What we can confirm
Code C0, from the manufacturer's own documentation
A code is only meaningful together with the machine showing it — the same digits mean different things on different equipment.
The code
C0
The sensor under the glass that watches surface temperature has gone out of circuit. Induction surfaces depend on that reading to protect both the glass and the electronics beneath it, so the cooktop will restrict itself rather than run blind. It is a component problem rather than a sign that the surface is finished, and on these cooktops the sensor and its lead sit under the glass but are reachable without replacing the panel.

What else belongs to the cooktops and rangetops
On this make a code belongs to the appliance rather than to a product line. These are the other conditions this machine can display, and the models that can show this one — a display often has more than one thing to say, and the model number decides what any of it costs to put right.
Other codes this appliance can display
Top sensor short.
IGBT sensor open.
Communication failure between the main and sub PCB.
Communication failure with the EEPROM.
Communication failure with the touch-enabled IC.
Fan motor malfunction — a blocked DC motor, or a problem in the board or wiring.
Input voltage too high or too low — outside the 208 to 240 volt range.
A key was pressed or held for more than eight seconds — a wet or stuck keypad.

About Cooktop error code C0
What C0 means on this make
The sensor under the glass that watches surface temperature has gone out of circuit. Induction surfaces depend on that reading to protect both the glass and the electronics beneath it, so the cooktop will restrict itself rather than run blind. It is a component problem rather than a sign that the surface is finished, and on these cooktops the sensor and its lead sit under the glass but are reachable without replacing the panel.
Where this appears, and which table it belongs to
On the appliance's own display. Photograph it before you cut the power: a display that has been cleared has taken the evidence with it, and there is no way to ask the machine for it again. Then check the model, because this make changed hands in 2016 and the two generations share no code string. The same characters mean different things on a Classic ERC oven, an ER-series range and a Modernist induction cooktop, and a meaning read off the wrong table is worse than no meaning at all.
Which machines this one applies to
Modernist induction cooktops. The same number on a different appliance of this make is a different page and often a different repair, which is why this archive is organized by appliance rather than by number. This maker documents codes on 5 of the appliance types this site publishes — coffee machine, cooktop, dishwasher, oven and range — and publishes none at all for freezer, microwave, range hood, refrigerator and wine cooler. Those appliances have symptom pages here and no code pages, which is the honest answer rather than borrowing a table from the machine next door.
What to do about it
- Note which zone or zones are affected — a single zone narrows it considerably.
- Cut power at the breaker for a minute; a one-off reading error sometimes does not return.
- The sensor circuit is measured rather than the sensor swapped on suspicion.
- This does not usually mean new glass, and a quote that starts there deserves a question.
Where this goes next
The job this usually becomes is induction cooktop repair, and that page 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, reminders and settings rather than problems — the visit ends there and you pay the diagnostic and nothing else, or call (305) 363-6067 and describe what the panel is doing before booking anything.
