Loose fasteners can catch other textiles or make contact with the drum during normal movement. Preparation helps separate a garment-handling problem from a new scraping or snagging fault in the machine.
Understanding this situation
Follow each garment's own instructions for closing zips, fastening hooks or using a permitted laundry bag. Check pockets for hard objects before loading. A protective bag is not permission to wash something whose label prohibits machine treatment, and it cannot make a broken sharp component safe to include.
A useful next step
If damage has already occurred, inspect the affected garment and the items washed with it without probing the machine's internal spaces. Record whether the marks follow a particular fastener or occur across unrelated loads. A rough edge or snag felt on an accessible surface should be assessed rather than smoothed with tools or ignored during further washes.

Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
