Abstract
The present invention provides a wash arm assembly for a dishwasher which includes a molded plastic wash arm and a stainless steel cover. The plastic wash arm has a top surface, lateral surfaces, and a bottom surface and the stainless steel cover wraps over the top surface of the plastic wash arm, around the lateral surfaces of the plastic wash arm, and over a portion of the bottom surface of the plastic spray arm to hold the cover on the spray arm. The top surface of the plastic wash arm defines a series of wash jets and the stainless steel cover defines openings aligned with the wash jets so that the metal cover does not interfere with the wash jets.
