Drying performance does not confirm that washing was successful. The detergent, loading and wash programme need to be reviewed separately from the later moisture-removal stage.
Understanding this situation
A warm dry garment can still carry the original soil. A continuous cycle may make that distinction less obvious because there was no inspection between stages, particularly when a quick wash was selected for demanding laundry.
A useful next step
Record which stains remain, the wash programme and product dose. For a safe future suitable load, choose the correct cleaning process rather than extending drying. Report any wash warning or incomplete stage as a separate part of the enquiry.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
