VERIFIED
Bosch range ER22 is associated with electric-cooktop keyboard fault. Review symptoms, model details, and safe external checks before deciding on the next step.
A Bosch range showing ER22 has detected a condition tied to electric-cooktop keyboard fault. The code helps identify the system involved; it does not by itself prove which component has failed.
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.

Technical meaning of the code
The verified technical anchor for ER22 is electric-cooktop keyboard fault. 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 you may notice
Before changing settings or cycling power, note the behavior you can see or hear:
- Controls may be unresponsive or inconsistent.
- The appliance can stop before completing the selected function.
- A code may reappear immediately after startup.
- One feature may fail while others remain available.
Systems and conditions to consider
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.
Checks to make before service
- 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.
Leave the appliance off if
Stop immediately for smoke, burning odor, sparking, visible electrical damage, or repeated breaker trips.
If the warning returns
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
Use the exact Bosch model number when booking. It is the safest way to connect ER22 with the correct technical documentation and related parts.
FAQ
For this record, ER22 is associated with electric-cooktop keyboard fault. 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 ER22 display, the cycle stage or operating state where it appears, the visible symptoms, and the external checks already completed.
