Condensation or steam escaping from the top of the door, causing a damp worktop.

Safety first: Allow the dishwasher to cool before touching the door area.

• Inspect upper seal: Check the top door gasket for gaps or deformation. Replace if it is not sealing evenly.
• Check vent: On models with a door vent, ensure the vent grille is not blocked and the flap can open or close freely.
• Installation depth: Verify that the dishwasher is flush with the cabinet front as per Rosières guidelines; if recessed too far, steam may escape incorrectly.
• Water temperature: Ensure inlet water is not excessively hot (above manufacturer's recommendation).
