Dryer displays F20 and may not start or may stop with no heating.

Safety first: Unplug the dryer before cleaning internal components.

• Clean lint filter: Remove and wash the filter with warm water and mild detergent to remove fine residues; dry completely.
• Clean condenser (if applicable):
  • Remove the condenser from the front compartment.
  • Rinse thoroughly under running water until all lint is removed.
  • Allow to drain and dry before refitting.
• Check exhaust duct: For vented models, disconnect the exhaust hose and clear any lint or obstructions; ensure the external vent flap moves freely.
• Inspect airflow sensor: Some models use a pressure or flow sensor; ensure its tubing and wiring are intact and not blocked.
• Test: Reassemble and run a short cycle. If F20 returns despite clear airflow, the sensor or control may be faulty and require service.

Note: Regular cleaning of filters and ducts is essential to prevent overheating and fire risk.
