The short answer
The Blomberg BLDV dryers handle this fault differently from the brand as a whole, because of where this platform puts the components involved and how they are reached. Drum turning, no heat: that combination puts restricted airflow at the top of the list and a failed element a long way below it. Treat a blocked vent as urgent regardless of what else you find — it is a fire risk, not only a performance problem.
What you observe on these models
- The drum turns normally but the load comes out cold and damp — Mechanically healthy, thermally not — the classic presentation.
- Very little air comes out at the outside vent hood — A direct measure of the restriction, and the fastest check on this page.
- It heated on the last load and then stopped completely — A cut-out that has opened, which is a symptom of a restriction rather than a fault in itself.
- NEAR MISS — the drum does not turn at all — That is a start or drive fault, not a heat fault. The won't-start page covers it.
Causes, most likely first on this family
- Cycle selection or sensor calibration — Last on the list, and it is the one to check before anything else precisely because it costs one look at the panel.
- Gas supply off, or the burner not igniting — Fifth, and it is checked at the valve rather than inside the appliance.
- Heating element or gas igniter failed — Fourth: elements and igniters do fail, but far less often than the airflow path in front of them blocks, which is why they sit here rather than at the top.
- Why this order is not the brand-generic order — Because the layout differs. On these models the first check is chosen for what it eliminates per minute of work rather than for its standalone probability, and that is what separates a family-level ranking from a brand-level one.
Check in this order, and why
- Check the programme selected — An air-fluff or no-heat setting produces a perfect tumble with no heat by design, and it is easy to select accidentally.
- On a gas machine, confirm the supply valve is open — The handle should be in line with the pipe. Do not go further than the valve.
- Disconnect the duct at the machine and run it briefly — If it heats normally with the duct off, the restriction is in the vent run and not in the appliance.
- The access logic behind this sequence — Each step above is ordered by how much it rules out per minute spent. On this family that puts the external and audible checks first and anything requiring a panel last, which is the opposite of the order most people work in instinctively.
Before you open anything
Safety
Unplug the dryer or switch off its breaker before removing any panel or reaching into the lint path. On a gas machine, if you ever smell gas: do not switch anything on or off, leave the building, and call the gas utility or 911 from outside.
When to call a technician
Call once the whole air path is proven clear and the fault survives it. Call immediately for any burning smell, any scorched lint, or any smell of gas — and in the gas case, leave the building first and call from outside without touching a switch.

What this page generalizes over
This page covers the Blomberg BLDV dryers as a family rather than one model. The models in it are close enough to share a diagnosis, but not identical, so where a detail depends on the individual model — a component position, a part number — it is not stated here. The family pages and the brand-level article linked below give the surrounding context.
