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.
-
One burner or all of them Gas burner will not light
Igniters clicking without catching, a burner that lights and goes out, or a flame that has turned yellow. Whether it is one burner or every burner is the fastest diagnostic on this site.
- Clicks but does not catch
- Lights, then goes out when released
- A yellow or lifting flame

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 gas ignition error code F2
What this one means
The electronics have overheated and the automatic ignition has stopped working with them.
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:
- F2, F4 or F5 with the automatic ignition not working — how a model with no digital display says it. On that machine, the lights are the code
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 ignition electronics
- Heat reaching them from the burners above
What to try yourself
- Turn all burners off, or use the lowest setting, until the electronics cool
- Check whether the burners have been running high for a long stretch
Then what
The gas version of the overheat protection: the appliance keeps the gas usable and gives up the automatic ignition first. A cooktop that does this regularly is telling you something about its ventilation.
This code is published for cooktops & rangetops and ranges. The full list of codes has the rest.
