Only use such products where both the appliance and product instructions permit them. A product suitable for some separate dryers is not automatically suitable for a combined machine.
Understanding this situation
The item may pass through a shared drum and interact with the appliance's particular moisture-sensing or lint-management arrangement. It is especially important not to leave an unsuitable accessory in place for the subsequent wash.
A useful next step
Check the exact manual before adding sheets, balls or fragrance products. If an unexpected residue or drying change follows their introduction, record that timing. Do not combine multiple additives to compensate without identifying what the manufacturer allows.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
