If there is condensation inside the oven, this is normal. Condensation is normal since moisture will evaporate from the food during the cooking process. When foods with high moisture content are prepared, increased condensation will accumulate in the cooking compartment or inner pane of the door.

If there is condensation on the outside of the steam oven, the appliance ventilation system is not working or the appliance door is not sealed properly.
