The short answer
This page profiles the Bosch WNA-series dryer - the models whose number carries the WNA prefix - and routes you to the page for your fault. A single-drum washer-dryer - this designation denotes a condensing platform that washes and dries in one drum, so the drying air is conditioned inside a machine that also has to deal with wash water.
Where each fault is answered
- A new noise — Placed by rhythm: a drum note, an airflow note and a circuit note are three faults. — Slug: bosch-bosch-dryer-wna-dryer-abnormal-noise-2 — Title: Bosch WNA-series dryer making a new noise: what it is and where it comes from
- Cycles ending early or running long — A sensor programme working from a restricted loop or a filmed sensor. — Slug: bosch-bosch-dryer-wna-dryer-cycle-fault-2 — Title: Bosch WNA-series dryer cycle stopping early or running forever: why
- Tumbling without drying — Airflow rather than a failed heat source, almost every time on this platform. — Slug: bosch-bosch-dryer-wna-dryer-heating-failure-2 — Title: Bosch WNA-series dryer not heating: what to check and in what order
- The machine will not start — The door, a full tank or a lock-out, in that order. — Slug: bosch-bosch-dryer-wna-dryer-wont-start-2 — Title: Bosch WNA-series dryer that will not start: what to rule out first
Problem classes in order
- A new noise — Commonest here: this cabinet carries running gear a vented dryer has not got, some of it meant to be audible. No share is claimed for it.
- Cycles ending early or running long — Second here: a condensing loop turns every restriction into an odd-looking cycle, and both filters in it are owner jobs that get skipped. No share is claimed for it.
- Tumbling without drying — Third here: heat is useless without airflow, so a restriction reads as no heat long before anything electrical fails. No share is claimed for it.
- The machine will not start — Least common of the set: the interlocks include one a vented dryer has no equivalent for, and it surprises owners rather than failing. No share is claimed for it.

Owner fix or service call
The lint filter, the exchanger behind the lower flap, the tank and the feet are owner ground here. The line is the cabinet: a meter on the heat source, a belt or anything in the refrigerant circuit means panels off.
