Whirlpool Dishwasher Model Guides — Complete Models Guide

Six Whirlpool dishwasher guides, and the prefix separates them: WDF520 and WDF550 are front-control machines, while WDT730, WDT750, its SAKZ variant and WDT970 are top-control. Where the console sits decides where its ribbon connector runs and how the door has to come apart, which is the first practical question behind any control complaint on these units.

Every page follows the least-expensive order: drain path and filter, wash motor, heater and thermistor at the sump, then the latch and console. These platforms share a great deal of hardware across the WDF and WDT lines, so each guide is explicit about which repair carries between them. A machine that starts only intermittently is treated as a latch and harness question long before the control board is suspected.

A dishwasher has no gas and no refrigerant, so the boundary is the junction box behind the toe kick and the door harness that flexes at every opening. Cut the circuit at the panel rather than trusting the door switch. A stainless tub weeping around the element boss is a tub finding rather than a heater finding, and it changes what the repair is.
