Kitchen Aid DW blinking lights. Replaced several parts already from reading other posts. None of the solutions worked for my issue, which I am still trying to pinpoint. The NORMAL and CANCLE lights are flashing in unison. I do not have the TECH SHEET (anywhere to get one on line?) and I am a NOVICE at the ohm-meter/tester, but do have one, and am willing to do it myself...

I have replaced the control board (the beige one, not the green one). I have replaced the door switch (not the flat metal latch). The thermal fuse, when outside the DW is testing positive, and both of the door switches also test positive.

I suspect a stuck button, but how do I ensure this is it, before I order another 100 dollar part? thank you!
