Bosch HBE5452UC is a U.S.-market 500 Series 24-inch built-in wall oven with a 2.5 cu. ft. cavity. The matching Bosch manual describes electronic controls, touch-selection areas and a rotary selector. If the screen displays a D- or E-prefixed message, record every character before doing anything else. Bosch illustrates examples but does not give separate component diagnoses for those examples. Check the oven's visible settings and ordinary household power first. Stop using the appliance if the wiring smells hot, the door or glass is damaged, or the oven fails to respond safely.

No manufacturer-confirmed error symbols are currently recorded for this exact model. This does not prove that the appliance cannot display a code or warning.

The directory currently provides no verified error-code table for this model. Check the official model manual and symptom advice; do not apply generic codes from another appliance.
What to check when no error symbol is clear
- Display message: Copy the full D- or E-prefixed message. Bosch shows D0111 and E0111 as examples only; do not infer what individual parts have failed.
- No heat: Check whether the oven is in demo mode. The manual associates a lit m symbol with this mode and provides the controlled deactivation method.
- Power interruption: The manual may request language and clock settings again. This is not, by itself, proof of a failed component.
Controls and normal operating indications
Display, touch fields and rotary selector described in HBE5452UC manual. Heating modes and settings as listed in the HBE5452UC use and care manual. Use the actual display text and the serial-number variant on the rating plate when comparing any online instructions.
Reset and recurrence
For a D- or E-prefixed message, Bosch says use the On/Off button to switch the oven off and on once. If the message returns, quote it to Bosch service (manual p. 29). Do not keep cycling power to bypass a recurrent malfunction. Contact Bosch-authorized service for persistent failures.

Official sources and evidence limits
The manufacturer manual describes a display, touch selection fields and a rotary selector; D/E-prefixed error-message examples are given without individual component diagnoses. No source-verified individual fault-code meaning is being claimed for this model. If a symbol appears, copy it exactly and use the matching E-Nr manual or Bosch service; a generic brand list does not establish applicability.
When professional service is necessary
Stop use for damage, burning odors, failed shutoff, unsafe door operation or repeat faults after the authorized external checks. Do not mistake the example D0111/E0111 strings for a verified model-specific code list. Have the model E-Nr, FD/serial identifier and exact observed symptom available for Bosch service.
