The short answer
What this symptom means on a Vesta dryer depends on how the dryer is built, and on this one the order runs like this. First — A restricted vent stretching every cycle. Last, and the only one that is a technician's job from the outset — A control board or timer fault. Start at the top: those checks are free and need nothing opened.
What you actually observe
- The cycle runs far longer than it used to — Almost always airflow.
- It stops early and the load is still damp — Almost always sensing.
- The time shown jumps around during the cycle — Normal on an automatic cycle.
- NEAR MISS: it runs the full cycle and never gets warm at all — That is a heating fault and it belongs on a different page.
Causes, most likely first on this build
- A restricted vent stretching every cycle — A dryer dries by moving moist air out. A vent that is partly blocked leaves that moisture in the drum, so the sensor keeps calling for more time and the cycle runs on and on. Ranked first on a Vesta: a value build gives you the least margin exactly where the load is highest, so the overloaded case is the normal case.
- An automatic cycle behaving automatically — An automatic cycle ends when the load is dry rather than after a set time, so the same load takes different lengths on different days. Second here, because a light cabinet transmits everything it cannot absorb, which turns an installation problem into what sounds like a mechanical one.
- A lint filter that is never fully cleared — A filter that looks clean can be sealed by a film of softener residue. Third, once the two above are clean: it is quick, free and it settles whether anything needs opening.
- A control board or timer fault — When the sequencing is at fault the machine stops or skips at the same point every time. Last, and the reason the order above matters: it is the least likely of the four and the only one that is a service call from the first minute.
Check in this order, and why
- Feel the exhaust outside while it runs — Weak flow is the whole story more often than not.
- Compare a timed cycle with an automatic one — A timed cycle that works points at sensing.
- Run water over the lint filter — If water sits on the mesh, it is sealed with residue.
What an owner can safely check
- Check how the machine stands and what it is standing on before anything else — A compact machine on a flat floor behaves; the same machine on an uneven one produces most of the complaints on this list.
Tools: an adjustable spannerAbout 15 min
- Clear the lint filter and test it by running water through the mesh — Water that sits on the mesh means a residue film is sealing it and no air is passing.
Tools: warm water, a soft brushAbout 10 min
- Go outside and feel the exhaust while the dryer runs — Weak or cold airflow at the outlet explains almost every long-cycle complaint.
About 10 min
- STOP HERE if it stops at the same point every time with airflow and sensing clear — That is where an owner check ends and a service call begins.
Before you open anything
Safety
Switch the machine off at its breaker or unplug it, and shut both taps, before opening any panel or filter. A capacitor can hold a charge after the power is off.
When to call a technician
Call when the vent is clear, the filter passes water and the sensor strips are clean, and the machine still ends cycles on wet cloth or runs indefinitely. Before that point everything is owner maintenance and costs nothing but time.

What is deliberately not on this page
This page is written for the Vesta dryer as a class, not for one family or model line. Where a family- or model-specific page exists for your machine it is linked above, and it is the more specific answer. Deliberately not here: error-code tables, motor and board part numbers and belt routings, all of which differ by family.
