Heat resistance is not the only consideration. The cookware's surface treatment and seasoning can have specific cleaning requirements that differ from dishwasher conditions.
Understanding this situation
A pan suitable for high cooking temperatures is not automatically suitable for prolonged detergent washing. Coated or enamelled versions also need their own manufacturer's instructions rather than a rule based only on the metal.
A useful next step
Use the cookware's specified care method. Do not try repeated machine cycles to remove a finish or restore a damaged surface. If the pan changes colour or develops corrosion, distinguish that material-care issue from poor cleaning of ordinary suitable dishes.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
