The Whirlpool WPW10340745 Dishwasher Water Feed Tube Assembly directs pressurized water from the pump system to the upper spray arm, supporting water distribution across the dishwasher racks during wash cycles. Installed along the rear interior of compatible dishwashers, it connects the water supply channel to the upper spray arm assembly. The tube provides a passage for water to reach the spray arm, allowing it to distribute water over dishes and utensils. As part of the dishwasher’s circulation system, this component supports the intended water flow to the upper spray assembly.
