The present disclosure relates to a method of controlling a dishwasher. The method of controlling a dishwasher of the present disclosure includes steps of: detecting a temperature of air supplied to a tub through a heating duct by a temperature sensor; operating a supply fan which supplies outdoor air to the heating duct; operating a heater disposed in the heating duct; determining whether the supply fan and the heater are normally operating; and determining that the supply fan and the heater are normally operating, when a temperature change detected by the temperature sensor is within a first set range.

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 conveyor warewasher includes at least one washing zone, at least one rinsing zone and a conveyor apparatus. A camera system is configured in order to capture at least one image of an portion of the conveyor apparatus continuously or at predetermined or determinable times and/or events. An image processing device is associated with the camera system and is configured to determine a position, orientation and/or alignment of washware items present in the at least one captured image. An evaluation device is further provided that is adapted to determine based on the determined position, orientation, and/or alignment of the washware items whether, at the time of the image capture, washware items are present in the portion of the conveyor apparatus (2) that: i) are transported incorrectly oriented by the conveyor apparatus (2); and/or ii) are transported misaligned by the conveyor apparatus.

Disclosed a controlling method of a dishwasher comprising a water supply step for supplying wash water, a preliminary washing step for injecting the wash water to one or more dishes, a main washing step for injecting the wash water mixed with washing liquid to the dishes, a rinsing step for injecting the wash water to the dishes, and a heating step for heating the wash water in one or more of the preliminary washing step, the main washing step and the rinsing step, wherein a heater sensing step for determining an operational state of a heater heating the wash water is performed in the heating step in a state where the circulation of wash water is stopped.

A method for reducing energy consumption by a medium heating device, the method comprising the step: scheduling an operation (501) of the first device (111) requiring heating of a first medium; scheduling an operation (502) of the second device (112) requiring heating of a second medium; the method being characterized in that it further comprises the steps of: sending (504), from the first device (111), information regarding its operation cycles and water parameters to the second device (112); rescheduling (505) operations of the liaised devices (111, 112) so that drain heat of the first medium is reused to heat a fresh intake of the second medium by the second device by means of a heat exchanger (160); instructing (506), the reprogrammed devices (111, 112) to start their operations according to the new schedule.

A method for the process programming of a household appliance includes the following steps: receiving a sequential program by the household appliance; checking the sequential program with respect to a predetermined device condition by the household appliance; and releasing the sequence of the sequential program in the household appliance as a function of the result of the check.

A dish treating appliance for treating dishes according to an automatic cycle of operation and including a tub at least partially defining a treating chamber, multiple sprayers emitting a liquid into the treating chamber, and a diverter valve having a rotatable valve body, which can be rotated to discrete rotational positions to selectively fluidly couple with the multiple sprayers. A rotary drive is located exteriorly of the tub and comprises a housing defining an interior with a liquid leak reservoir, a motor carried by the housing, an output shaft rotationally driven by the motor, extending through the housing and the tub, and operably coupled to the valve body, and a printed circuit board (PCB) located within the housing.

A dishwasher appliance that includes features for prevention and detection of flood events or tub overfills without sacrificing performance or efficiency of the dishwasher appliance is provided. Moreover, methods for detecting and preventing such flood events are also provided.

A dish washer effectively identifies a viscosity of a detergent stored in a detergent supply based on the number of revolutions of a roller sensed via a roller sensor and an operating time of a pump motor, thereby simplifying a structure, improving space utilization, and reducing a manufacturing cost as a separate electrode sensor or level sensor for identifying the viscosity of the detergent is eliminated.
