After drying, a mark may look or feel different from how it appeared straight after washing. Inspecting the washed result first can help preserve a clearer account of whether the original stain was removed.
Understanding this situation
The garment and stain-removal product instructions govern further treatment. A washer-dryer cannot determine whether every stain should be exposed to a subsequent heated stage, and more heat is not a stain-removal substitute.
A useful next step
Where appropriate, use wash-only so the result can be checked before permitted drying. If damage or marking occurs, record both stages and products. Do not repeatedly wash and dry a delicate item to establish a machine fault.

Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
