Check the specific part's care instructions before using a dishwasher. Plastic drawers, trims and glass assemblies can have different heat and detergent tolerances.
What the observation tells you
A part surviving one wash does not show that repeated washing is suitable. Warping may first appear as a drawer that catches or a shelf trim that no longer fits properly. That later symptom can easily be mistaken for movement of the cabinet itself.
A useful next step
Use the manufacturer-approved cleaning method and allow parts to dry before refitting. If a fitting has changed shape, do not force it into its supports. Give the model and affected component when asking about a replacement, since similar-looking fittings may differ.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
