Adding fragrance can obscure when an odour appears without addressing its cause. First distinguish a fabric smell, retained lint or ordinary maintenance issue from a burning or electrical smell.
Understanding this situation
The timing matters: before loading, during washing, at the start of drying or only after storage. An unsafe smell requires stopping, while routine care should follow the exact model rather than an improvised chemical treatment.
A useful next step
Record the stage and recent products, then use only permitted maintenance. Do not mix cleaners or increase conditioner beyond its limit. If an unusual smell persists or accompanies a warning, overheating or leakage, seek assessment before further cycles.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
