When the Samsung front load washing machine displays a 'Red Key' symbol, it indicates that the child lock feature is active, preventing the door from being opened. The child lock is designed to keep the washing machine settings from being changed or the door from being opened accidentally, especially if there are young children around.
To open the door when the child lock is engaged, you need to deactivate the feature. Here's how you can do it:
Look for the 'Red Key' symbol on the display panel or control panel of the washing machine.
Press and hold the 'Temp' and 'Options' buttons simultaneously for about 3 to 5 seconds until the 'Red Key' symbol disappears. Some models might have different buttons, but 'Temp' and 'Options' are commonly used for this purpose.
Once the child lock is deactivated, you should be able to open the door normally.
If pressing the 'Temp' and 'Options' buttons doesn't work, consult your washing machine's user manual for specific instructions on how to deactivate the child lock for your model. The location of the buttons and the process may vary slightly depending on the exact model of your Samsung front load washing machine.
If you no longer have the user manual, you can typically find it online by searching for your washing machine's model number on the Samsung support website. Additionally, you can contact Samsung customer support for further assistance if needed.
