Bosch oven E115 error code
E115 means over-temperature detected. The electronics recorded a cavity temperature above the safe limit — often after a faulty thermostat or blocked cooling..
Engineer usually needed · Fault type: Electrical/hardware
Safe checks, in order of likelihood
- Let the oven cool fully, then power-cycle at the mains.
- Run a low program and see whether E115 returns.
- Check the cooling fan (if fitted) runs and its vents are clear.
Call a professional when…
Reset; then the thermostat, sensor and cooling are tested by an engineer. If the code returns after these checks, book a qualified engineer.
Parts usually involved
- Bosch oven thermostat / sensor as required.
