GE Triton Dishwasher not cycling

My GE Triton dishwasher Mode GSD5900G02WW is not going through the cycles correctly. When I lock the door it starts on different cycles each time. Eample: It may start on the drying cycle first, or the rinse cycle first, or the washing cycle first. I have replaced the the module control and the push button keyboard and neither has correct the problem. Please help.
