KitchenAid Superba refrigerators have a grille on the bottom of the appliance. The grill allows air to flow from the kitchen into the compartment on the bottom of the refrigerator. The flow of air is important as it helps to cool the compressor, as well as evaporate the water contained in the refrigerator's drip pan, located behind the grille. To clean the grille or drip pan, you must first remove the grille.
Open the freezer and fresh food compartment doors as far as they will go.
Place both hands on the sides of the grille.
Push in on the top of the grille and lift up on the bottom to remove the grille.
