What to check before you call
Safe observations first. Stop if anything involves smoke, gas, water near electricity, or a panel you would need to remove.

When an ASKO dryer leaves some items dry and others damp, the cause is usually airflow or the way the load sits in the drum, not a failed heater. Check the lint filter, split the load by fabric weight, and look at the exhaust path first. If the drum never warms at all, or the dryer smells hot or burnt, stop using it and book a diagnosis.
What is the difference between uneven drying and no heat?
Uneven drying means the dryer runs and makes warm air that does not reach every item equally. No heat means the drum never warms at all.
These two complaints sound alike but point in different directions. Uneven drying means the dryer is running and producing warm air, yet the air or the tumbling does not reach every item equally. Thick seams, towels, jeans waistbands and bundled sheets tend to stay damp while thin garments finish early. No heat at all means the air never warms, and that question needs test equipment that an owner should not try to improvise.
A useful first test is simple: feel the clothes at the end of a normal cycle. If everything is slightly warm and a few heavy pieces are damp, think load and airflow. If the whole load comes out cool and wet, note it down and plan a visit rather than running cycle after cycle.
How does an ASKO dryer decide a load is finished?
An ASKO laundry brochure describes Sensi Dry as a function that determines the drying time automatically and stops the program when the clothes are dry. A program that ends on its own judgment can finish while one thick item is still damp, especially in a mixed load. Sorting towels and bedding away from light garments gives the program a more consistent load to judge. Your manual lists the programs available on your model, so read it before assuming something is broken.
Can lint cause uneven drying?
Lint leads to longer drying times, so empty the Lint Trap after every drying program and keep the exhaust path clear.
The same brochure explains that lint leads to longer drying times and that the Lint Trap should be emptied after every drying program. The cleaning guide says to empty the lint filter after every load, which also keeps the room cooler, and to rinse it in the sink once a month with mild detergent and let it dry before reinstalling. A partly clogged filter changes the airflow around the whole drum and produces exactly the patchy results described here.
For a vented model, one set of installation instructions says the dryer must exhaust outdoors and that excess duct length and bends impede drying performance. It also describes rigid metal duct, a limit on total length with a deduction for each elbow, and a short limit on flexible transition duct. Check your own installation instructions for the figures that apply. What an owner can see from the outside is whether the duct is crushed behind the dryer and whether the outdoor opening is clear of lint.
On condenser models the cleaning guide describes a condenser cleaning routine on a recurring schedule. Follow the steps in your manual for that model, since access differs.
Where the dryer sits
The design guide notes that closet or enclosure installs need a door that is vented, louvered or left open, because insufficient ventilation significantly reduces performance. The dryer installation instructions also say not to place it in a very small room, since drying takes longer there, and never to block the air vents. If the dryer lives in a closet, run one cycle with the door fully open and compare the result.
A simple way to run the comparison
Pick two ordinary loads: one of mixed clothes and one of towels only. Run each on the program you normally use, with a clean filter, and write down which items stayed damp and whether the outside of the dryer felt unusually hot. If the towel-only load dries evenly but the mixed load does not, the sensing and the load mix are the likely story. If both loads fail in the same spots, the airflow and the room deserve attention before anything else.
What the checks do and do not prove
| What you see | What it can point to | What you can check |
|---|---|---|
| Thick items damp, light items dry | Heavy mixed load or items bunching | Split the load by fabric weight and rerun |
| Every load takes longer than before | Lint buildup or restricted exhaust | Empty and rinse the lint filter, inspect the visible duct and outdoor opening |
| Clothes damp only when dryer is in a closet | Poor ventilation around the dryer | Run a cycle with the door open |
| Program ends with a few damp pieces | Automatic drying stopping early on a mixed load | Choose a program suited to the fabric and keep loads uniform |
| Drum never gets warm | A heating or control problem | Note the settings and any code, then book a diagnosis |
A clean filter and a better load that fix the problem prove the cause was airflow. A repeat failure after those steps proves only that the simple causes are ruled out, not which part has failed.
When to stop
Do not open the cabinet to look for a heating part, and do not run the dryer with the duct disconnected. Stop and call for service if the dryer trips a breaker, smells hot or burnt, or makes a new grinding noise. Have the model number, the programs you used and the results of the checks above ready when you book.
Frequently asked questions
Why are the seams of my jeans still damp?
Seams and waistbands are thick, so they hold moisture longest. A smaller load or a longer program usually helps, and a clean lint filter keeps the airflow consistent.
Can a long duct cause uneven drying?
Installation instructions for a vented ASKO model say excess length and bends impede drying performance. If the dryer was moved or the duct was changed recently, compare the run against your instructions.
Should I keep restarting the cycle until everything is dry?
One extra cycle is reasonable. Repeated restarts hide the pattern, so note which loads fail instead.
Is uneven drying a sign of a broken sensor?
Not by itself. Mixed loads and lint are far more common explanations to rule out before suspecting any part.
