The latch that holds the oven door shut is misbehaving. Bosch's remedy runs through Self Clean: cancel it, let the door unlock, run it again.
Model compatibility: Bosch reuses codes across series and model years, so E126 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
e126 is a malfunction of the oven door lock.
The door lock behind e126 is the latch that keeps the oven door closed while Self Clean runs, when the oven interior gets much hotter than during ordinary baking. Everything Bosch lists for this code involves Self Clean, and electric and gas ranges follow the same steps.
Do not force the door
A cancelled Self Clean can leave the oven extremely hot for a long while, and the lock may keep the door shut until it cools.
Tugging on the handle can damage the latch and expose you to the heat inside.
Let the range release the door by itself, and keep children and pets back from the oven front until then.
Clearing the code
Cancel Self Clean.
Give the door time to unlock by itself.
Run Self Clean again.
A second cycle that finishes without e126 needs no follow-up.
If the lock keeps acting up
Bosch says to contact Customer Support or book service when e126 returns during the second Self Clean, or when the door stays locked after a long cool-down. One detail worth passing on during the call: a door that stays latched on an oven that is already cold.

Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
