The warning may cease without proving that the underlying condition is resolved. Automatic silence or an intermittent fault can be misleading.
What the observation means
A lowered level, stopped inflow or changed power state are different possibilities. None should be assumed from the absence of sound.
A useful next step
Follow the unit's documented recovery guidance and obtain assessment where the cause is uncertain. Keep connected fixtures unavailable until safe use is established. Do not remove the notice because someone heard the motor run once or because the floor currently appears dry.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
