Dishwasher not cycling

Our dish washer will not cycle through the wash it seems to get stuck. You can turn the control knob and that doesn’t seem to make a difference. It stays on wash cycle no rinse and no dry cycle. Any ideas. Thanks Troy

Since you said you can move the timer and nothing happens it’s going to be your timer or your sump pump & motor parts are bad possibly. As your turning the knob voltage test the sump pump 120v and drain pump 120v when there in proper cycles and also amp test the heating circuit with an amp clamp you should get 6-8 AC amps…
