The short answer
A dryer that ends early with damp laundry is almost never a heating fault. It is a machine that has either lost its airflow or is mis-reading how wet the load is, and those two causes cover the large majority of these complaints. On a Eurodesign dryer the place to start is the lint screen and the vent run, because the moisture-sensing and control chain decides when this dryer stops, so it outranks the heater on the list.
What you actually observe
- The machine stops mid-cycle and restarts if left to cool — A thermal cut-out opening on heat.
- Clothes dry eventually but take two or three cycles — Restriction rather than failure.
- The drum is hot and the laundry is damp at the end — Heat without air movement, which is the signature of a blocked vent.
- NEAR MISS: the drum is cold throughout — That is a heating failure and it has different causes.
Causes, most likely first on this brand
- A restricted lint screen or vent duct — Everything the dryer does depends on moving air through the drum and out of the building. Ranked first on a Eurodesign dryer: these are built-in units fitted into a cabinet opening, where the install decides the door line, the clearance and the drain fall, and where nothing inside the machine has usually failed at all.
- A thermal cut-out or cycling thermostat opening early — When airflow drops, the machine gets hotter than designed and a safety thermostat opens to stop it. Where it sits here: ranks below the airflow cause because it is usually the consequence of it rather than an independent fault.
- Moisture sensing that cannot read the load — Automatic cycles end when two metal strips in the drum stop seeing wet fabric bridging them. Where it sits here: the cause that explains a cycle ending in minutes, which no amount of vent clearing will ever fix.
- A failing timer, control board or intermittent door switch — A door switch that drops out as the machine vibrates stops the cycle dead and gives no clue why. Where it sits here: last, because it is the least common and because confirming it needs the machine measured rather than looked at.
Check in this order, and why
- Start at the lint screen and the vent run — It is the cause that ranks first on this kind of machine, so it is the check that ends the diagnosis most often and the one that costs least to make.
- Clean the lint screen and run a short cycle — Do it before anything else.
- Put a hand at the outside vent while it runs — You should feel a strong warm flow.
What an owner can safely do
- Clean the screen and the housing below it — Pull the screen, wash it with warm water and a brush if it has a softener film, and vacuum the slot it sits in.
Tools: vacuum, soft brushAbout 15 min
- Clear the vent run end to end — Disconnect at both ends, brush the whole run through, and confirm the outside flap swings freely.
Tools: vent brush, screwdriverAbout 45 min
- Clean the moisture sensor strips — Wipe the two metal bars inside the drum opening with a cloth and a little white vinegar, then dry them.
Tools: cloth, white vinegarAbout 10 min
- STOP HERE before testing thermostats — Thermostats and thermal cut-outs are measured on a dismantled machine with a meter, and a cut-out that has opened has a reason that must be found first.
Before you open anything
Safety
Unplug the dryer or switch off its breaker before removing any panel; a capacitor can hold a charge after the power is off. A blocked vent is the reason dryers catch fire, so treat a hot cabinet and a weak outside flow as urgent rather than as an inconvenience. On a gas dryer, close the gas shut-off before moving the machine, and if you smell gas: do not switch anything on or off, leave the building and call the gas utility from outside.
When to call a technician
Call when the vent is proven clear, the sensor strips are clean and the cycle still ends early, or when a thermal cut-out has opened and you have not found the restriction that opened it. A machine that keeps tripping its own safety device is telling you something that should not be reset and ignored.

What this page does not cover
This page covers Eurodesign dryers as a class, not one family or model line. Where a family- or model-specific page exists for your unit, that is the more specific answer and the one to read first. Deliberately not here: thermostat ratings, sensor part numbers and the duct length tables, all of which differ by family.
