How to interpret the display
The verified technical anchor for F91 is maximum oven-door unlock attempts exceeded. Preserve that meaning in the factual layer. The warning narrows the diagnostic path toward the door, latch, or locking circuit, while the exact model and symptom sequence determine how that information should be applied.
Operating behavior that adds context
Before changing settings or cycling power, record the behavior you can see or hear:
- The appliance may refuse to start.
- A cycle can stop unexpectedly.
- The door might remain locked or fail to lock.
- The control may not recognize the expected door position.
Where diagnosis may need to look
The source record supports considering the following possibilities without treating any single one as confirmed:
- The door not reaching its expected position.
- A damaged latch, hook, or lock mechanism.
- A door sensor or switch fault.
- Wiring or electronic control failure in the interlock path.
Safe owner-level checks
- Confirm clothing, cookware, or another object is not preventing normal closure.
- Look over the visible latch area for obvious debris or physical damage.
- Avoid force a locked door and do not bypass the interlock.
These checks are for information gathering only. Do not expose live wiring, bypass an interlock, defeat leak protection, open a sealed refrigeration circuit, or use undocumented service-mode procedures.
Safety stop conditions
Do not continue operating an appliance with a door that cannot latch securely or with a defeated safety interlock.
What a service visit needs to determine
A returning door code with normal external alignment requires testing of the lock/switch, wiring, and model-specific control path. The useful service history includes when the code appears, whether it is repeatable, and what changed immediately before it.
For a service request, include what the appliance was doing immediately before the warning and which safe checks were already completed.

FAQ
For this record, F91 is associated with maximum oven-door unlock attempts exceeded. The exact model/E-Nr still matters because Bosch can use different hardware and diagnostic logic across product families.
Only if no safety stop condition is present and the appliance is otherwise operating safely. If the warning repeats, performance is abnormal, or there is leaking, smoke, electrical odor, sparking, overheating, or repeated breaker trips, leave the appliance off.
Use only a normal reset that Bosch documents for the exact model. If the warning returns, repeated resets are not a substitute for diagnosis.
No. The code identifies a detected system condition. Model information, symptoms, and model-specific testing are still needed before a component is selected.
Have the full Bosch model/E-Nr, the exact F91 display, the cycle stage or operating state where it appears, the visible symptoms, and the external checks already completed.
