Turn off your washer and move it away from the wall.
Remove the screws on the rear of the top panel of the washer with your Phillips screwdriver.
Lift the top panel of the washer up to give you access to the internal tub.
Unplug the water hose connected to the port in the tub and turn the tub until you reach the area with the damaged baffle.
Pop the damaged baffle out of the housing. You may need to use the tip of a flathead screwdriver to pop it out.
Fit a new baffle in the compartment and press it in until the metal tabs lock in place.
Replace the tube and top panel of the washer.
