The short answer
The Blomberg DHP dryers are grouped as one platform, and that grouping changes this diagnosis: the same causes apply, in a different order, for reasons of layout. A dryer that shuts down partway through has usually overheated or has decided the load is already dry. Both are the machine protecting something rather than failing. The motor-overheat branch is the one where repeated retries make things worse rather than better.
What you observe on these models
- The drum is very hot when it stops — Heat that cannot leave, which is an airflow problem presenting as a cycle fault.
- Small loads dry fine but large ones stop early — Airflow that is adequate for a light load and not for a heavy one.
- Automatic cycles stop early but timed cycles run through — Moisture sensing rather than anything thermal or mechanical.
- NEAR MISS — it runs the full cycle but produces no heat — A complete cycle with no heat is a heating fault, not a cycle fault.
Causes, most likely first on this family
- Motor thermal protector cutting out — Third: a motor working against restricted airflow or a heavy load will overheat, and its protector stops everything until it cools.
- Moisture sensor bars coated with residue — Second on likelihood, and it is cleaned with a cloth rather than replaced.
- Restricted airflow overheating the cabinet — First on the list because it also explains the secondary clues — a hot drum, long cycles, and a machine that restarts once it has cooled.
- What moves, and why it moves, on this platform — Two things reorder this list for these models: where the family puts the component, and how much has to come apart to reach it. A cause that is two minutes away on this platform is worth checking before one that is an hour away, even when the second is marginally more likely.
Check in this order, and why
- Wait and see how long it takes to restart — An immediate restart is not a thermal protector. A twenty-minute wait is.
- Go outside and check the airflow at the vent hood — Weak airflow explains almost every thermal version of this fault, and it is checked in under a minute.
- Run a timed cycle instead of an automatic one — If a timed cycle completes and an automatic one does not, the fault is in moisture sensing and nowhere else.
- What this family's layout decides — The construction of these models determines what can be confirmed quickly and what cannot, and the order above follows that directly. It is not a generic checklist reordered; it is the sequence that this platform actually rewards.
Before you open anything
Safety
Power off before working on the lint path. On a gas dryer the burner, the igniter and the gas valve are not owner checks; if you smell gas, do not operate any switch — leave the building and call the gas utility or 911 from outside.
When to call a technician
Call when the vent, the duct, the screen housing and the hood are all clear and the machine still will not heat or still stops early. Call at once if lint anywhere shows heat damage.

What this page generalizes over
What this page generalizes over is the set of Blomberg dryer models carrying the DHP prefix. They share a platform and therefore a fault pattern; they do not share every part. Anything that varies model by model is deliberately absent, and the pages linked below give both the wider and the narrower view.
