The WD21X10519 dishwasher flood switch and thermistor assembly helps detect excess water and provides wash-water temperature information to the dishwasher control.
Look for the number stamped or printed on the part itself. If it says WD21X10519, or any of the 3 older numbers listed under Compatible parts below, this is the replacement. Every one of them is discontinued and every one leads here.
