I noticed that all the sudden it was making a loud steam noise but didnt see any visible steam. Noticed that the unit was very hot to the touch. Saw some water leaking out near the bottom, opened it up, theres water/condensation everywhere. What could it be? Thank you!

Edit: looked at it more closely and it appears to be a crack in the white plastic steam line. Any tips on how to replace it? I may just try shortening it and cutting off the cracked end and using it again.

Is this the same gear from last year?

If it is old enough and brittle enough it's probably just going to keep cracking, so you might want to source some replacement tubing to have on hand for when the temporary fix ages out....

Kitchenaid pro line espresso machine? Yep!

That definitely is a fear. As it stands, I may just have to replace it--I cant for the life of me remove the teflon tube from the little ferrule in the nut. I tried cutting it out slowly, tried pushing it out, pulling it out, drilling (!) it out, melting it off, nothing.  >:(

Can I just buy something like this from the hardware store, or must I order it specifically for this machine from somewhere? Mine appears to be teflon/silicone, but I could swear when I saw the parts diagram it was copper?

Looking at the parts diagram

http://www.partsguru.com/user/kitchenaid-espresso-artisan[1].pdf

Parts 27 and 35 are similar tubes in size, but Teflon vs copper if I read correctly.  If 35 is Teflon, if could have been replaced, or the diagram is wrong.  While the melting temperature of Teflon is about 635°F, the heat deflection temp is much lower.  Not sure what heat deflection means, but perhaps Teflon is not the answer to the steam boiler.  It isn't melting, but if repeated deflection temperatures are reached, perhaps it cracks.

The 4 and 2 in the description may be mm size and if so, you can look for replacement in malleable copper.  Fittings might be found for that size.

You might contact Pizzaman through the forum. He and his brother have done a lot with KP machines.

I am guessing it is Part 16 that OP is having trouble removing.
