Damp laundry after a cycle does not automatically mean a failed heat pump. Programme choice, load size, filter maintenance, drainage and room conditions can affect drying. First identify whether the machine is vented, condenser or heat-pump, then use its own manual.
Check the programme and load
Use a programme suitable for the fabric and required dryness. Do not compare an ironing-dry setting with cupboard-dry results. Separate very different fabric weights and stay within the programme’s load limit. Laundry that leaves the washer unusually wet adds drying time and may indicate a washer spin problem.
Clean the correct filters
Switch off and let the machine cool before maintenance. Remove lint at the interval specified by the manufacturer, commonly after each load for the door filter. Filter number and placement vary; not every heat-pump dryer has two owner-cleanable filters. Never run the dryer without correctly fitted filters.
Heat exchangers are not all removable
Some condenser units can be removed and rinsed; many heat-pump systems cannot. Follow only the exact model’s procedure. Do not pull out a sealed heat exchanger, bend its fins or spray water into electrical sections. Empty the condensate tank or inspect accessible drain routing as instructed.
When to request a repair
Stop for a burning smell, scorching, damaged cable or breaker trips. If approved maintenance and the correct programme do not help, record the code and cycle behaviour for a technician. Heating, sensing, airflow and control faults require diagnosis before choosing parts.
