Only where the cooker instructions permit it. Cast, enamelled and coated supports can have different cleaning restrictions despite similar appearance.
What the observation means
Detergent, prolonged moisture and mechanical contact may affect a finish or leave the part unsuitable for immediate refitting. The supports must return to their designated positions.
A useful next step
Follow the manual's cleaning and drying method while everything is cool. Check for damage without bending or grinding the support. If a pan no longer sits securely, leave the position unused and obtain compatible advice rather than adding foil pads or adhesive feet.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
