No. Do not push tools through the drum or into concealed air or water passages. The visible perforations are not a general owner-maintenance access route.
Understanding this situation
Lint handling varies by model, and forcing material into an unseen space can create damage or move a blockage without removing it. A long brush intended for a different appliance is not automatically suitable.
A useful next step
Use only the cleaning points and method stated in the manual with the machine safe. If the documented routine does not resolve persistent lint transfer or drying changes, arrange assessment. Explain the maintenance already completed without improvising further dismantling.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
