Tumble dryer not drying: causes and fixes
A tumble dryer that no longer dries properly is, in the vast majority of cases, suffering from an airflow problem. The filters and the condenser are what to check before anything else.
The causes, from most to least common
Check them in this order: the first ones are free and solve the majority of cases.
- 1
Saturated lint filter
very commonHow to check: Open the filter in the door opening: even a thin film of lint is enough to cut airflow sharply.
Fix: Clean it after every cycle. Once a month, rinse it under lukewarm water to remove the invisible film left by fabric softener.
EasyEstimated cost: 0 € - 2
Clogged condenser
very commonHow to check: Behind the flap at the bottom of the machine: the fins must be clean and air must be able to pass.
Fix: Rinse the condenser in lukewarm water (removable models) or clean the heat-pump filters, monthly.
EasyEstimated cost: 0 € - 3
Full condensate tank
commonHow to check: A light usually comes on, but not always: check the tank even without a warning.
Fix: Empty the tank after each cycle, or connect direct drainage if your model allows it.
EasyEstimated cost: 0 € - 4
Dirty humidity sensor
commonHow to check: The machine stops early thinking the laundry is dry when it is still damp. The metal sensors in the drum are scaled up.
Fix: Clean the sensors with white vinegar and a cloth.
EasyEstimated cost: 0 € - 5
Failed heating element or compressor
less commonHow to check: The air blown stays cold throughout the cycle despite clean filters.
Fix: Professional diagnosis. On a heat-pump model, a compressor failure often costs more than half the price of a new machine.
ProfessionalEstimated cost: 150 to 400 €
If you take this out-of-warranty tumble dryer to a QualiRépar-certified repairer, 50€ comes off the invoice.
| Repair by a professional | 150 to 400 € |
| Repair bonus deducted | - 50 € |
| What you pay | 100 to 350 € |
Indicative estimate: the real price depends on the part, the model and the call-out. The bonus can never exceed the invoice total.
How to claim the repair bonus →When to call a professional
If the air stays cold despite perfectly clean filters and condenser, the element or the heating circuit is at fault: call a repairer. On a heat-pump model over 10 years old, weigh the cost against a new one.

Why is my tumble dryer no longer drying properly?
In the vast majority of cases air can no longer circulate: a saturated lint filter or a clogged condenser. Clean both before assuming a fault. A scaled-up humidity sensor can also stop the cycle too early.
How often should you clean a tumble dryer condenser?
Once a month with regular use. The lint filter, though, must be emptied after every single cycle: it is the most important maintenance this appliance needs.
Your tumble dryer may be nearing the end of its life: a tumble dryer lasts 8 to 12 years. Beyond that, an expensive repair is harder to justify.
