Since I've now been asked for help with this twice, I figured I should post the "rest of the story"! Here it is, cut from an email...
As it turns out, the "new" part is considered correct, but fits differently. It only uses the first screw (closest to the door opening). The other screw has to bu put back in place as well, to prevent leaks.
Problem is, even after I did this, the door closed, latched, and then WOULDN'T OPEN!!!
After playing with this for a few weeks (much to my wife's dismay :-) I decided that the new part was not angled quite right for the older door latch ... BEWARE: this may or may not be your case! These are old machines, and mine could be "worn" differently than yours!!
In any case, I took the new part and using vice-grip plier and another plier, I gently straightened the FIRST very slight "bend" in the new piece -- the slight bend FARTHEST from the latch. Instead of the very slight "dip" that was formed in the new piece, I made it ALMOST straight. Then I re-installed the part and... IT WORKED! All I had to do after that was play a bit with the position of the part so that the door closes without any "play". (Since the new part only uses one screw, and it fits in a SLOT, there is some backward/forward play...)
The part is available from Asko or Repair Clinic: http://www.repairclinic.com/SmartSearch/SSPartDetail.aspx?PartID=764296&PPStack=1
On the picture at the link... The part I straightened is right where the metal TAB starts... Just above the first black line that intersects the part at the bottom.
Good luck!! Amazing to me that Asko doesn't know this....
