My DFD13E2X Dishwasher won't let me change settings - stuck on ECO. Have removed panel and button acts on flexible black plastic tab which should then press on a micro button on circuit board. Can't see they connect. Button movement is at 90° to micro switch movement so it won't work. The ⏯ button works fine as it acts on a switch facing outward rather than upwards. Any ideas? Is there a bit missing?
