I don't know, of course something went wrong, 40 degrees is recommended by goretex label, but honestly I don't care anymore, I gave up on goretex even before this happened since I find other materials performing far better.
Just to mention a couple: schoeller and SISP nylon-R have been treated far worst, worn almost everyday, in contact with skin, threw them at the bottom of my training bag with dirty clothes, washed and dried with any program and stay still look as new.
