You need to remove the front of the steamer. It has the drawbridge-like flap that folds down. The black part is held to the steamer with inner fasteners. Use a flat-head screw driver on the vertical side walls and gently pry the fasteners loose such that the front actually starts to fall inside the steamer a bit. Then remove the front and you will see what was holding everything together. I won't spoil it for you.
