The control expects a defined cooking arrangement. Too little liquid, unsuitable cookware or a different lid setup can change what it detects.
What the observation means
A sensor feature is not a universal protection against a pan boiling dry. The food and cookware instructions remain relevant.
A useful next step
Use the programme only within its stated conditions and remain attentive. Record the quantity and vessel if it behaves unexpectedly. Do not deliberately let a pan run dry to test the feature or assume that a completion beep confirms food safety.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
