Cooktop surface around gas burners becomes discolored or enamel peels.

User steps:

• Check that burner caps are correctly seated and not tilted.
• Use pans that match the burner size; avoid very large pans that overhang excessively.
• Do not operate burners without cookware for extended periods.

Technical steps (gas technician):

• Verify correct injector size and gas type configuration.
• Adjust flame height to manufacturer specifications.
• Replace severely damaged enamel pan supports or cooktop surface parts if necessary.
