This was an easy $5 fix for the broken latch on the detergent door of my Kenmore dishwasher.  Searched youtube for a howto video (it seems to be a very common failure), and installed the part in about 10 minutes.  I needed a #15 torx driver to take the inner liner off the door, then a flat-bladed scewdriver to pry off the old cap.  Pay attention to which way up it goes (tab upwards on both parts) when installing the new piece.  Rotate the timer knob so the sticking-out prongs are maximally retracted before reattaching the door.  Test by turning the timer again.  Done.  No need for a new dishwasher or even an expensive service call.
