A:Answer Hello! Yes, you would need a hot water line connection for the Dishwasher to work properly. Hot water is required for a dishwasher because the internal heating element is designed to maintain high temperatures (130 - 140 F) for cleaning and sanitizing, not to heat cold water to that temperature. Using hot water ensures detergent dissolves, cuts grease immediately, and drastically reduces energy usage compared to heating cold water.
