Disconnect the washer from its power source before removing or replacing any components.
Open the washer door. Locate the retaining wire component around the perimeter of the door seal. Locate the tension spring portion of the retaining wire at the bottom of the door opening.
Insert needle-nose pliers or the tip of a flat-head screwdriver into the hooks at either end of the tension spring. Pull the hook to gently stretch the tension spring. Remove the retaining wire from the door seal.
Line up the replacement retaining wire with the door seal. Position the retaining wire so that the tension spring is at the bottom of the door opening. Fit the retaining wire around the top of the door seal. Stretch the tension spring. Slip the rest of the retaining wire around the bottom of the seal.
