Dishwasher Child Lock: What It Is and How to Activate It
Short answer: A dishwasher child lock, also called a control lock, disables the control panel to prevent accidental button presses that could change cycles, start a wash, or cancel a program. It is a safety feature useful when young children are around. Activation usually involves pressing and holding a button or a combination of buttons for a few seconds. Most modern dishwashers include this feature, and you can find models with top-mounted controls for extra protection.
What is a dishwasher child lock?
A dishwasher child lock is a safety feature that disables the control panel so that pressing buttons does not change the selected cycle, add options, or start or stop the dishwasher. It is designed to prevent children, or anyone accidentally brushing against the panel, from interfering with a wash cycle.
This feature is sometimes called a control lock, button lock, or key lock. It does not physically lock the dishwasher door; it only locks the controls. The child lock is separate from the door latch, which is a mechanical safety mechanism that prevents the door from opening while the dishwasher is running.
How does the child lock work?
When the child lock is active, the control panel ignores input from all or most buttons. The dishwasher continues to run its current cycle, but you cannot change settings, add a delayed start, or pause the cycle unless you deactivate the lock first. Some models also disable the Start button to prevent a child from triggering a wash after loading.
The lock is typically toggled on and off by pressing and holding a specific button for a few seconds, or by pressing a combination of two buttons simultaneously. The exact method varies by model, so you should always check your owner's manual for the correct sequence for your dishwasher.
In most cases, the child lock remains engaged even after the cycle finishes. You will need to unlock the controls to open the door or adjust anything, which adds a deliberate step that discourages accidental changes.
How to activate and deactivate the child lock
Activation steps are not universal, but the most common methods are listed below. Always test the lock after engaging it to confirm that the buttons do not respond.
Common methods you may find in owner's manuals:
- Press and hold the Start button for about three seconds until an indicator light appears.
- Press and hold the Delay Start button for a few seconds.
- Press and hold the Start and Cancel buttons together for a few seconds.
- Press a dedicated child lock key or a lock symbol on the control panel.
- Navigate to the lock setting on models with a digital display and confirm it.
When to use the child lock
Use the child lock whenever there are curious children near the dishwasher who might press buttons. This is especially important if the control panel is at a height that is easy to reach, such as on a front control panel or a low countertop.
Even if you do not have young children, the lock can prevent accidental changes when you are cleaning the panel or when an object brushes against the controls. It adds a layer of protection during busy kitchen times.
If you want a dishwasher that is inherently safer for homes with kids, consider models with top-mounted control panels, which are less accessible to small hands. Many manufacturers offer this design, and you can compare options in our best 24-inch dishwashers and best built-in dishwashers guides.
What to look for in a dishwasher with a good child lock
A good child lock is easy to activate but hard for a child to figure out. Look for a button or combination that requires deliberate pressure and, ideally, a visual indicator that the lock is on. Some models show a small lock symbol or an LED light on the panel.
Also consider the layout of the controls. Dishwashers with controls on the top edge of the door are naturally safer because they are out of reach for toddlers. If you prefer front controls, check that the buttons are recessed or have a tactile response that requires firm pressure.
When comparing models, pay attention to how the child lock interacts with other features. On some dishwashers, the lock does not disable the Power button, so a child could still turn the machine off. Others lock everything. Reading the specifications or owner's manual will clarify what is covered.

Child lock and other safety features
The child lock works alongside other safety features such as the door latch, which prevents the door from being opened mid-cycle, and the auto-off function that shuts down the dishwasher after a period of inactivity. These features work together to reduce risks in a kitchen.
If you are using the delay start option, remember that a child can still activate a delayed cycle if the lock is not engaged. Always enable the child lock after loading and setting the cycle, especially if you plan to leave the dishwasher unattended.

Questions
Does the child lock prevent the dishwasher from opening?
No. The child lock only disables the control panel. The door latch is a separate mechanical safety device that prevents the door from opening while the dishwasher is running, but it is not controlled by the child lock.
Can I still open the dishwasher during a cycle if the child lock is on?
The child lock does not affect the door latch. Most dishwashers prevent the door from being opened while a wash cycle is in progress, but that is due to the latch mechanism, not the child lock. You may need to cancel the cycle first, which usually requires unlocking the controls.
Does the child lock drain extra energy or water?
No. The child lock is a control feature that requires no additional water or energy. It simply disables the buttons and does not alter the wash performance.
Is the child lock standard on all dishwashers?
No. Many modern dishwashers include a child lock, but it is not universal. It is more common on built-in models, while some compact and countertop units may omit it. Check the specifications for the specific model you are considering.
I forgot how to turn off the child lock. What should I do?
Refer to the owner's manual for your specific model. Manuals are usually available online from the manufacturer's website. A common method is to press and hold the Start button or a combination of Start and Cancel for a few seconds, but this varies. If you cannot find the manual, contact the manufacturer's support service.
