Bosch Cooktop Error Child Lock: Child Safety Lock Active

1. SAFETY: No electrical hazard — the child lock prevents zones from activating. The cooktop surface is safe to touch if no prior cooking was done.
2. Locate the lock symbol on your cooktop control panel (typically a padlock or key icon).
3. Press and hold the lock button for 3–5 seconds — the cooktop will typically beep and the lock indicator will turn off.
4. If holding the lock button does not clear it, check your user manual — some models require a two-button combination.
5. Alternatively, disconnect power at the circuit breaker for 30 seconds, then restore — this resets the lock on most models.

Error Child Lock on your Bosch cooktop means: The cooktop child safety lock is engaged. All zone and power controls are disabled to prevent accidental operation. This is not an error — it is an intentional safety feature. The appliance's self-diagnostic system has flagged this condition and may have disabled the affected zone or function to prevent damage or unsafe operation.

The most frequent cause is child lock was deliberately activated by pressing and holding the lock button. Work through the causes and fix steps below in order — starting with the simplest check.

This condition is DIY-safe. No tools are required and the fix typically takes under 10 minutes. Follow all steps in sequence.

Indicator conditions like child lock and demonstration mode are common sources of confusion because they cause the cooktop to appear completely unresponsive. They are never a sign of hardware failure — the fix is always a button sequence or power reset.

Bosch oven warnings like this often appear after interrupted heating, control resets, sensor mismatch, or a fault that returns during warm-up rather than during a stable cook cycle.

• Assuming the display code proves one exact failed part before the safe first checks are done.
• Replacing a lock or latch too early when alignment, trapped laundry, or startup conditions may still explain the warning.
• Restarting the appliance repeatedly instead of confirming whether the same fault returns after one clean recovery attempt.

• Child lock was deliberately activated by pressing and holding the lock button
• Child lock was activated accidentally — a common occurrence in households with young children
• Some models auto-activate the child lock after a power cycle

• Do not assume the cooktop is broken when the child lock is active — controls will not respond until the lock is released

Child lock cannot be deactivated by button sequence or power reset — board or control panel fault suspected

• Note your model's specific lock/unlock button sequence in the user manual so you can quickly deactivate the lock when needed

Use the code page for one careful first pass, then stop if the same warning returns or the appliance still cannot get back to normal operation.
