No. Visible condensation depends on conditions, and not every steam-assisted programme continuously fills the cavity with a dense cloud.
What the observation means
A programme may add moisture at selected stages. Opening the door to look changes its conditions and exposes you to hot vapour. The useful observations are the selected function, water messages and the food result, rather than how dramatic the steam looks.
A useful next step
Check the manual's description of the chosen programme. If it repeatedly requests water incorrectly or gives a fault, preserve that message. Do not place your face near an outlet or repeatedly open a hot door to test whether steam is emerging.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
