No. Fragrance can change what you notice without removing trapped food, residue or an appliance issue. First identify when and where the smell occurs.
Understanding this situation
A used dirty load waiting for a wash is different from an empty clean machine with a persistent odour. A burning or electrical smell belongs in a stop-use response rather than ordinary freshening.
A useful next step
Follow the approved filter and care routine while safe. Use accessories only where permitted. Report persistent unusual smells with any warning or drainage change, and do not add perfume or mixed cleaners to hide the evidence.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
