Method for operating a dishwasher appliance

摘要

A method for operating a dishwasher appliance is provided. The method includes interrupting a flow of wash fluid from a filtered volume of a sump to a spray assembly for a period of time during a wash cycle and resuming the flow of wash fluid from the filtered volume of the sump to the spray assembly after the period of time has elapsed during the wash cycle. The method can assist with limiting clogging of a filter media positioned between the filtered volume of the sump and an unfiltered position of the sump.

1. A method for operating a dishwasher appliance having a tub with a sump positioned at a bottom portion of the tub, a filter medium within the sump positioned between a filtered volume of the sump and an unfiltered volume of the sump, a spray assembly also positioned within a wash chamber of the tub, the method comprising:
operating a wash pump and a cross-flow pump of the dishwasher appliance, the wash pump urging wash fluid from the filtered volume of the sump to the spray assembly during said step of operating, the cross-flow pump urging wash fluid from the unfiltered volume of the sump to the wash chamber of the tub during said step of operating, a velocity of wash fluid in the filtered volume of the sump being less than a velocity of wash fluid in the unfiltered volume of the sump during said step of operating; deactivating the wash pump for a cycle time after said step of operating, the cross-flow pump being activated during said step of deactivating; and reactivating the wash pump after the cycle time has elapsed, the cross-flow pump being activated during said step of reactivating.
