What Does Error E115 Mean?
The Bosch oven E115 error indicates an over-temperature condition, typically due to a malfunctioning temperature sensor or issues with the control board. This error can manifest during the heating process or the self-cleaning cycle, causing the oven to stop heating and potentially lock the door until the temperature decreases. If you encounter this error, it is crucial to address the underlying issue to ensure safe and effective operation.
Common Symptoms:
- Error appears when oven temperature exceeds allowable safe range during heating or self‑clean cycle
- Oven may stop heating and door can lock until temperature falls
- Error may appear during or after pyrolytic self‑cleaning
Possible Causes
- Over‑temperature safety trigger due to excessive internal heat (medium)
- Faulty or inaccurate temperature sensor (medium)
- Control board (relay or regulation) malfunction affecting temperature control (medium)
How to Fix Error E115
DIY Fix Immediate Cooling and Power Reset
- Turn off the oven immediately and allow it to cool completely
- Disconnect power by unplugging or switching off the circuit breaker for about 10 minutes
- Reconnect and restart the oven to see if the code clears
Technician Only Inspect and Replace Temperature Sensor or Control Components
- Test the oven temperature sensor resistance with a multimeter and compare to expected value
- Inspect wiring harness between sensor and control board for damage or loose connections
- If sensor is faulty, replace it; if readings and wiring are correct, evaluate the control board and relay components for faults
Parts needed: Temperature sensor, Control board / relay module, Wiring harness
- If the error persists after basic power reset and cooling
- If the oven overheats repeatedly or shows inconsistent temperature behavior
- If internal components like sensor or wiring appear damaged
