Whirlpool dishwasher parts encompass a comprehensive range of components designed to ensure efficient cleaning, water conservation, and long term reliability, tailored to meet the demands of both residential and commercial use. These parts are engineered to work in harmony, maintaining the dishwasher’s ability to remove food residues, sanitize dishes, and operate quietly. The wash module, a central component, includes the pump, motor, and spray arms. The pump, powered by a high torque motor, circulates water at pressures up to 30 psi, while the spray arms—equipped with precision nozzles—direct water to all areas of the dishwasher cavity. Replacement spray arms are designed to match the original’s hole pattern, ensuring uniform coverage, whether cleaning delicate glassware or heavily soiled pots. Water inlet valves regulate the flow of water into the dishwasher, with solenoid driven mechanisms that open and close precisely to control fill levels.
