Abstract
A wash arm attachment includes a conduit connector having a threaded end extending through a central opening in the top wall of the dishwasher tub. An upper coupling member is threaded over the threaded end of the connector member and includes a shank portion which extends downwardly into a central opening of a wash arm so that the shank portion is enclosed within an internal spray chamber of the wash arm. A retainer stud has a plurality of cantilevered spring arms which are inserted into a tapered sleeve within the lower end of the upper coupling member so as to retain the two together and so as to permit the rotatable mounting of the spray arm within the dishwasher.
