VERIFIED
Bosch range E204 is associated with cavity 2 / warming-drawer temperature sensor short circuit. Review symptoms, model details, and safe external checks before deciding on the next step.
When a Bosch range displays E204, the control has registered cavity 2 / warming-drawer temperature sensor short circuit. That narrows attention toward the heating and temperature-control system, but the model/E-Nr and visible symptoms are still necessary before the warning is treated as a parts diagnosis.
The guidance below remains at the owner-safe level. It focuses on recording the condition and checking accessible items without opening protected electrical, water, gas, refrigeration, or mechanical systems.
At a glance
- Code: E204
- Appliance: Bosch Range
- Verified meaning: cavity 2 / warming-drawer temperature sensor short circuit
- Primary diagnostic direction: the heating and temperature-control system
- Service-area context: San Francisco; confirm coverage by ZIP code
What the warning means
The verified technical anchor for E204 is cavity 2 / warming-drawer 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.
Symptoms worth recording
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.
Possible causes
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.
First steps that stay outside the appliance
- 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 to stop using the appliance
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 diagnosis becomes the next step
The sensor, wiring, connector path, and control input must be tested against the documentation for the exact model before a part is selected. If the warning is intermittent, note the program, temperature, load, or operating stage that makes it return. That pattern can narrow diagnosis considerably.
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
Have the complete model/E-Nr with E204. That identifier helps separate platforms that may use different controls, sensors, or service logic.
FAQ
For this record, E204 is associated with cavity 2 / warming-drawer 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
Still seeing E204 on your Bosch range?
If E204 remains active or comes back, request Bosch range 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.
