The short answer
F0 means something is pressing on the control panel: the manufacturer records an object, liquid or soil putting pressure on the control panel. The cooktop reads a permanent press, cannot tell it from a finger, and stops rather than acting on it.
Error codes
Reference| Code | Meaning |
|---|---|
| F0 | An object, liquids, or soils are putting pressure on the control panel. |
What you observe, and what to record
- The code appears with nothing obviously touching the panel — A thin film of liquid is enough, and it is not easy to see against dark glass.
- How long the ${A} runs before the code appears — Immediately from cold, or well into a session — that interval is the most useful single number you can hand a technician.
- What the appliance was doing at the moment it appeared — Starting, part-way through, or sitting idle. Each points at a different circuit, and it is forgotten within a day if it is not written down.
Causes, most likely first on this cooktop
- Liquid on the panel — First: a boil-over or a wet cloth across the controls is the commonest cause by a wide margin, and water reads as a finger to a capacitive panel.
- An object resting on the control area — Second: a lid, a utensil or a phone left on the glass holds keys indefinitely and looks entirely innocent.
- Dried soil or grease over the keys — Third: a film that built up gradually, which is why the fault can appear with nothing visibly on the panel at all.
Check in this order, and why
- Look along the glass at a low angle — A film shows as a dull patch from the side and is invisible from above.
- Clear everything from the panel area and wipe it dry — The documented remedy, and the whole diagnosis if it works.
- Note whether it returns as soon as cooking produces steam — Steam condensing on the panel is a recurring version of the same cause.
What an owner can safely check
- Remove everything from the control area — Cloths, lids, utensils, packaging. Everything, not just what looks likely.
About 5 min
- Keep a short log of when the code appears — Date, what the cooktop was doing, and how long it had been running. Two entries make a pattern; one does not.
About 5 min
- Wipe the panel with a barely damp cloth, then dry it fully — Dry matters as much as clean — a damp panel behaves exactly like a pressed one.
Tools: microfibre clothAbout 10 min
- Note which functions still work and which do not — Go through them deliberately rather than from memory. The list of what works is the fastest diagnostic information there is.

Safety
Unplug the appliance or switch off its breaker before removing any panel — a capacitor can hold a charge after the power is off. Do not pour water onto hot glass to cool it and do not work on a top that is still warm: thermal shock cracks a ceramic surface, and a cracked top takes the whole appliance out of service.
When to call a technician
Call once the panel is demonstrably clean, dry and clear, the power has been cycled, and the code still appears. That points at a key or the touch module rather than contamination. Everything short of that is a cloth-and-patience problem and does not need anybody paid.

What this page does not cover
This page reads F0 for Jenn-Air cooktops in general, from the manufacturer's shared code index. A code can be documented differently for one family, so where a model-line page exists for your unit it is the more specific answer and is linked below. Not here: wiring colours, connector positions and part numbers, which differ by family.
