The point at which the smell becomes noticeable helps separate washing, delayed unloading and drying conditions. A result first noticed hours later cannot automatically be attributed to the washer.
Understanding this situation
Consider how long the damp laundry waited, whether it was tightly bundled and the drying method used. Compare that with its condition immediately after the wash, using existing observations rather than repeatedly processing the same items.
A useful next step
Keep a simple timeline for the enquiry and follow garment-safe care. If the machine itself has an unusual smell before use, mention that separately. A persistent problem across promptly handled loads may need the washing and drying routines reviewed together.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
