The short answer
F4 on this cooktop means the published remedy is to make sure the pot or pan is centred on the surface cooking area and that nothing hot is on the touch control panel — that is what the manufacturer published for it, and no more. The cooktop is usable as soon as the pan is centred and the control panel is clear. One of the checks below is an owner check, and the rest of the work is behind a panel.

What the machine does alongside the code
- The panel misbehaves while a hot pan or lid sits near it — That is the second half of the published remedy, and it is easy to miss.
- 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.
What triggers F4, most likely first
- A pan off centre on the zone — It goes first because the published remedy names it first: the zone marking is the detection area, and a pan overhanging it is partly invisible to the appliance.
- A warped, ridged or uneven base — A base that rocks or bows leaves an air gap, and the zone loses detection intermittently rather than outright, which is why the fault seems random.
- 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.
Check in this order, and why
- Clear anything hot off the control panel — A lid, a trivet or a pan edge over the control area is exactly what the remedy warns against.
- Try a different pan on the same zone — The other half of the same test, and between them the two answer the question completely.
- Check the base against what the manual accepts — Material and diameter both matter, and the manual for your model line is the authority.
The reset, then the owner-safe checks
- Test the suspect pan on every zone in turn — Write down which zones accept it. A pan rejected everywhere is the answer; a pan rejected on one zone is not.
About 15 min
- Centre the pan on the marking, take everything off the control panel and select the zone again — Both halves of the published remedy at once, because either alone can produce the reading.
About 5 min
- Clean the zone surface and the pan base — Burnt-on residue between the two acts as the air gap that breaks detection.
Tools: cloth, mild detergentAbout 10 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 anything is opened
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.
When this is a service call rather than a reset
Call if the zone cuts out under a pan it previously accepted, or if the glass above it is cracked or discoloured.

What this page does not cover
This reading applies to the KitchenAid cooktop line as a whole, not to one family or model. It does not cover what differs between model lines — wiring colours, connector positions, part numbers and service-mode sequences — which are in your own model manual and which a technician matches to the rating plate rather than to this code. Where a family- or model-specific page for this code exists, it is linked from the code index below and it is the more specific answer.
