Bosch dryer takes too long to dry clothes; loads are still damp after full cycle.

Safety first: Unplug the dryer before cleaning vents or internal parts.

• Clean lint filter: Wash with warm water and mild detergent if coated.
• Check and clean venting: For vented models, clean the entire exhaust duct to the outside. Ensure the exterior flap opens freely.
• Clean condenser: On condensation/heat pump models, rinse the condenser and clean any additional filters.
• Clean moisture sensor bars: Wipe with alcohol to restore accurate sensing.

Drying times should improve once airflow and sensing are restored.
