Press and hold on/off until it beeps. Then press the program to cycle through the programs - we use the ZOOM program for usually soiled dishes. Place a dishwasher tablet (found under the sink) in the tablet drawer. If you want to set a timer press the clock button to select 3h, 6h or 9h. Then press start When the dishwasher finishes it will beep. It is recommended that you open the dishwasher at this time to help make sure the contents are dry - even just a crack.
