VERIFIED
Bosch oven E204 is associated with cavity 2 temperature sensor short circuit. Review symptoms, model details, and safe external checks before deciding on the next step.
If E204 appears on a Bosch oven, the verified technical anchor is cavity 2 temperature sensor short circuit. Similar Bosch product generations can differ internally, so preserve the model number and symptom sequence before resetting anything.
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

What the control is reporting
The verified technical anchor for E204 is cavity 2 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 can happen while the code is active
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 can become inconsistent.
- The appliance might stop a program as a protective response.
- The same code may reappear immediately after startup.
What may be causing it
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.
What you can verify externally
- 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.
When continued operation is not appropriate
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.
When external checks are no longer enough
The sensor, wiring, connector path, and control input must be tested against the documentation for the exact model before a part is selected. A displayed code is evidence, not a parts order. The next step is to confirm the reported system against the model and the symptoms present during operation.
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 E204 with the correct technical documentation and related parts.
FAQ
For this record, E204 is associated with cavity 2 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 E204 display, the cycle stage or operating state where it appears, the visible symptoms, and the external checks already completed.
Bosch service in the San Francisco area
Need model-specific diagnosis for E204?
If E204 remains active or comes back, request Bosch oven diagnosis for the San Francisco service area. Include the complete model/E-Nr, exact code, symptom summary, and ZIP code so service coverage can be confirmed.
Model compatibility: Bosch reuses codes across series and model years, so E204 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
