What this family is
If your Bosch dryer carries a model number starting WTG, this is the family page for it. The table below is the whole of what the spine says about the platform; the rest of this page is what goes wrong on dryers of this kind and where each fault is answered in detail.
What goes wrong on these models, and where each one is answered
- A new noise: rumble, squeal, thump or rattle — A noise that arrived rather than one that was always there, and that tracks drum rotation. See: Bosch WTG Dryer: Abnormal Noise or Vibration.
- The cycle stops early, pauses, or will not complete — Time that stalls, a cycle that ends with the load still wet, or a machine that stops mid-run. See: Bosch WTG Dryer: Cycle Will Not Run or Complete.
- The drum turns but the load comes out damp or cold — Tumbling with no heat, or a cycle that runs its full length and leaves the load heavy. See: Bosch WTG Dryer: Not Heating.
Problem classes in order on the WTG family
- Will not start — First on the seven models below by call volume, and the class most often resolved without a part: a latch that no longer closes the switch, or a lock left on. — Owner: Mostly yes
- Heat and the air path — Second, and the class with the safety tail: lint packed around a heat source is a fire risk, not a performance complaint. — Owner: Partly
- Cycle behaviour — Third. Early finishes and stalled cycles, almost always maintenance rather than failure. — Owner: Mostly yes

Fault classes in order, without a share — Ordering only - no measured share: no snapshot in this slice carries a component share for the WTG family.
General guidance| Fault class | Where it ranks on this family | Owner-fixable at all? |
|---|---|---|
| Will not start | First | Mostly yes |
| Heat and the air path | Second | Partly |
| Cycle behaviour | Third | Mostly yes |
What is owner-fixable on these models
Filters, ducting, the reservoir if your model has one, levelling, the door and the breaker are all owner work on these models. The thermal chain, the drum supports, the drive and the control are not: they sit behind fixed panels and the drum has to be supported to reach most of them.
