A method of cleaning a washing machine and components and systems for enabling a user to clean the washing machine are provided. The method includes gaining access to debris that is trapped in otherwise inaccessible and/or concealed areas and/or directing debris out of inaccessible and/or concealed areas. The components include a jet channel that selectively couples to a discharge manifold in use and is removable to provide access to an interior area of the discharge manifold for cleaning. The systems include a removable mount assembly for accessories and a purging system for pumps and other concealed areas. The purging system is configured to discharge purging fluid through a plurality of purging ports and into concealed areas so as to direct debris in the concealed areas out of the concealed areas.

Dishwashing appliances and methods, as provided herein, may include features or steps such as detecting a pressure (P1) at a pressure sensor upstream from a pump while maintaining the pump in an inactive state and activating the pump from the inactive state for an activation period during which the pump remains active to motivate a continuous fluid flow. Dishwashing appliances and methods may further include features or steps for detecting a pressure (P2) at the pressure sensor upstream from the pump during the activation period and initiating a response sequence at the pump based on P1 and P2.

Dishwashing machine including an outer casing with an inner washing cavity adapted to accommodating a dishwasher rack. A catchment sink assembly is located on the bottom of the inner washing cavity to collect and accumulate liquid trickling down from the dishwasher rack momentarily located above the catchment sink assembly. The catchment sink assembly includes a basin-shaped catchment tank. A cup-shaped drain sump extends downwards from the bottom of the catchment tank and directly communicates with the inside of the catchment tank to receive washing or rinsing liquid arriving on the bottom of the catchment tank. A tubular member communicates with the catchment tank and is detachably fitted into a corresponding tubular outlet portion in the drain sump to divide the inner volume of the drain sump into a first inner-volume portion directly connected to a water drain line, and a second inner-volume portion directly connected to the suction of the pump.

A dishwasher includes a tub with an access opening to a treating chamber, a sump, at least one sprayer emitting liquid into the treating chamber, a pump, a conduit fluidly coupling the sump to the pump and the pump to the at least one sprayer, thereby defining a recirculation circuit through which the liquid sprayed into the treating chamber collects in the sump and is pumped back to the at least one sprayer. The dishwasher also includes a filter assembly in the sump for filtering the liquid in the recirculation circuit including a cleaning element.

Dishwashing appliances and methods, as provided herein, may include features or steps such as activating the drain pump for an activation period and receiving a pump-status signal during the activation period. Dishwashing appliances and methods may further include features or steps for detecting a pressure (P1) upstream from the drain pump during the activation period, determining a condition at the filter based on the pump-status signal and P1, and directing the drain pump based on the determined condition.

A method of cleaning a washing machine and components and systems for enabling a user to clean the washing machine are provided. The method includes gaining access to debris that is trapped in otherwise inaccessible and/or concealed areas and/or directing debris out of inaccessible and/or concealed areas. The components include a jet channel that selectively couples to a discharge manifold in use and is removable to provide access to an interior area of the discharge manifold for cleaning. The systems include a removable mount assembly for accessories and a purging system for pumps and other concealed areas. The purging system is configured to discharge purging fluid through a plurality of purging ports and into concealed areas so as to direct debris in the concealed areas out of the concealed areas.

A dishwasher appliance includes a filter assembly positioned between a pump and a spray body along a flow path between the pump and the spray body. The filter assembly includes a cylindrical filter medium positioned within a housing proximate an inlet of the housing. A plurality of vanes is distributed around the cylindrical filter medium. The plurality of vanes is rotatable about the cylindrical filter medium.

A sump mounting assembly for mounting a sump with the tub of a dishwasher appliance is provided herein. The sump mounting assembly may include a sump having a seal extending around the side of the sump, one or more latch receivers mounted to the bottom side of the sump, and one or more latches rotatably attached to the latch receivers, wherein rotation of the latch causes compression of the seal, thereby sealing the tub.

A water-conducting household appliance has a closable treatment chamber, in order to treat articles therein, at least one chamber water inlet into the treatment chamber, at least one sump under said treatment chamber, a coarse particle filter for separating coarse particles having a size 5 mm from water exiting from the sump, wherein the coarse particle filter has a coarse particle filter inlet, a coarse particle filter water outlet and a coarse particle filtrate outlet. According to the invention, exactly one pump having a pump inlet and a pump outlet is provided for the entire household appliance, said pump being connected downstream of the sump and the coarse particle filter water outlet. Water lines, valve devices and a discharge outlet from the household appliance are also provided, wherein a water line leads from the coarse particle filter water outlet to the pump or to the pump inlet.

A centrifugal filter unit for an apparatus, wherein the apparatus is for use in the treatment of a substrate with a treatment formulation, the centrifugal filter unit comprising; a) a housing having an outlet configured to allow a filtrate to exit the centrifugal filter unit; b) a filter rotatably mounted in the housing, wherein the filter comprises a first end proximate a first end of the housing, a second end proximate a second end of the housing and a side wall connecting the first end of the filter and the second end of the filter, wherein the first end, second end and side wall of the filter define a filter chamber, and wherein the side wall comprises perforations configured to allow liquid to pass throughout to prevent solid material from passing through; c) a lid configured to substantially seal the first end of the housing; d) an inlet configured to allow a feed to enter the filter chamber; e) a cap at the first end of the filter, wherein the cap comprises an aperture that cooperates with the inlet to allow the feed to enter the filter chamber; f) a drive means for rotating the filter; and g) an impeller, wherein the impeller is comprised in the filter chamber; wherein the centrifugal filter unit is configured such that when the impeller rotates, the feed is drawn in to the filter chamber through the inlet and liquid is expelled through the perforations.
