The reading in two sentences
Read C82 as this: the pan or pot is not the right size for the zone. Every other zone is unaffected, and the zone itself works as soon as a pan it can detect is on it. You can settle whether this is a one-off or a real fault yourself; naming the failed part is not owner work.

| C82 | Pan/pot is not the right size. |
What else is happening when this shows
- The zone works as soon as a larger pan goes on it — Which settles the question in one move.
- The code follows a particular pan around the hob — That is the clearest evidence there is that the pan and not the appliance is being reported.
- The zone works with a different pan — Swapping the pan is the whole test, and it takes a moment.
What triggers C82, most likely first
- A base too small for the zone — It goes first because the published meaning names it: detection needs enough base over the coil, and a small pan on a large zone is invisible to it.
- A pan overhanging the zone marking — A pan pushed to the edge has its base partly off the coil, which is the same problem seen from the other side and is fixed by centring it.
- A genuine fault in the zone or its detection circuit — Last, and only after the pan has been changed: if a known-good pan on the marking still fails on that zone alone, the appliance is the remaining candidate.
The order to work through
- Try the same pan on a larger or smaller zone — If it works on one and not the other, size is the whole answer.
- Compare the pan base against the zone marking on the glass — The marking is the detection area, not a decoration.
- Try the same pan on a different zone — If the fault follows the pan, you are finished: the appliance is behaving correctly.
- Body: Start with position and cleanliness, because both are free and both break detection in exactly the way the code describes.
The reset and the checks that follow it
- Swap in a pan you know the appliance accepts — One swap on one zone is the entire diagnosis for most of these codes.
About 5 min
- Match the pan to the zone marking and centre it, then select the zone again — Use the smallest zone for a small pan rather than the nearest one.
About 5 min
- Centre the pan on the zone marking and retry — Square on the marking, not near it. Then select the zone again from cold.
About 2 min
- STOP HERE if one zone rejects every pan — That points inside the appliance, where the coil and its detection circuit are service items.
Before a panel comes off
Safety
Isolate the cooktop at its circuit breaker before any panel comes off — a capacitor can hold a charge after the power is off, and this is a fixed high-current appliance rather than one you unplug. Put nothing cold or wet on hot glass. On a gas model, if you smell gas, leave the building and call the gas utility from outside.
Where an owner check ends
Call if the zone cuts out under a pan it previously accepted, or if the glass above it is cracked or discoloured.

What is deliberately not here
Treat this as the general KitchenAid cooktop reading. It stops short of anything model-specific — part numbers, harness colours, connector layouts and service-mode entry — because those differ by family and a technician takes them from the rating plate rather than from a code. A family- or model-specific page, where one exists, is linked from the code index below and is the closer answer.
