The short answer
F1 on this oven means the cooking zone has overheated and has switched off to protect the work surface — that is what the manufacturer published for it, and no more. The other zones are unaffected; let the surface cool and the zone returns, but a repeat means the heat has nowhere to go. One of the checks below is an owner check, and the rest of the work is behind a panel.

|---|---|
| F1 | The cooking zone has overheated. It has switched off to protect the work surface. |
What the machine does alongside the code
- The surface around the zone is markedly hot to the touch — The code is reporting something true, which is the reason it exists.
- It works again once everything has cooled — That recovery is the signature of a thermal protection rather than a failure.
What triggers F1, most likely first
- A long run at a high setting, often with an empty or oversized pan — It goes first because it is the ordinary cause on healthy hardware: a zone run hard for a long time, or run under a pan that does not take the heat away, puts more into the surface than the design allows.
- A hot ambient or a neighbouring heat source — The appliance is rated for a room, not for an oven alcove; a nearby heat source adds directly to what the internal sensor sees.
Check in this order, and why
- Check the pan and the setting you were using — An empty pan, a pan far larger than the zone or a sustained high setting each explain the trip on their own.
- Check every vent, grille and clearance around the appliance — This is the commonest cause and it is visible from outside.
- Ask what the appliance was doing when it tripped — Long runs, high settings and back-to-back cycles are the ordinary triggers and they change the diagnosis.
The reset, then the owner-safe checks
- Repeat the same use pattern once and watch for the trip — If it trips at the same point, the thermal path is the fault; if it does not, the first trip was a one-off.
About 45 min
- Let the surface cool untouched, clear the vents and the space below, then repeat the same cooking once — Never cool a hot glass surface with anything cold or wet: thermal shock cracks glass.
Tools: vacuumAbout 45 min
- Cut power at the breaker for a minute before the retry — Clears the stored code so that what you see next is live rather than remembered.
About 5 min
- STOP HERE — the cooling fan and the sensor are inside — Both sit behind a panel next to live terminals, which is where an owner check ends.
Before anything is opened
Safety
Unplug the oven or switch off its breaker before any panel comes off — a capacitor can hold a charge after the power is off. The cavity and the glass stay hot long after the heat is off, so let everything cool first. On a gas model, if you smell gas, leave the building and call the gas utility from outside.
When this is a service call rather than a reset
Call at once if the appliance is hot enough to be uncomfortable to touch, if you smell hot plastic, or if it trips cold.

What this page does not cover
This reading applies to the Bosch oven line as a whole, not to one family or model. It does not cover what differs between model lines — wiring colours, connector positions, part numbers and service-mode sequences — which are in your own model manual and which a technician matches to the rating plate rather than to this code. Where a family- or model-specific page for this code exists, it is linked from the code index below and it is the more specific answer.
