These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.

Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.
Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Cancel Self Clean
- Who:
- you.
- How:
- cancel the Self Clean function from the panel, as Bosch instructs. Do not force the door.
- Result that matters:
- the oven accepting the cancel and starting to cool down.
- If it cancels normally:
- wait for the unlock before going on.
- If the panel does not respond:
- switch the oven off at the circuit breaker and call Bosch service.
- Evidence to keep:
- a note of when in the cycle e126 appeared.

Wait for the unlock and restart
- Who:
- you.
- How:
- wait until the door unlocks by itself and start Self Clean again, as Bosch instructs.
- Result that matters:
- whether the full cycle finishes without e126.
- If it finishes:
- the fault was a one off in that cycle.
- If e126 returns:
- it points to a lock fault and Bosch service is next.
- Evidence to keep:
- a photo of the code and the time it appeared on each attempt.

Call Bosch service
- Who:
- you.
- How:
- if it persists, do not keep repeating Self Clean; note the model and code and contact Bosch for a visit.
- Result that matters:
- the technician knowing the fault repeats after the manufacturer steps.
- If the door stays locked with the oven cold:
- say so when calling.
- If the oven works in normal modes:
- note it, it helps narrow the fault to the lock.
- Evidence to keep:
- your notes from each attempt.

What it means
For the freestanding ranges Bosch documents on its US site, e126 means the door lock on the appliance is malfunctioning. The lock works mainly during Self Clean, when the oven reaches very high temperatures and must keep the door from opening. Bosch asks you to cancel the cleaning, wait for the door to unlock and start again, which shows an interrupted cycle can be enough to trigger it. The code alone does not prove the lock mechanism is faulty.
