Bosch documents only one specific oven error code for consumers — E11, a touch key malfunction often caused by condensation on the keypad. Every other “E” followed by a number is treated by Bosch’s own support documentation as a general fault, with the same documented response regardless of the specific number: note the code, reset the oven, and call support if it returns.
Why there is no full code list
As with Bosch refrigerators, Bosch’s official US owner-support page for ovens and microwaves documents only a small number of specific codes and treats the rest as a general fault category. Third-party sites publish longer tables (E01, E30 and similar), but these are not confirmed on Bosch’s own support pages and can vary by control-board revision and model year, so they are not reproduced here as verified fact.
| What Bosch documents | Meaning |
|---|---|
| E11 | The touch keys are not operating properly — often due to condensation on the keypad |
| “E” plus any number | A malfunction has occurred — treated as a general fault |
| “E” plus a number, with beeping | The same general fault, with an audible alert |
E11: Touch key fault
This is the one code Bosch specifically documents. Since condensation on the control panel is a common trigger, wipe the touchpad area dry and fully before testing again — this alone resolves a meaningful share of E11 occurrences, particularly after cleaning the oven or a steam-heavy cooking session.
Any other “E” plus a number
Bosch’s documented guidance treats any other numbered E-code the same way: note the exact code shown (useful for the support call if the reset does not clear it), then proceed to the reset procedure below.
How to reset
- Note the code shown
Even though Bosch does not publish what most codes individually mean, having the exact code ready speeds up a support call if the reset does not resolve it.
- Turn the oven off at the breaker
Rather than just using the control panel’s power function.
- Wait roughly 30 minutes
This is the wait time Bosch’s own guidance specifies before restoring power.
- Restore power and check the display
If the code is gone, run a short test cycle before loading food back in.
When to call for service
Bosch’s own support guidance is to call Bosch Customer Support at 1-800-944-2904 (US) if an error code returns after the breaker reset, rather than attempting further self-diagnosis — reflecting how tightly Bosch controls what consumer-level troubleshooting it recommends for its oven control boards.
