VERIFIED
Bosch oven E104 is associated with cavity 1 temperature sensor short circuit. Review symptoms, model details, and safe external checks before deciding on the next step.
A Bosch oven showing E104 has detected a condition tied to cavity 1 temperature sensor short circuit. The code helps identify the system involved; it does not by itself prove which component has failed.
Start with external observations and documented owner-level checks only. If the warning persists, move to model-specific diagnosis rather than repeated resets or speculative part replacement.
At a glance
- Code: E104
- Appliance: Bosch Oven
- Verified meaning: cavity 1 temperature sensor short circuit
- Primary diagnostic direction: the heating and temperature-control system
- Service-area context: San Francisco; confirm coverage by ZIP code
Technical meaning of the code
The verified technical anchor for E104 is cavity 1 temperature sensor short circuit. Preserve that meaning in the factual layer. The warning points the diagnostic path toward the heating and temperature-control system, while the exact model and symptom pattern determine how that information should be applied.
What you may notice
Before changing settings or cycling power, note the behavior you can see or hear:
- The control may receive an impossible or missing reading.
- Temperature or cycle behavior might become inconsistent.
- The appliance may stop a program as a protective response.
- The same code can return immediately after startup.
Systems and conditions to consider
The source record supports considering the following possibilities without treating any single one as confirmed:
- A failed sensor or probe.
- Damaged sensor wiring.
- A loose or corroded connector.
- An electronic input fault on the control board.
Checks to make before service
- Write down the full code and model number.
- Verify only external conditions that can affect the reading, such as a properly closed door or unobstructed user-accessible area.
- Avoid probe internal sensor circuits while the appliance is energized.
These checks are intended to gather useful information without exposing live wiring, bypassing an interlock, defeating a leak-protection device, opening a sealed system, or using undocumented service modes.
Leave the appliance off if
Stop for overheating, electrical damage, gas odor, or water near electrical parts; otherwise avoid repeated operation if the sensor is required for safe temperature control.
If the warning returns
The sensor, wiring, connector path, and control input must be tested against the documentation for the exact model before a part is selected. Do not choose the most expensive module from the code alone. The technician should verify the relevant circuit or mechanism before recommending a repair.
For a service request, include what the appliance was doing immediately before the warning and which external checks were already completed.
Why the full Bosch model/E-Nr matters
Use the exact Bosch model number when booking. It is the safest way to connect E104 with the correct technical documentation and related parts.
FAQ
For this record, E104 is associated with cavity 1 temperature sensor short circuit. 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 code 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 E104 display, the cycle stage or operating state where it appears, the visible symptoms, and the external checks already completed.
