Symptom
Miele dryer cycles are getting longer
A heat-pump dryer is slower than a vented one by design, and that is not a problem. A cycle that is getting steadily longer than it used to be is — and it is nearly always the air path.

Four ordinary causes
What this usually turns out to be
Cheapest and commonest first, which is also the order we check them in. They sit hundreds of dollars apart, and only the unit settles which one is yours.
-
The filters and condenser
Restricted airflow, which the machine works around rather than reporting.
Dryer condensate & filter service from $135 -
The room
A closed closet with no ventilation. Not a repair, and worth knowing.
Appliance installation from $225 -
The moisture sensors
Reading late, so the cycle runs on.
Dryer condensate & filter service from $135 -
The heat pump itself
Losing capacity. The last thing to consider, not the first.

How it shows up
What people describe when they call
Two shortcuts
Narrow it down before anybody arrives
A description of the behaviour leaves a few possible causes. A code names the subsystem, and the model number says which parts to bring. Either one shortens the visit; both together usually settle it.

About Miele dryer cycles are getting longer
The fastest diagnosis is the code
Both filters and the condenser block, in that order. If the machine is in a closed closet, open the door while it runs and see whether the cycle shortens — a ventless dryer takes its air from the room, and a South Florida laundry closet in August has very little to give it.
Slow is normal. Slower is not.
A heat-pump dryer runs cooler and longer than a vented one by design, and that is why the clothes last. What matters is the trend: cycles that are noticeably longer than they were a year ago are telling you the air path has closed up, and that is filters and the condenser block rather than a failing machine.
The test that costs nothing
Run a cycle with the laundry room door open. If it finishes measurably sooner, the machine is short of air where it stands, and that is an installation answer rather than a repair.
