Place the clip on the groove in the metal shaft and hold it with the pliers.
Push the new knob onto the shaft until it engages the clip, then press the knob to the "Off" position.
Unscrew and remove any other control knobs you wish to replace on the washer.
Twist a new knob onto each threaded metal shaft clockwise until tight.
