A running motor sound does not prove that food is being processed and discharged correctly. Stop adding waste when the expected clearing does not occur, particularly if the sink begins to retain water.
What the observation tells you
Record the type and amount of food, the water flow and whether this is a new change. Do not push the contents down, attempt to adjust internal grinding parts or test it with harder material. Incorrect feeding and a mechanical or drainage problem require different remedies.
A useful next step
Use the model's approved owner checks only. If correct ordinary use still leaves waste, arrange assessment of the grinding and discharge path.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
