Product review (5 stars): OEM part - WOO!
Got the part, fit great. Just a bit of trouble getting it in there because I was trying to force the issue. It's much easier than you would think - if you find yourself trying to use something to hold the "spring" back as you line it up with the motor's teeth, full stop. Take a break and look at it again. It will fit in there without being forced, just make sure you are placing it into the correct slot.

For those of you worried about how to get it out, no worries, this is a very easy job, and this dishwasher is popular enough, you can go straight to YouTube and find numerous instructions for how to disassemble your dishwasher for a cheap repair. I would say, have a flathead screwdriver handy for prying the hood covering this piece off its mounting, as that piece can be suctioned down or cemented on with old food. (Yuck.)
