Child Lock

What Your Machine Is Actually Telling You
CL is a feature, not a malfunction. The child lock (Kindersicherung in German, as Bosch originally designed this in Germany) disables all controls except the power button. Its purpose is to prevent curious children from stopping cycles, opening doors, or changing settings.
How it works internally: The control board's firmware ignores all button press inputs when CL is active. The door lock remains engaged. The only input the board still responds to is the specific deactivation key combination — ensuring someone who knows the procedure can always regain control.
Two types of child lock on Bosch washers:
1. Control panel lock — disables all buttons. The cycle continues running normally, you just can't change anything.
2. Full lock (some newer models) — also locks out the power button and the detergent drawer, providing complete protection.
Why CL activates unexpectedly:
1. Accidental activation (80%) — someone pressed the lock combination without realizing it. On many models, it's a 3-second press of a specific button.
2. Children actually did it (15%) — kids experimenting with buttons are surprisingly good at finding the right combination.
3. Board glitch (5%) — very rare, but a transient event can latch CL mode.
The most common panic moment: People see CL and immediately assume their washer is broken. They search for error codes, call technicians, or even consider replacement — when the fix takes 5 seconds.

What You're Probably Seeing Right Now
- The display shows CL and no buttons respond when pressed.
- The machine may be mid-cycle and running normally — you just can't interact with it.
- You may have tried pressing every button with no response — CL blocks them all.
- The machine is idle and won't start — pressing Start does nothing because CL is active.
- A key icon or lock symbol may be illuminated on the display panel.
DIY Fix — From Easiest to Hardest
1
Deactivate Using the Standard Method (5 seconds)
**Works on most Bosch models:**
1. Press and hold the **Start/Pause** button for **3-5 seconds** until CL disappears and the key/lock icon turns off.
2. That's it. The machine is unlocked.
**If Start/Pause doesn't work, try:**
- Some Bosch models use a **combination of two buttons** held simultaneously for 3-5 seconds.
- Common combinations: **Spin + Pre-wash**, **Temperature + RPM**, or **Delay Start + Stain**.
- Check your **model's control panel** — the child lock buttons are usually marked with a small lock icon or the word CL near them.

Check Your Model's Specific Method (2 minutes)
Bosch has several model generations with different CL procedures:
**Series 4/6/8 (current models):**
- Press and hold **Start/Pause** for 3 seconds.
**Older Maxx/Avantixx models:**
- Press **Spin RPM + Temperature** simultaneously for 3 seconds.
**i-DOS models:**
- Press and hold the button next to the **key icon** for 5 seconds.
**Can't figure it out?** Find your **model number** (on the door frame or back panel — starts with WAT, WAN, WAW, etc.) and search for "[model number] child lock" online.

Power Cycle if Button Method Doesn't Work (2 minutes)
If no button combination works:
1. Turn the machine off with the power button.
2. **Unplug** from the wall.
3. Wait **5 minutes.**
4. Plug back in and turn on.
5. Try deactivating CL before starting any cycle.
**Note:** On most Bosch models, CL **survives power cycles** — it's stored in non-volatile memory. But a full unplug can sometimes reset a glitched CL.

Use the Program Selector Dial (1 minute)
If the display is responding to dial turns:
1. Turn the dial to **Off/Reset position.**
2. Then turn to any program.
3. Try the CL deactivation button combination again.
**Some models require:** Turning the selector to a specific position before CL can be disabled.

5
Factory Reset (5 minutes — If CL is Stuck Due to Board Glitch)
This resets all settings including child lock:
1. Turn the program dial to **Off.**
2. Press and hold the **Spin** button.
3. While holding Spin, turn the dial to **position 8** (or the Cotton 60°C position — varies by model).
4. Release Spin.
5. The display should flash briefly — confirming reset.
6. Turn dial back to Off, then select a program.
**Note:** Factory reset also clears any custom preferred settings. You'll need to re-set your preferences.
**If this doesn't work for your model:** Consult the user manual for the specific reset procedure, as Bosch has different procedures for different model years.
1. Turn the program dial to **Off.**

Prevent Future Accidental Activation
If you don't have children and don't need CL:
**For future prevention:**
- Learn which buttons activate CL on your model so you can avoid them.
- Most activations happen when pressing buttons while cleaning the control panel or when reaching across the machine.
**If you have children:** CL is actually valuable — just make sure all adults in the household know the deactivation method. Write it on a small label stuck inside the detergent drawer.

When to Call a Pro
- •CL won't deactivate after all methods including factory reset — the control panel PCB may have a stuck button or firmware corruption. Technician: $80-$150.
- •CL activates on its own repeatedly — a button on the panel is malfunctioning (stuck, water damage, cracked ribbon cable). Control panel repair: $100-$250.
- •Display shows CL but buttons have no icon/label — you may need the user manual for your specific model's procedure. Download free from bosch-home.com.
