Drying performance is poor; clothes remain damp even after full drying cycle, but no error code is shown.

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

Step-by-step checks:

• Clean lint filters: Remove and clean any door or internal lint filters after every drying cycle.
• Clean condenser: If removable, wash the condenser thoroughly under running water to clear lint and scale.
• Inspect ducts: Check internal air ducts for lint build-up and clean with a brush and vacuum.
• Clean moisture sensors: Wipe the drum sensor strips with vinegar to restore accurate moisture detection.
• Test heater: If air remains cool during drying, test the dryer heater and thermostats as described in heater fault procedures.

When to call a technician: If airflow and heater are fine but drying is still poor, the control system or condenser pump may need professional diagnosis.
