--- title: "La Cornue induction hob: scratches in the ceramic glass, and what the maker says can and cannot be undone" description: "La Cornue induction hob: scratches in the ceramic glass, and what the maker says can and cannot be undone: la Cornue — an indicator rather than a code." url: "https://la-cornuemiami.support/error-codes/scratched-hob-glass/" date_modified: "2026-09-04" Appliance type: "Cooktops and rangetops, Ranges" --- # La Cornue induction hob: scratches in the ceramic glass, and what the maker says can and cannot be undone ### What the appliance is actually doing The guide is honest about this one: mineral deposits from water or food can be removed with a cleaning cream, but tiny scratches are not removable — they simply become less visible over time as a result of cleaning. Its advice is preventative rather than curative: use the recommended cleaning methods and make sure pan bottoms are smooth and clean. A rough or gritty pan base dragged across ceramic glass is what causes most of this, and it is worth knowing before the surface is marked rather than afterwards. ### Quoted rather than interpreted > Always use the cleaning methods recommended in this guide, and make sure that the pan bottoms are smooth and clean. From the CornuFé 110 induction installation and user guide (U111136-03, January 2023), in a User Guide & Service Manual downloaded from La Cornue’s own site. Nothing on this page is decoded beyond what that sentence says. ### Which machines this one applies to La Cornue induction cooktops and rangetops, and the electric and multifunction ovens. La Cornue publishes three codes in the whole of its US documentation and its Château guide carries no troubleshooting section, so a behavior missing from this archive is not proof that your appliance cannot do it — the maker simply never wrote a table for it. What its guides do document, they document in sentences, and those are on this site under the maker’s own wording. The model number, and which top the range was ordered with, settle what any of it means. ### What to do about it - Check your pan bases. Rough, pitted or gritty bottoms are what scratch ceramic glass. - Lift pans rather than sliding them, particularly cast iron. - Use the cleaning products the guide recommends and a cleaning cream for mineral deposits. - Accept that fine scratches do not come out. The maker says so plainly and anybody promising otherwise is selling something. - Distinguish a scratch from a crack — a crack is a safety matter and it has its own page. ### Where this goes next The job this usually becomes is [diagnostic visit](/services/diagnostic-visit/), and every one of those pages carries a starting figure and the reasons that move it. If it turns out to be nothing — and on this make a real share of these are modes rather than problems — the visit ends there and you pay the diagnostic and nothing else, or call [(305) 614-3699](tel:+13056143699) and describe what the display is doing before booking anything.
