The short answer
The useful thing to know about a Vesta dryer with this symptom is which cause to try first. Here that is A blocked or crushed vent, and the one to try last is A failed heating element. Everything near the top of the list is an owner check that costs nothing; the bottom of it is a service call.
What you actually observe
- The drum turns for a full cycle and the load comes out cold — The clearest version of this fault.
- It heats at first and then stops heating part way — Airflow and a cycling thermostat rather than a dead element.
- The machine and the room both get hot — Heat that is not leaving through the vent.
- NEAR MISS: it will not start at all — That is a door switch or power fault and it belongs on a different page.
Causes, most likely first on this build
- A blocked or crushed vent — A dryer has to push its moist air somewhere. A vent packed with lint, crushed behind the machine or blocked by a stuck outside flap leaves the heat trapped, and the safety devices then shut the heat down. 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.
- A lint filter sealed with residue — A filter that looks clean can be sealed by a film from dryer sheets and softener. Second here, because a light cabinet transmits everything it cannot absorb, which turns an installation problem into what sounds like a mechanical one.
- Only half the supply arriving — An electric dryer takes its motor and its element from different legs of its supply. Third, once the two above are clean: it is quick, free and it settles whether anything needs opening.
- A failed heating element — An element burns through and stops heating while everything else keeps working. 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
- Disconnect the vent at the machine and run it briefly — If it heats vented to the room, the duct is the fault.
- Run water over the lint filter mesh — Water sitting on the mesh means it is sealed.
- Reset both halves of the breaker fully — Half a supply turns the drum and heats nothing.
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 the mesh by running water through it — A sealed filter stops the air and the safety devices then stop the heat.
Tools: warm water, a soft brushAbout 10 min
- Pull the machine out, disconnect the vent hose and check it and the outside flap for lint — A blocked duct is the cause behind most failed thermal fuses, so clearing it is part of the repair.
Tools: a vacuum, a torchAbout 30 min
- STOP HERE before testing an element, a fuse or a gas valve — Those need a meter on live terminals or work on a gas train, and that is a service call.
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 once the filter and the vent are genuinely clear and the breaker has been fully reset, because everything left needs a meter on live terminals or work on a gas train. Clear the vent as part of the repair whatever the cause turns out to be: a thermal fuse that opened once will open again if nothing else changes.
