Lint collected during one load can restrict the next load's intended airflow. Routine filter cleaning is part of using the dryer correctly, not a repair for every possible drying fault.
Understanding this situation
Use the exact manual's removal and cleaning method when the appliance is safe. A reminder light does not replace the routine, and different filter assemblies can need different handling.
A useful next step
Refit the filter properly before use. If drying remains abnormal after permitted maintenance, report the programme and result rather than removing extra guards. Never operate without the filter because it seems to improve airflow.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
