What it looks like from the kitchen
The symptom this code usually arrives with
A code names the subsystem; the symptom is what sent you to look at the display in the first place. That page says what it usually turns out to be, cheapest cause first.
-
Usually a protection Induction zone switches itself off
A zone that stops mid-cook, or a cooktop that shuts down after a long session at high power. On induction that is nearly always the appliance protecting itself, and it costs nothing to confirm.
- One zone stops during cooking
- Everything shuts down together
- A letter-F code on the display

About Thermador cooktop error code F1
What this one means
One cooking zone has switched itself off to protect the worktop. It is a code the manufacturer publishes for this appliance, not one we have worked out — and it is decoded here rather than left as three characters on a display.
The other ways your machine may say it
The same condition is published under more than one label, because it has been carried across generations of this appliance:
- F1, F6 — the same condition, on machines of different ages
What the code covers
A published cause names a circuit rather than a component, which is the single most useful thing to know before ordering a part. This one covers:
- An empty pan left on heat
- A pan with a warped base
- A zone run at full power for a long time
What to try yourself
- Take the pan off and let the zone cool, then switch it on again
Then what
It is the glass being protected rather than the electronics. If it happens on a normal pan at normal heat, the zone's own sensor is suspect.
This code is published for cooktops & rangetops and professional ranges. The full list of codes has the rest of them, searchable, including the labels older and newer machines use for the same conditions.
