The photos from this repair are from an Alex Duetto. For this repair you will need:
pick
flat head screw driver
2x adjustable wrench
threadlocker
Once the cap is removed use a pick to remove the e-clip from steam valve. Be careful not to fling it across the room.
At this point, you will want to apply a threadlocker to the brass bushing and fully reseat it into the knob.
