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.

- 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](https://thermadormiami.support/error-codes/) has the rest of them, searchable, including the labels older and newer machines use for the same conditions.
