What this means on these models
Bosch groups all three models below under the WGH label. They are diagnosed as one platform because the drain path, the door lock and the suspension are laid out the same way across the line.
Symptoms on this family
- The machine will not reach its final spin — Either it cannot balance the load or it cannot drain fully, and both are covered by the cycle and drainage pages respectively.
- The drum is full of water at the end of the programme — A drain gate that was never satisfied. The drainage page for this family works the filter, impeller and hose chain in order.
- The cycle only fails on hot programmes — A heating-step fault, which is a narrow and useful finding. The cycle fault page covers that branch.
- Foam at the detergent drawer during fill — Dosing rather than a fault, and the leak page for this family says why the drawer route makes it look like a machine problem.
The ranking that applies to this platform
- Internal hose clip relaxed with vibration — A drum machine shakes its own plumbing loose over years, and the sump and pump clips are the usual ones to go.
- Restricted fill from part-closed taps or blocked inlet filters — The machine waits for water it is not getting and appears to be doing nothing at all.
- Door lock not confirming — The gate before every other step. A door that looks shut but has not latched stops the machine dead with nothing broken.
- Unbalanced or under-loaded drum — The machine will not spin what it cannot balance, so it retries, extends the cycle and finally gives up with wet clothes.

Problem classes on this family, most reported first
General guidance| Problem class | Relative frequency on this family | What it means for the owner |
|---|---|---|
| Drain path: filter, impeller, hose | Leading cluster on this family | Owner-fixable on every model in this line |
| Load balance and suspension | Common | Free to test with an empty spin |
| Water in: taps, valves, drawer | Common | Mostly dosing and installation rather than parts |
| Door lock and start chain | Less common | Checked before any panel comes off |
| Heating and sensing | Less common | Programme-specific symptoms place it quickly |
| Rotating assembly: bearing, motor | Least common | Bench work, and the only expensive class here |
Based on: No measured denominator: the fact bundle for this family carries no component share, so this ordering is a technician ranking of problem classes and not a share of reports.
Before you open anything
Safety
Unplug the machine and let it stand before you reach inside. The heating element and the motor stay hot after a long cycle, and the drum can free-wheel for a while after the cycle ends.
When to call a technician
Call if the fault only appears on one programme. Programme-specific behaviour points at the control or at a sensor rather than at anything mechanical, and that is diagnosed against the service manual rather than by inspection.
