The short answer
The Ariston TVM dryer family covers a single listing in the roster below, and on that platform the sensor bars and the vent run explain most of these. A cycle that will not finish on a dryer is almost always the air path rather than the timer that appears to be at fault. Where the machine stops within minutes of starting, that is closer to an overheat cut-out than to a cycle fault.
The observables
- The cycle runs far longer than it used to for the same load — Moisture is not leaving the machine fast enough. That is airflow: the filter, the housing behind it, the duct or the vent run, in that order of likelihood.
- The machine runs and runs and never stops on its own — An automatic programme that never reaches its dry threshold will run to its maximum. The load is genuinely not drying, and the reason is heat or airflow rather than the timer.
- The machine stops early and the cabinet is hot to the touch — A thermal cut-out has opened because the machine could not shed its heat. That is a restricted vent presenting in its most serious form and it should not be reset and rerun.
- The display shows a code and stops — The code names the step or the condition the machine gave up on. On most dryers that means a temperature it could not reach, or one it reached too quickly.
- NEAR MISS — the load was far wetter than usual going in — Laundry that came out of a slow spin carries much more water, so the dryer is doing more work rather than failing at the same work.
Causes, most likely first on the TVM line
- Restricted airflow: filter, filter housing, duct or vent run — Ranked first here, because a dryer works by moving heated air through the load and out of the building, so anything that slows that air lengthens every cycle, and lint accumulates in four different places along the route. This label covers one listing, so there is no variant to rule out first and the order below goes straight at the fault.
- Overloading, or laundry that arrived too wet — Second here, because a drum packed past the point where the load can tumble freely dries nothing evenly, and laundry that came out of a washer without a proper spin can double the work the dryer has to do.
- Heating circuit failing intermittently — Third here: a machine that heats for part of the cycle and then stops produces a load that is warm and damp, and it sits below the airflow causes because a complete heating failure is a different page.
- Control or programme selector fault — Last here, because almost every cycle that will not complete is the machine reporting a real condition, and a control that has genuinely failed is rare compared with a duct full of lint.
What to check first, second, third
- Clean the lint filter and look into its housing — A filter that looks clean can still be blinded by a film from dryer sheets. Wash it in warm water, and check the housing beneath it with a torch while it is out. The order matters more than the list: each step above rules out a region of the TVM line before the next one costs anything.
- Check the exhaust at the outside vent while running — There should be a strong, warm flow at the outlet. A weak flow with the machine running names the duct or the vent run without anything being opened.
- Pull the machine out and check the duct behind it — A flexible duct crushed between the cabinet and the wall is one of the most common finds on a dryer, and it is created every time the machine is pushed back into place.
Safety first
Safety
Let the machine cool, then unplug the appliance or switch off its breaker before the filter housing or any panel is opened — a capacitor can hold a charge after the power is off. A thermal cut-out that has opened has done so for a reason, and a machine that trips it repeatedly is telling you the vent is blocked. Clear the whole run, not just the end you can reach, and never replace a protective device to make a machine run again.

When to call a technician
Call if automatic programmes fail with clean sensor bars while timed programmes dry normally, because at that point the sensing circuit rather than the sensor surface is the suspect. A long cycle is an efficiency problem. A machine that stops early with a hot cabinet is a safety problem, and the two should not be treated the same way.
