Put the normal operating control in its off position and keep the sink opening clear. Do not assume an interrupted grinding session will remain stopped when the electricity returns.
What the observation tells you
Power restoration is different from clearing the material that was being processed. There may still be food in the chamber, and another person may use the sink before you return. Make the appliance's status clear to the household.
A useful next step
After power returns, follow the model's documented sequence only when the water supply, drain and appliance are suitable for normal use. An electrical trip local to the disposer requires assessment rather than treating it as an ordinary power cut.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
