Open the GE dishwasher door and pull the two sliders for the upper rack out of the dishwasher, as far as they will go.
Align the dishwasher wheels with the sliders and insert the wheels into the sliders. Push the dish rack completely into the dishwasher.
Pull both sliders slightly forward so they are out of the dishwasher and you can access the ends of the sliders.
Align one of the rack stops with the end of the one of the sliders, from the inside the slider. Insert the bottom of the rack stop into the bottom channel of the slider and bend the rack stop back, toward the rear of the dishwasher. With the tab bend back, move the rack stop into the slider channel.
Install the other rack stop using the same method used to install the first.
Push the rack into the dishwasher and close the dishwasher door.
