Dots indicate the permitted drying treatment under the relevant care-label system. They need to be interpreted together with the symbol and the appliance's available programmes.
Understanding this situation
A fabric may allow tumble drying only under restricted conditions. Choosing a programme by its name without checking the manual can give the wrong impression about how gentle or warm it is.
A useful next step
Match the label to a supported setting, and use the prescribed alternative if no suitable programme is available. Do not assume that a shorter time makes a hotter programme equivalent to the garment's permitted treatment.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
