What Does CL Mean on a Bosch Washing Machine?
Press and hold the Start button for five seconds until CL disappears from the display — the machine will return to normal operation immediately (takes about 30 seconds).
Fault description
CL is not a fault code. It stands for Child Lock, a built-in safety feature on Bosch washing machines designed to prevent accidental changes to a running programme — particularly useful in households with young children. When child lock is active, the control panel is effectively frozen: buttons will not respond and you cannot adjust settings or cancel a cycle.
The display will show CL either on its own or alongside the current programme status. The machine itself continues to operate normally if a cycle was already running — it is only the controls that are locked. This can catch people off guard, especially if the child lock was activated accidentally by leaning against the panel or pressing buttons in the wrong sequence.
The good news is that deactivating child lock takes only a few seconds and requires no tools or technical knowledge whatsoever.
Causes
- Accidental button press activating child lock — The most common reason CL appears is that someone has inadvertently held the Start button long enough to trigger the lock. This can happen when wiping down the panel, leaning against the machine, or pressing buttons quickly in sequence.
- Child or pet pressing the control panel — Young children or even pets brushing against the panel can hold a button down long enough to engage the lock. The machine gives no audible warning when this happens, so it can seem to appear out of nowhere.
- Child lock left on from a previous use — If another household member activated child lock deliberately and did not mention it, the next person to use the machine will find the controls unresponsive. The CL indicator remains active across power cycles on many Bosch models.
- Power interruption resetting display state — In rare cases, a brief power cut or surge can cause the machine to resume with the child lock indicator showing, even if it was not intentionally set. This is a display quirk rather than a fault.
- Unfamiliar model or shared household — In rental properties or shared homes, a previous occupant may have set the child lock and the next user simply does not know how to clear it. Because CL looks like an error code, it is often misread as a malfunction.
Step-by-Step Fix
- 1
Confirm the display is showing CL
Look at the display panel and check that the letters CL are visible. On some Bosch models it may flash, while on others it stays lit steadily. Make sure you are not confusing it with another code such as E or F followed by a number, which would indicate an actual fault.
- 2
Make sure the machine is powered on
The child lock can only be deactivated while the machine is switched on. If the display is blank, press the power button once to wake the machine. You do not need to start a programme — just having the machine on standby is enough.
- 3
Press and hold the Start button for five seconds
Locate the Start/Pause button — usually labelled with a triangle or the word Start — and press and hold it continuously for a full five seconds. Keep steady pressure on it; releasing too early will not deactivate the lock. You should see CL disappear from the display.
- 4
Check your model's specific button combination
On a small number of Bosch models, child lock is deactivated by holding a different button or a two-button combination rather than Start alone. If holding Start for five seconds does not work, consult your user manual or check the label inside the door or on the back of the machine for the correct sequence.
- 5
Test the controls
Once CL has cleared, press a programme selector or temperature button to confirm the panel is responding normally. If the buttons work as expected, the child lock has been successfully deactivated and the machine is ready to use.
- 6
Power cycle the machine if CL reappears immediately
If CL comes back on its own within a few seconds of being cleared, switch the machine off at the mains, wait 60 seconds, and switch it back on. Then repeat the hold sequence. A persistent CL that cannot be cleared may point to a stuck button or a control board issue rather than a simple lock activation.

When to call a service technician
In the vast majority of cases, CL clears instantly with the button-hold method described above. However, if you have followed all the steps and the CL indicator refuses to clear, or if it disappears briefly and then reappears on its own without anyone touching the panel, this may indicate a stuck or faulty button on the control panel, or a problem with the main control board that is misreading button inputs.
Similarly, if the display is showing CL alongside other codes, or if the machine is completely unresponsive even after a full power cycle, contact a qualified service technician. These symptoms suggest a hardware fault that goes beyond a simple lock setting.

Frequently Asked Questions
Will CL go away on its own if I just leave the machine?
No. Child lock stays active until you manually deactivate it by holding the Start button for five seconds. It does not time out or reset by itself, and it will remain on even if you switch the machine off and back on again. You need to follow the deactivation steps each time.
Can I still run a wash cycle with child lock on?
If a programme was already running when child lock was activated, it will continue to completion — the lock only prevents changes to the controls. However, you cannot start a new cycle, change settings, or cancel a programme while CL is active. Deactivate the lock first, then select your programme.
Why does my Bosch washing machine keep going into child lock mode by itself?
If child lock activates repeatedly without anyone deliberately setting it, the most likely cause is a sticky or partially stuck button on the control panel that is registering as a long press. Check each button for smooth movement. If a button feels stiff or does not click properly, the control panel or interface board may need to be inspected by a service technician.
Is CL the same as a fault code on a Bosch washing machine?
No. CL is purely a status indicator showing that the child lock feature is switched on. It does not mean anything is broken or malfunctioning. Actual fault codes on Bosch machines typically appear as a letter followed by one or more numbers, such as E18 or F21. If you see CL, the fix is simply to deactivate the lock.
Does every Bosch washing machine have a child lock feature?
Most modern Bosch washing machines include child lock as a standard feature, though the exact button used to activate and deactivate it can vary between models and series. If the Start button hold does not work on your machine, check your user manual for the correct method — some models use a dedicated key symbol button or a two-button combination instead.
