Long fibres can behave differently from soft food fragments, so follow the restrictions for the actual disposer rather than a general claim that all food is suitable. Models have different permitted waste lists.
What the observation tells you
Corn husks, tough stems and similar fibrous material can remain as strands instead of clearing like small soft scraps. Chopping them does not automatically make a prohibited item acceptable. A more powerful motor rating also does not override the manufacturer's instructions.
A useful next step
Put uncertain fibrous waste in the appropriate food-waste collection. If a fibre-heavy load preceded a stall, tell the engineer what was used rather than trying repeated starts.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
