Hi there
Not sure if this will help or not, but have had problems with my diplomat this week! Found that by removing bottom panel flap (under door at front of washer) you can acces the program timer control. I simply turned mine using a pair of pliers. It'll show you whether the stop/start button is working, or if there is a problem with the programmer. By truning the green knob, you should be able to cycle the washer through it's washing process.
