I hate to be the guy who links to some other blog, but here is your service manual and was unable to find it elsewhere:tech sheet
Also, I was able to find what I believe is a part number for a replacement spring if one is needed.
I believe your front touch panel has a single screw from underneath it where the water comes out. From that point it's held in with 4 clips that are said to let loose when you pull straight back towards you. If had issues with these tabs snapping before. So, use caution and don't force it.
If you can remove the Ice funnel first, do that by pulling down on it from both sides. Again, 4 more stupid clips which are prone to break off. Maybe there are some tips from others on how to not break stuff. I carry extra funnels in various colors for just this instance. Uggg
