Non-stick surfaces and the complete pan construction vary. Dishwasher compatibility should come from the cookware maker rather than a general rule about the coating name.
Understanding this situation
A pan can be physically robust while its finish needs gentler care. Scratching, worn coating or damaged handles are separate concerns that a wash cannot correct.
A useful next step
Use the permitted cleaning method and load suitable pieces without contact that can scratch them. If the finish changes, retain the programme and detergent details. Do not run progressively stronger cycles to remove food from a coating already damaged or unsuitable for the dishwasher.

Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
