Dryer causes condensation or steam in the room; windows mist up heavily during use.

Safety first: Ensure the dryer is unplugged before moving it or adjusting ducting.

• Check vent hose connection: On vented models, ensure the hose is securely attached to the dryer outlet and the wall vent. Replace brittle or torn hoses.
• Clean wall vent: Remove lint and debris from the external vent grille. Ensure the flap opens freely when the dryer is running.
• Improve room ventilation: For condenser and heat pump models, ensure the room has adequate ventilation. Open a window or door slightly during operation.
• Inspect rear duct seals: Check for missing or damaged seals around the exhaust duct at the rear of the dryer. Replace seals to prevent moist air leaking into the room.
