The Dishwasher Lower Spray Arm Nut is essential when your dishwasher's cleaning power declines. Engineered to fit an array of Frigidaire and Electrolux models, as well as certain Sears-Kenmore appliances, this original equipment manufacturer (OEM) part plays a critical role in securing the lower spray arm. With dimensions of 2.0" x 2.0" x 0.6", the nut creates a firm connection between the spray arm and the filter, enhancing stability and the machine's performance. Additionally, it mitigates the risk of leaks at the spray arm's base. Observing leaks may indicate the need for a nut replacement to maintain the dishwasher's efficiency. This component is compatible with several models from Frigidaire, Crosley, Kenmore, Tappan, and White Westinghouse.
