Washer-dryer combo takes excessively long to dry clothes; loads come out damp even after full cycle.

Safety first: Unplug the unit before internal cleaning.

• Clean lint filter every load: Remove all lint from the filter before each drying cycle.
• Clean condenser: If equipped, remove and rinse the condenser as described for E12.
• Reduce load size: Dry smaller loads; overloading reduces air circulation and drying efficiency.
• Check room temperature: Ventless combos dry more slowly in very cold or very humid rooms; ensure adequate ambient conditions.
• Inspect heater (advanced): If drying remains poor, the heater element or thermostats may be failing and should be tested and replaced by a technician.
