Abstract
Household appliances, such as for laundry treatment, can be configured with a sump and an outlet having a barrier for foreign objects. Foreign objects such as pocket items can inadvertently be added to the appliance along with the wash items. A barrier secured in the opening of the outlet can prevent pocket items from entering the drain.
