Fabric selection controls the intended treatment, while the dryness target describes the desired finish within that programme. Both need to suit the load.
Understanding this situation
Choosing an intensive cotton programme for delicate synthetics simply because they remain damp can be inappropriate. An incorrect load or care choice is not corrected safely by selecting the strongest available option.
A useful next step
Match the care labels and model table first. Use a permitted finishing method for any remaining damp item. If appropriate loads now consistently miss their target, report the exact settings and result instead of progressively increasing treatment.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
