a spraying arm having first and second channels, in each of which the washing water separately flows, and a plurality of spraying holes for discharging the washing water, which flows into each channel, in a preset direction; a supply pump including an impeller and a motor for rotating the impeller, and supplying the washing water, which is stored in the sump, to the spraying arm; a channel switching unit for selectively supplying the washing water to the first channel or the second channel according to the driving of the supply pump; and a control unit for controlling the driving of the motor, wherein a control unit controls the driving of the motor such that the washing water is selectively supplied to the first channel or the second channel, on the basis of a value of an electric current flowing into the motor.

A household appliance, such as a dishwasher, for treating an item according to at least one automatic cycle of operation includes multiple antennas for transmitting and receiving data with an external network. The multiple antennas can be coupled with a radio also located within the appliance.

A method for operating a water-conducting domestic appliance, such as a dishwasher, includes filling the water-conducting domestic appliance with a minimum amount of filling water that is circulated by a pump, and checking a water flow diverter for malfunctions and determining from an operational parameter of an electromotor that drives the pump whether the pump runs smoothly, thereby indicating whether the quantity of filling water corresponds to at least a nominal quantity of filling water. When the water flow diverter is not malfunctioning, the pump is again checked for smooth running or a refilling step is carried out to increase the minimum amount of filling water. Conversely, when the water flow diverter is malfunctioning, the check for smooth running or the refilling step are omitted.

A dishwasher may include a closure element, such as a door, a user interface on the closure element, and a controller. A data communication link having a first data connector may be coupled to the controller, and a second data connector may be coupled to the user interface. The first and second data connectors may communicatively couple when the closure element is in the closed condition to establish data communication between the controller and the user interface. The communication link may also form a power link to provide power to the user interface across an electrical link.

A method of operating a dish treating appliance includes a user interface disposed along the top edge of a door for selectively opening and closing access to a treating chamber. The user interface can be illuminated and operating the user interface can include operating a user input mode when the door is open and a status mode when the door is closed.

Provided among other things is a sampling system for determining an amount or type of contamination a narrow, elongated passageway in a medical device, said sampling system comprising: (a) a fluid supply system that supplies to said passageway a sampling liquid for flowing through said passageway and a gas for flowing through said passageway; and (b) a receiving container that receives liquid from said passageway, wherein said sampling liquid is sterile, wherein said sampling liquid is configured to allow recovery of viable pathogens from the passageway, and wherein said sampling liquid comprises an amount and selection of surfactant effective to enhance the dislodgement of Enterococcus faecalis and Pseudomonas aeruginosa bacteria from the narrow passageways.

A method of operating a dish treating appliance includes a user interface disposed along the top edge of a door for selectively opening and closing access to a treating chamber. The user interface can be illuminated and operating the user interface can include operating a user input mode when the door is open and a status mode when the door is closed.

A dishwasher for treating dishes according to at least one cycle of operation and methods for operating a dishwasher. The dishwasher may have a tub at least partially defining a treating chamber, a rotatable sprayer, a drive system operably coupled to the rotatable sprayer to effect movement of the rotatable sprayer, and a liquid recirculation system for recirculating sprayed liquid. The dishwasher may have a sump including a sensor enclosure, a first sensor element located within the sensor enclosure and configured to sense at least a portion of the rotatable sprayer, and a controller configured to receive output from the first sensor element and control the drive system and the liquid recirculation system to rotate the rotatable sprayer while selectively supplying liquid to the rotatable sprayer.
