A method for handling a clogging condition in a dishwasher may include detecting the clogging condition; upon detecting the clogging condition, interrupting a wash cycle of the dishwasher and executing a remedial operation to remove the clogging condition. The remedial operation may include executing a drain operation for a predetermined drain time during which a drain pump may be continuously or intermittently operated to drain water from a sump of the dishwasher; following the drain operation, executing a fill operation for a predetermined fill time during which a fill valve may be continuously or intermittently activated to add water to the dishwasher; and following the fill operation, executing a circulation operation during which a circulation pump may be continuously or intermittently operated to remove the clogging condition. A dishwasher and a control system for handling a clogging condition are also provided.

Provided are systems, methods, and apparatus for spraying water in a dishwasher. A dishwasher may include a wash chamber and at least one dish rack. The dishwasher may include a water inlet selectively connected to a dish spray device, which may connect a dish spray conduit with the wash chamber. The dish spray device may be oriented towards the at least one dish rack, such that the spray device may be configured to direct water onto the dishes for washing. The water inlet may be selectively connected to a fill device, which may connect the fill conduit with the wash chamber. The fill device may be configured to provide water to the circulation assembly without impinging the at least one dish rack. The one or more valves may selectively direct water from the water inlet to one or both of the dish spray device and the fill device.

A warewash machine includes in-situ tank soil load reduction that involves at least one of: (i) prior to addition of fresh water, draining the collection tank via a path that exits the collection tank at a location lower than a primary overflow path until wash liquid level in the collection tank drops below a standard operating level, and thereafter adding fresh water; or (ii) draining the collection tank via a path that exits the collection tank at a location lower than a primary overflow path while simultaneously adding fresh water; or (iii) adding fresh water such that wash liquid level in the collection tank rises above a standard operating level, and thereafter carrying out draining of the collection tank.

The present disclosure relates to an intelligent positive and negative pressure system and an operation method therefor, and an intelligent positive and negative pressure electric appliance. The system comprises a positive and negative pressure intelligent fresh-keeping refrigerator, a positive and negative pressure intelligent washing machine, a positive and negative pressure dish washing and fruit and vegetable cleaning machine, a positive and negative pressure range hood, a positive and negative pressure baking and frying microwave oven, a positive and negative pressure fresh-keeping compartment container, a positive and negative pressure fresh-keeping warehouse, a positive and negative pressure disinfection machine, and a positive and negative pressure module cabinet. By means of the positive and negative pressure system, a fluid and a carried substance thereof are regulated and controlled by means of positive and negative pressure, so as to affect an object in a specific space in a targeted manner.

Provided are systems, methods, and apparatus for spraying water in a dishwasher. A dishwasher may include a wash chamber and at least one dish rack. The dishwasher may include a water inlet selectively connected to a dish spray device, which may connect a dish spray conduit with the wash chamber. The dish spray device may be oriented towards the at least one dish rack, such that the spray device may be configured to direct water onto the dishes for washing. The water inlet may be selectively connected to a fill device, which may connect the fill conduit with the wash chamber. The fill device may be configured to provide water to the circulation assembly without impinging the at least one dish rack. The one or more valves may selectively direct water from the water inlet to one or both of the dish spray device and the fill device.

The present invention relates to a dishwasher for washing the dishes and the cooking utensils by spraying washing water, and a control method thereof. The control method of a dishwasher according to an embodiment of the present invention includes: a water supply step of opening a water supply valve to supply washing water to the sump; and a variable spray step of spraying the washing water by at least one of the plurality of spray arms by changing the number of revolutions of the washing pump stepwise, so that the washing water can be sprayed evenly.

A dishwashing appliance, including methods of operation, is provided. The dishwashing appliance may define a vertical direction and include a tub, a base conductivity sensor mounted at a first level within the tub, and an elevated conductivity sensor mounted at a second level within the tub, the second level being higher along the vertical direction than the first level.

Among other things, a method is disclosed which includes the following: acquiring at least one set of acceleration data indicative of a progression of measured acceleration values; determining status data indicative of a process step within a cleaning program performed by a dishwasher; outputting or causing the output of the determined status data. Further revealed is a device for executing and/or controlling this method, a system with one or more devices for executing and/or controlling this method and a computer program for executing and/or controlling this method by employing a processor.

A dish washer includes a cabinet, a tub positioned inside the cabinet, a sump provided in a lower portion of the tub, a case brake provided on a side wall of the tub connected to the sump, and a filter device positioned below the tub inside the cabinet, to selectively filter or unfilter water received from a water supply source, and to supply the filtered water or the unfiltered water to the case brake, the water passed through the case brake is collected in the sump, the case brake is located higher than the sump to prevent a backflow of the water collected in the sump to the case brake.
