Product review (5 stars): This was easily replaced by my husband
Our dishwasher control panel went awry -- it got so when I pressed a button, other lights would light up.  This was easily replaced by my husband, who is quite handy.  But I would think I could have figured it out as well.  Just take out a couple screws, unplug the old one, plug in the replacement and that's about all there is to it.  It also matched our existing dishwasher part perfectly.
