Washer-dryer leaves clothes hot and damp after drying; condenser area very warm, and drying times are long.

Safety first: Unplug the appliance and allow it to cool before cleaning the dryer system.

Step-by-step checks:

• 1. Clean condenser: Remove the condenser (if user-removable) and rinse thoroughly to remove lint. Let it dry and refit correctly.
• 2. Clean lint filters: Clean any internal lint screens or filters after every drying cycle to maintain airflow.
• 3. Check fan and ducts: Remove the rear panel and inspect the dryer fan and ducts for lint build-up. Clean thoroughly and ensure the fan spins freely.
• 4. Installation environment: Ensure the washer-dryer has adequate space around it for air circulation and is not installed in a very confined cupboard without ventilation.
