Follow the model's shutdown, cleaning and door-position instructions. Leaving food residue sealed inside an unused cabinet can create an avoidable odour or hygiene problem.
What the observation tells you
The appliance must be emptied properly, not simply switched off with forgotten items in a drawer. Safe isolation and securing the appliance against child access also matter. A shutdown arrangement suitable for an occupied home may need extra care in a vacant property.
A useful next step
Clean and dry permitted surfaces and follow the prescribed ventilation arrangement. Keep the appliance secure. When returning it to service, complete the documented restart checks before relying on it for food.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
