Only follow a manufacturer-documented owner procedure for the exact model. Hidden menus and service sequences from unrelated machines can change settings without resolving the fault.
Understanding this situation
A poor drying result does not prove that calibration is needed. Load, selected target, maintenance and a possible technical fault all require context, and a reset can remove useful evidence.
A useful next step
Record the normal programme and result first. Use official model guidance and seek assessment where necessary. Do not enter undocumented service modes, bypass sensors or change protected settings to force a longer or hotter drying cycle.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
