Neff oven steam function is weak or produces no visible steam (on steam models), with no error code displayed.

Safety first: Allow the oven to cool and disconnect power before descaling.

• Check water tank: Fill the water tank with fresh water and ensure it is correctly seated.
• Run descaling program: Run the built-in descaling cycle with the recommended Neff descaler to remove limescale.
• Clean steam outlet: Gently clean the steam outlet in the cavity using a soft brush.
