Hi there, our valued customer! The hot water line to the dishwasher must provide water pressure between 20 and 120 psi. Installation and service must be performed by a qualified technician. -Chris
Hi there, Bigwater! Based on the official Frigidaire built‑in dishwasher installation instructions (which apply to the 24‑inch Top Control models like the one you mentioned, e.g., FDPH4316AD with 52 dB DishSense® technology) here is the required water supply line specification from the manual: The dishwasher’s hot water supply line is designed to be connected with a 3/8″ outside diameter (O.D.) copper tubing minimum, using the provided 90° elbow + ferrule + compression nut at the dishwasher inlet. Supply line size: Minimum 3/8″ outside diameter copper tubing (standard dishwasher supply line). Pressure: 20–120 psi. Temperature: 120–150 °F recommended. - Maico
