A method of treating at least one of laundry or dishes in a treating chamber of an appliance comprising, recirculating liquid through the treating chamber, centrifugally removing particles greater than a predetermined size from the liquid during recirculation of the liquid, and coagulating particles greater than the predetermined size in the liquid during recirculation of the liquid.

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 dishwasher and a control method thereof are disclosed. The dishwasher includes a tub accommodating an object to be washed, a spray arm rotatably provided inside the tub to spray wash water toward the object to be washed, a sump for storing wash water and collecting wash water sprayed into the tub therein, a filter separably mounted to the sump to remove foreign substances from wash water, a wash pump for supplying wash water stored in the sump to the spray arm, and a circulation passage for diverting at least a portion of the wash water supplied to the spray arm by the wash pump to the sump. After the dishes are washed, all of the wash water introduced into the wash pump is diverted into the filter. Foreign substances present in the wash water are collected in the filter and are discharged outside along with the wash water.

Disclosed is a dishwasher comprising a tub defining a washing space, a sump provided to collect the wash water injected into the tub, a supply pump provided to supply the wash water stored in the sump to the tub, a filter provided in the sump and comprising a first body having a plurality of first holes formed along a lateral circumferential surface; and a second body arranged in a radially inner side of the first body and having a plurality of second holes formed along a lateral circumferential surface, wherein the second body comprises an external wall portion in which the second holes are formed and an internal wall portion positioned in a radially inner side of the external wall and vertically extended.
