I ordered a new Panel/Facia and bought replacement buttons just to be safe. All were pretty easy, but two things to BE CAREFUL about that are important. First, watch the videos about how to remove and replace the facia panel because if you do it improperly you will easily break the plastic tabs and be screwed. Secondly, The five-button MUST BE INSTALLED IN THE RIGHT ORDER. They are different from each other and the DW will not work if you don't notice that, they have letters that are stamped on them and on the spots they go in the panel. Because I missed that detail, I kept thinking I had gotten them in a bind somehow snapping it in place, but they were out of order.
Otherwise, if I had to do it again, it would only take me about 15 minutes.
