What's Happening

The oven went above its maximum safe temperature. The door locks and the oven shuts off. This can happen during self-clean if the cycle runs too long, or if the cooling fan fails during normal use.

How to Fix It

Wait for the oven to cool completely — this can take 2-4 hours. Don't force the door. If E-13 occurs during normal baking, the thermostat or control board relay may be allowing continuous heating. Have both checked.

Frequently Asked Questions
What does E-13 mean on a Bosch oven?
E-13 means the oven exceeded its maximum safe temperature. The oven locks the door and shuts down until it cools.
How long does it take for a Bosch oven to cool after E-13?
Typically 2-4 hours. The door releases automatically once the oven reaches a safe temperature. Don't try to force it open.
Can a failed cooling fan cause E-13?
Yes. The cooling fan protects the electronics and outer panels. If it fails, heat builds up beyond safe limits even during normal baking.
