the Samsung top load washing machine model WA78K1 doesn't have a child lock feature. However, if Samsung has introduced this feature in a later version or a different model, the process to turn off the child lock mode might differ. I recommend consulting the user manual specific to your washing machine model for the most accurate instructions.
In general, to turn off the child lock mode on most Samsung washing machines, you can try the following steps:
Look for the child lock button or icon on the control panel. It is often represented by a small lock symbol or a key symbol. On some models, it might be a combination of buttons or require a specific sequence of key presses.
Press and hold the child lock button for a few seconds until you hear a beep or see a notification on the display that the child lock is deactivated.
Once the child lock is turned off, you should be able to use all the functions and buttons on the control panel as usual.
If you can't find the child lock button or icon or if the above steps don't work, it's best to refer to the user manual for your specific model or contact Samsung customer support for assistance. Keep in mind that the user manuals and features may change over time, so referring to the latest information will ensure accuracy.
