Not necessarily. The toilet's flushing action and the pump's wastewater removal are separate stages. The cistern and bowl behaviour should be described independently.
What the observation means
A small flush volume or toilet mechanism issue can look different from water failing to leave after the unit runs. Neither observation identifies a motor component remotely.
A useful next step
Record whether the bowl received its usual flush and what happened afterwards. Do not keep flushing a poorly clearing system. Arrange the appropriate assessment without assuming a pump replacement will correct a toilet-side problem.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
