Yes. A damaged seam in a cushion, toy or padded textile can release material during movement, even if the item was originally washable. Condition matters alongside the label.
Understanding this situation
Escaped filling can spread through the load and create a different issue from normal textile lint. Do not continue processing more laundry while substantial loose material remains, or push debris through openings to clear the visible area.
A useful next step
Let the appliance finish or stop only according to safe documented controls. Once safe, obtain the model's appropriate cleaning guidance and report any new noise or drainage problem. Repair the item before any permitted future washing.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
