Turn the operating control off and keep further scraps out while you work out why the session stopped. A planned interruption, lost water supply and an electrical trip need different responses.
What the observation tells you
If power failed, leave the control off so restoration does not unexpectedly restart the appliance. If it stopped with a hum, burning smell, leak or protective trip, do not treat the interruption as a normal pause. Record what happened and arrange appropriate assessment.
A useful next step
Resume only when the supply and appliance are known to be suitable for ordinary use, following the exact model's restart instructions and water requirements.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
