The window cannot show moisture retained in seams, fillings or layered areas. It may also distort appearance through condensation or reflections.
Understanding this situation
A load tumbling freely does not prove that every item has reached the selected target. Conversely, a glass surface that looks damp is not a direct measurement of the fabric condition.
A useful next step
Let the safe programme finish and check the actual items using their care guidance. Describe whether dampness is widespread or confined to thick areas. Avoid interrupting repeatedly or reaching into a moving drum to assess the result.
