Product review (4 stars): Fits Kitchenaid KUDI02IRBL1 with some modification.
It worked!  I have kitchenaid KUDI02IRBL1.  The dispenser fits but the wiring harness is different.  I removed the wax motor kit from the old dispenser and placed it on this one.  The two metal prong of this dispenser does not fit with the wiring harness of my washer.  See wax motor kits picture attached.  This one is about $20 cheaper than OEM.
