Product review (5 stars): Wicked NEXXT 500 Series Gaskit replacement SKILLZ - Learn some new cuss words in 17 easy steps
Ok,  shipping was fast enough, quality of product good, and new wire/spring fasteners are included.  The remaining review is a 'how I spent my afternoon' story.

Don't try this if you get frustrated easily.  I have a BOSCH NEXXT 500 Series Washer, circa about 2009.

1) Take top off - 4 screws torx style, smaller size
2) Take hinge cover off,  4 screws torx style, smaller size
3) holding door at 90 degrees from washer pull off hinges
4) take off hinge mount, 2 screws torx style, larger size
5) take out latch screws, 2 screws torx style, smaller size
6) remove door opening surround
7) Pull off outside gasket, pulling up at wire spring
8) Pull off inside gasket, pulling up at wire spring on top where tab shows in picture
9) Fasten inner gasket.  Pull tab as shown in picture,  three holes at bottom.  Be sure to push edge in tight - as shown in picture - seem has to be tight.  This is a pain,  I worked top to bottom, both sides at a time.  I used the covered wrench handle to press on seam.  Once on it stays nice.
10) Replace new wire w/spring -- it's the larger circumference one.
11)  Cuss some, take some rest, and eat lunch.
12) Reinstall door opening surround,  attach hinge mount, latch mount, door, hinge cover
13)  Fasten outer gasket,  this is much easier than the inner one,  but wait....
14) The outer wire w/spring is very hard to fit.  Every time it pops off it pulls the gasket off
15)  I positioned the spring at the bottom.  From the top I hand fed the wire down both sides,  but stopped the right side at 3 oclock.  Once the spring was in position I held it tight with massive screw driver tip.  I held the wire with the funky pliers shown so that I could stretch the string and pull the wire about.  My third hand followed behind to keep the right side wire from pulling back out.
16) Insert miracle.  While waiting for miracle get third hand to open a beer.
17)  Test washer, get repair shop number ready.
