VERIFIED
Bosch range E009 is associated with rOM-check fault in the user interface. Review symptoms, model details, and safe external checks before deciding on the next step.
If E009 appears on a Bosch range, the verified technical anchor is rOM-check fault in the user interface. Similar Bosch product generations can differ internally, so preserve the model number and symptom sequence before resetting anything.
Treat the warning as evidence, not a complete repair instruction. Keep the troubleshooting boundary outside protected systems and do not bypass safety devices to clear a code.
At a glance

What the control is reporting
The verified technical anchor for E009 is rOM-check fault in the user interface. Preserve that meaning in the factual layer. The warning points the diagnostic path toward the electronic control path, 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:
- Controls might be unresponsive or inconsistent.
- The appliance may halt before completing the selected function.
- A code may reappear immediately after startup.
- One feature may fail while others remain available.
What may be causing it
The source record supports considering the following possibilities without treating any single one as confirmed:
- A fault within the control-board electronics.
- Memory or configuration data outside the expected state.
- A relay or electronic switching fault.
- Wiring, supply, or a connected load affecting the control.
What you can verify externally
- Write down the exact display and full model number.
- Keep the control surface clean and dry where touch controls are involved.
- Follow one normal manufacturer-approved power reset when there is no sign of electrical damage.
- Avoid replace a control board from the code alone.
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 immediately for smoke, burning odor, sparking, visible electrical damage, or repeated breaker trips.
When external checks are no longer enough
If the warning comes back, the control board, connected loads, wiring, supply, and configuration need platform-specific testing. 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 external checks were already completed.
Why the full Bosch model/E-Nr matters
Bosch can reuse similar display characters across different range generations. Confirm the full model/E-Nr before applying platform-specific repair information.
FAQ
For this record, E009 is associated with rOM-check fault in the user interface. 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 E009 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 E009?
If E009 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 E009 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
