A shelf is arranged to pivot about a pivot zone. The shelf has a center of gravity offset from the pivot zone. The shelf has a first angular range about the pivot zone configured to situate a linkage in a valve activation position. The shelf has a second angular range about the pivot zone mechanically configured to situate the linkage in a valve de-activation position. An interaction portion is mechanically configured to urge the shelf from the first angular range to the second angular range by a float moving in a first direction.

A retrofit auxiliary device for distributing cleaning resources to a household cleaning appliance having a treating chamber is described wherein the device can connect to various household cleaning appliances of different makes and models and can learn the flow of water and detergent during various stages of operation and then perform the dispensing itself.

A method of operating a dishwasher having a wash tub and a reuse tank for storing liquid for subsequent reuse, wherein the condition of the water in the reuse tank may be monitored and/or acted upon to limit the likelihood of undesired effects associated with the growth of micro-organisms in the liquid.

A free-standing Energy Recovery System enables sanitary recovery of thermal energy with heat transfer from hot waste effluent to incoming domestic water. The source of the effluent may, for example, be conventional commercial ware-washing, clothes washing equipment, pasteurization and other industrial processes.

Provided herein are a dishwasher comprising a washing chamber arranged for holding soiled items to be washed, a filter, and a circulation pump, and methods of operating the same. The washing chamber may be arranged such that, when the flow of washing liquid passes through the washing chamber, soil is released from the items to be washed and caught in the flow. The filter may be such arranged that, when the flow of washing liquid with soil passes through the filter, soil is separated from the flow of washing liquid and caught at the filter. The dishwasher may further include a soil trap, which is located separate from the circulation flow, and a soil removing unit including a transport unit for transport of the soil caught at the filter into the soil trap.

A method for filling a wash tub (12) of a dishwasher (10) with water, wherein the wash tub (12) comprises a water-collecting sump pot (16) that is fixed to an opening in its bottom and said method forms part of a program cycle for the operation of the dishwasher, said method comprising the subsequent steps of: (i) opening a water inlet (13) of the dishwasher and executing a static filling of the wash tub wherein a circulation pump of the dishwasher is kept deactivated, (ii) detecting a predetermined lower water level (22) inside the sump pot (16), and (iii) starting to measure the time for the static filling when said lower water level (22) is detected.

A method of operating a dishwasher having a wash tub and a reuse tank for storing liquid for subsequent reuse, wherein the condition of the water in the reuse tank may be monitored and/or acted upon to limit the likelihood of undesired effects associated with the growth of micro-organisms in the liquid.

Method for operating a shortened dishwashing cycle of a dishwasher, dishwasher configured for running the shortened dishwashing cycle and computer program product for operating a shortened dishwashing cycle of a dishwasher. The dishwasher (10) includes a tub (12) configured to hold dishware during a dishwashing cycle, at least one circulation pump (50, 250), at least one heating element (230), and a controller (40, 240) configured to operate the dishwasher. The controller (40, 240) is configured to operate the dishwasher (10) according to at least one of a normal dishwashing cycle or the shortened dishwashing cycle. The method includes providing a first amount of warm water to the tub (12). The first amount of warm water is greater than a standard amount of water provided to the tub (12) for the normal dishwashing cycle. The method further includes, while the first amount of warm water is being provided into the tub (12), pulsing the circulation pump (50, 250) based on a predetermined timing sequence and activating the heating element (230) to heat the water within the tub (12).

An apparatus for detecting an error in the measurement of a water level in a washing machine includes a water level sensor measuring a water level in a washing tub; a water supply and drain device supplying water to the washing tub or discharging water from in the washing tub; and a control unit controlling the water supply and drain device to adjust the water level in the washing tub, and detecting a measurement error of the water level sensor based on a water level change measured by the water level sensor while the water level is adjusted.
