Bosch Oven Error Code E215

E215 means that the temperature in the second oven cavity exceeded the allowable limit while the door was unlocked. In response, the oven stops heating that cavity and locks the door automatically. The error clears and the door unlocks once the cavity cools to an acceptable temperature. However, the underlying cause must be identified and corrected to prevent the fault from returning.

You should not continue using the oven until the cause of the overheating has been diagnosed and repaired. The E215 code indicates a real thermal event in Cavity 2, not just a sensor glitch. Continued use without repair could result in repeated overheating, damage to the appliance, or a potential safety hazard. Wait for the oven to fully cool and have a qualified technician inspect it before operating it again.

Repair costs depend on which component has failed. A replacement temperature sensor typically runs in the range of $20 to $80 for the part. A heating element for a Bosch oven usually falls in the $50 to $150 range. Control board replacement is the most expensive repair, with parts often ranging from $150 to $400 or more, plus labor. Having a technician diagnose the specific failed component first can help avoid replacing parts unnecessarily.

The E215 error is designed to clear on its own once Cavity 2 cools back to an acceptable temperature range, at which point the door also unlocks automatically. A manual reset may temporarily clear the code, but if the root cause such as a stuck relay, bad temperature sensor, or failing element is not repaired, the fault will return during the next use. Resetting without diagnosing the cause is not a reliable fix.

Fixing E215 requires identifying which component caused the over-temperature condition. Start by checking that the heating element in Cavity 2 is functioning correctly and not shorted. Then test the temperature sensor resistance to confirm it is reading accurately. Inspect the control board for stuck or welded relays. If none of those components are the cause, replacing the control module is the next step.
