A water-carrying household appliance includes a receiving unit for receiving at least one signal from an external device coupled to the household appliance, a number of actuators for executing a plurality of programs, and a selector unit for selecting a program from the plurality of programs as a function of the at least one signal received. The actuators are controlled by a control unit so as to execute the selected program.

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.

An auxiliary gray water supply device captures used wash water from a commercial warewashing machine for supply to a pre-rinse station without substantial modification of the commercial warewashing machine. The captured wash water and treatment agent are delivered to a pre-rinse station for pre-rinsing of dishes that will be washed within the commercial warewashing machine.

A flood detection sensor for a dishwasher appliance is provided. The flood detection sensor includes features that allow for detection of flood events or tub overfills without sacrificing performance or efficiency of the dishwasher during normal operating conditions and for secure mounting to a tub lip of the dishwasher.

A method and dishwasher utilize one or more tubular spray elements that are both rotatable about longitudinal axes thereof and discretely directable by one or more tubular spray element drives between a plurality of rotational positions about the longitudinal axes thereof. Thus, through the provision of discretely directable tubular spray elements, fluid such as wash fluid and/or pressurized air may be focused in a wash tub, in many cases providing more efficient resource usage in the dishwasher.

A method and dishwasher utilize one or more sprayers that are coupled to both a liquid supply and an air supply through a common hydraulic circuit such that both liquid and pressurized air can be supplied to the one or more sprayers.

A hydraulic control device for liquid-conducting household appliances or systems comprises:a hydraulic unit (11), having a hydraulic body (15) defining a duct (30) for the liquid, the duct (30) having an inlet (18i) and an outlet (31), the duct (30) being at least partially defined with an electrically insulating material, an electrical valve arrangement (EV, SH) on the hydraulic body (15), which is electrically switchable between a closing position and an opening position, to prevent or enable, respectively, passage of the liquid between the inlet (180 and the outlet (31) of the duct (30), a flow sensor on the hydraulic body (15). The flow sensor is a non-mechanical flow sensor comprising at least two electrical detection elements (42), prearranged for contact with the liquid that flows in the duct (30) and carried by at least one support (41), that preferably at least partly extends within, or faces the inside of, the duct (30) and/or has two opposite major faces that are substantially parallel to a direction of a flow of the liquid.

A condition warning system for an apparatus such as a pot and pan washing machine, a control system and control methods for a pot and pan washing machine are provided. The condition warning system includes a control system that monitors operational, safety or compliance parameters of an apparatus, and a light that illuminates a location below (or above) an operator's direct line of sight, and which is outside of the operator's direct line of sight. The control system and control methods include a punitive wash action lockout, an extended wash cycle time, and a deep clean wash cycle.

Provided herein are an appliance and method for washing and rinsing goods. The appliance may include a circulation pump, a sensing arrangement arranged to measure an indication of circulation pump pressure or process water flow rate through the circulation pump, and a controller arranged to control operating speed of the circulation pump. The controller may be further arranged to detect that the indicated circulation pump pressure or process water flow rate through the circulation pump is insufficient, and gradually reduce operating speed of the circulation pump until the circulation pump pressure or the process water flow rate through the circulation pump is at a sufficient operational level.

The present invention relates to a dishwasher for washing the dishes or the cooking utensils by spraying washing water and steam and a controlling method therefor. The method of controlling a dishwasher includes: a steam supply step of supplying washing water to the sump from an external water source; and a steam generation step of maintaining a water level of the washing water existing inside the washing pump at a certain water level or higher and heating the washing water.
