Heating can make an existing fragrance more noticeable, so a stronger scent during drying may relate to the wash products. It still needs to be distinguished from an unexpected burning or chemical appliance smell.
Understanding this situation
Review the detergent, conditioner and dose used before changing drying settings. A fragrance-heavy load is different from visible scorching, melted material or a smell from the controls.
A useful next step
Use only permitted products and doses. Stop use for concerning heat or electrical signs rather than assuming every smell is perfume. Record the product change and exact stage in the enquiry so the timing can be assessed accurately.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
