Ok you need to try and reset the control board. Press "high temp scrub, energy saver dry, high temp scrub, energy saver dry, high temp scrub, energy saver dry, high temp scrub, energy saver dry"
All the lights will go solid at which point you press cancel to reset the board.
**NOTE** if you don't have a "heated dry" button, use the "air dry" or "energy saver dry" button instead.
okay its not good news, it means the main control board has failed. you will need to order and replace the board. this is located inside the door. remove all the screws around the inside of the door and lift the panel up to access this. theres a link below to order it.
