Follow the manufacturer's care and usage guidance rather than inventing a daily empty-running schedule. Good clearing after actual use and suitable cleaning matter more than repeatedly starting an appliance with no task to perform.
What the observation tells you
If the disposer will remain unused for a long period, consult its storage advice. Do not leave food inside and rely on a timed motor run to clear it later, or fit an automatic controller to operate unattended. Water requirements still apply whenever the motor runs.
A useful next step
Investigate a unit that becomes difficult to start between sessions. Increasing the number of starts is not a repair for that change.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
