Dryer display shows unusually long remaining times or constantly adjusts time upwards during drying.

Safety first: Unplug the dryer before cleaning internal components.

• Clean condenser/heat exchanger: Remove and thoroughly clean the condenser unit to restore heat transfer efficiency.
• Clean moisture sensors: Wipe the metal sensor bars inside the drum with a cloth and mild cleaner to remove residues.
• Check ambient conditions: Ensure the dryer is used in a room within the recommended temperature range; very cold rooms reduce heat pump efficiency.
• Adjust load size: Avoid overloading and ensure items are well separated to allow air circulation.
