- Switch the oven off, allow it to cool if needed, and isolate power for 60 seconds.
- Check whether the roasting thermometer plug is seated correctly and the cable is undamaged.
- Restore power and check whether F111 clears. If it does not, move to the deeper checks below.
Indicates the roasting thermometer is faulty or not connected properly. On the AEG BPK742L81M, a persistent F111 usually means the related component, connection, or control path needs further diagnosis.
- F111 appears on the display and normal oven operation is interrupted.
- The oven may refuse to start, stop mid-cycle, or disable a specific feature linked to the fault.
- The fault may return straight after a reset if the underlying issue is still present.
- That the roasting thermometer is faulty or not connected properly.
- Loose connection, sensor issue, or component fault in the affected circuit.
- Temporary software or control-board glitch if the code appeared once after a power interruption.
- Note exactly when the code appears: at startup, during preheat, when using a probe, or when trying a connected feature.
- Remove accessories that might be connected to the fault, such as a roasting thermometer or network setup step, and test again if that is safe.
- Record the model, code, and any recent power cuts or software updates before contacting support.
| Checkpoint | What to confirm | Good result | If it fails |
|---|---|---|---|
| Reset | Oven isolated for 60 seconds and restarted | Code clears | Move to targeted checks |
| Related feature | Affected part or feature checked safely | Oven works normally | Book service if fault returns |
| Repeat fault | Code stays away on retest | Likely temporary glitch | Persistent fault needs diagnosis |
- Assuming the code has cleared permanently after one reset without retesting the affected feature.
- Continuing to use the oven while the same code keeps coming back.
- Attempting internal electrical repairs without training.
- Do not dismantle oven panels or wiring unless you are qualified.
- Do not force sensors, probes, or connectors if they do not fit easily.
- Let the oven cool fully before checking lights, probes, or interior fittings.
- Isolate mains power before any inspection beyond simple user-accessible parts.
Contact AEG support or book service if F111 returns after the safe checks, or immediately if the affected component cannot be checked safely at home.
- Avoid pulling on cables, probes, or light fittings during cleaning.
- Keep connectors, lamps, and accessories fitted exactly as described in the user manual.
- Document unusual faults early instead of waiting for the oven to fail completely.
