The present invention relates to a method of handling process water in a household appliance (1) and to a household appliance, for example a dish washer. The household appliance comprises a wash tub (3) for performing wash program cycles and a tank (5) for storing process water to be re-used in a following program cycle, the method comprising the steps of: determining (101) the type of detergent used in the household appliance with a sensor unit (7), measuring (102) the amount of detergent in the process water with the sensor unit, comparing (105) at least one sensor unit output value with a predetermined threshold value to define the quality of the process water, and storing (106) at least a part of the process water from a rinse cycle in the tank (5) when the sensor unit output value complies with the predetermined threshold value related to the quality of the process water.

A laundry treating appliance having a trating chamber and a bul dispenser and a user interface configured to provide an indication to the user related to the bulk chemistry dispenser and a controller coupled with the user interface and the bulk treating chemistry dispenser and configured to execute an operating cycle including controlling the treating chemistry meter to dispense the predetermined amount of treating chemistry and determine a number of doses of treating chemistry available in the bulk treating chemistry dispenser and method of determining the number of doses and the types of a treating chemistry available in the bulk dispensing system, and providing an indication of the determination on a user interface.

A method of determining the number of doses and the types of a treating chemistry available in the bulk dispensing system, and providing an indication of the determination on a user interface.

Disclosed herein is a chemical dosing system for an appliance, such as a laundry washing machine or a dishwashing machine, having a water inlet, the system comprising a meter for determining the volume of water supplied to the appliance, a pump for dispensing a quantity of a chemical to the appliance and a control unit arranged to receive a signal from the meter and to cause to be dispensed to the appliance a volume of chemical that is proportional to the quantity of water supplied to the appliance. The disclosed system may enable a correct quantity of chemical to be automatically dispensed to many types of appliance, without the need to know anything about the appliance, or to derive electrical signal from the appliance.

A household appliance for treating at least one item according to at least one cycle of operation includes a treating chemistry dispenser receiving a unit dose container and having a door moveable between an opened position and a closed position, a piercing mechanism located proximate to the treating chemistry dispenser and having a piercer that is moveable between a non-piercing position and a piercing position where the piercer is moved to perforate a unit dose container received within the treating chemistry dispenser.

A method for operating a laundry washing appliance having a washing chamber to wash laundry the method includes selecting a default washing temperature and/or a washing cycle having a default washing temperature; supplying a detergent to the washing chamber; and determining a type of the detergent which has been added. When the detergent is of a first type, then the method includes comparing the default washing temperature with a threshold temperature and if the default washing temperature is higher than the threshold temperature, then emitting a warning signal and/or changing said default washing temperature.

An automated cleaning machine includes a trained cleaning outcome classifier that automatically classifies or scores cleaning outcomes for a cleaning machine using machine learning techniques. The cleaning outcome classifier may be trained on training data comprising a plurality of training inputs and a known output for each of the plurality of training inputs. Each of the plurality of training inputs may include one or more cleaning process parameters corresponding to a cleaning process executed by a cleaning machine executed during a training phase. The known output for each training input may include a cleaning outcome classification or score. The cleaning outcome of a novel cleaning process may then be classified or scored with the trained cleaning outcome classifier based on one or more cleaning process parameters corresponding to the novel cleaning process.

A cleaning composition dispensing device for use in an automatic dishwasher is provided for dispensing the right cleaning composition at the right time during a wash cycle. The device includes wash cycle sensing system that controls the release of cleaning composition via temperature and water flow data measured with respect to time. The device includes a refill compartment receiving a multi-section refill including at least two cleaning composition sections divided by separable seams. The multi-section refill separates into individual cleaning composition sections during placement in the refill compartment that fall into the slots forming the refill compartment.

A method includes starting cleaning program stored in memory of control device of dishwasher by start signal triggered on input device of the dishwasher, detecting current actual value of state variable in the dishwasher by sensor, comparing the detected actual value with reference value of relevant state variable stored in the control device, determining parameter and/or parameter value associated with the parameter based on the comparison, outputting output signal associated with the parameter and/or the parameter value on output device, detecting adjustment signal associated with the output signal, generated in response to input on the input device or on input device associated with the dishwasher, and associated with the parameter and/or the parameter value, and continuing to run the cleaning program with original program configuration, modified program configuration, or suspend strategy for ending the cleaning program, according to the adjustment signal.
