Washer-dryer takes excessively long to dry clothes; laundry comes out damp

Safety first: Unplug the appliance before cleaning internal components.

Step-by-step checks:

• 1. Clean lint filters and condenser:
  • Remove and clean the door lint filter after every cycle.
  • Remove the condenser and rinse thoroughly under running water.
• 2. Clean moisture sensors:
  • Wipe the metal sensor bars inside the drum with a damp cloth and mild detergent or vinegar.
• 3. Check load size and type:
  • Do not overload; follow Siemens drying capacity ratings.
  • Separate heavy cottons from synthetics.
• 4. Inspect airflow:
  • Vacuum lint from ducts and around the fan and heater.

When to call a technician: If drying remains poor after cleaning, heater or sensor faults may require professional testing and replacement.
