Thank you for your question. You should be able to select various cycles and options. If you can not select any cycle or option and an LED light is blinking about a particular cycle then you may have a stuck or shorted keypad. This model does have a diagnostic code and it will blink out an error code. Unlike some previous models running a diagnostic test will not reset the control. To enter the diagnostic test you press any three keypads, 1,2,3,1,2,3,1,2,3 with no more than 1 second between presses. The complete/clean led will blink out any codes. There will be two numbers. The led will blink, pause 2 second the blink again. The first blink indicates the Function code while the second blink is the problem code. I hope this helps.
