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 protection working Cooktop zone switching itself off
A zone that cuts out under load, or a cooktop that shuts down after a while at high power. Almost every version of this is a protection doing its job, and each one has a published code that says which.
- Cuts out after twenty minutes on high
- All zones off at once
- Comes back after it cools

What else belongs to the cooktops & rangetops
On this make a code belongs to the appliance rather than to a product line. These are the other conditions this machine can display, and the models that can show this one — a display often has more than one thing to say, and the model number decides what any of it costs to put right.

About Bosch error code F1
What this one means
The cooking zone got hot enough to threaten the work surface and switched itself off.
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:
- The zone's own temperature protection
What to try yourself
- Wait for it to cool, then switch the zone back on and carry on cooking
- Note whether it happens on one particular zone every time
Then what
Protection, not a failure. If one zone does this repeatedly and the others never do, that zone's sensing is worth looking at — but the appliance is behaving correctly either way.
This code is published for cooktops & rangetops and ranges. The full list of codes has the rest.
