Check the item's complete instructions. Some products specify a rack position, maximum treatment or other restriction rather than unrestricted use in every cycle.
Understanding this situation
The appliance may offer intensive, sanitising or machine-care modes that are not equivalent to an ordinary dish load. A suitable material can still be damaged by an incompatible programme or chemical product.
A useful next step
Match the item requirements to the programme table. Do not use the strongest cycle by default simply because a dishwasher symbol is present. Retain the instructions if an unexpected finish change occurs.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
