Do not use forceful hand spinning or dismantling as a general diagnosis method. A freely moving drum does not prove that every component is healthy, and resistance does not identify a single failure.
Understanding this situation
Owner checks should remain within the exact manual, with the appliance safe and stationary. Sharp debris, damaged surfaces or a trapped garment can make exploratory handling unwise, especially if the machine has already scraped or snagged clothing.
A useful next step
Describe the changed behaviour from ordinary use instead. If a manual permits a simple accessible inspection, follow its limits and stop if anything feels unsafe. Never reach into a powered or moving drum, or attempt to run the appliance with a guard removed.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
