Stop adding water and seek advice if the system may be obstructed. An object that has left the bowl may still be inside the unit or discharge route.
What the observation means
Do not put hands or tools into the macerator, and do not assume its cutting mechanism can safely process arbitrary material.
A useful next step
Tell the service team what the object was and when it entered. Accurate information helps planning and is more useful than repeated test flushes. Keep connected fixtures unused where drainage or operation is uncertain, and avoid chemical attempts to dissolve the object.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
