Have not come across an IW200 model number before. If it is anything like the other IW series machines do the following. Power on at wall but off at panel. Press & hold fabric care button then push power on button on panel. Let both buttons go. On the LCD screen you will see machine size setting with three options in mm. This represents the width of the cabinet. Push the button next to the size of your cabinet. Then press power off on panel this will lock in size. Machine now ready to go.
