Model number 417.44092500

Carrying a couch past the washer and whacked the knob off the beast.

Found the knob but what broke is the "program knob pin" it sits on,
Kenmore part # 134347700. Drilled a little hole in the stump and stuck
in a small screw to try to pull it out but it appears that a flange
sits behind the control console panel.

From the parts diagram/list it's not clear how I get the sucker out.
Does the whole panel need to come off to replace that pin? Is anything
holding the buttons and springs / etc in place or does it all fly out
when I take it off? Is this trivial or should I call a tech? (it's
under warranty but I don't know if that warranty includes couch
beatings)

Any advice appreciated (related to my broken washer, that is)
