Why won't the child lock turn off on my Samsung washing machine?
Wiki Article
If the Child Lock on your Samsung washing machine won’t turn off, it can be frustrating because the machine becomes unresponsive to most buttons. You may still see the lock icon on the display, and you might not be able to change cycles, start a new wash, or adjust settings. In many cases, the machine continues running normally, but the control panel is disabled.
This issue is usually not a serious hardware fault. Most of the time it is caused by incorrect button combination, software glitch, control panel lock behavior, or sensor communication issues.
What Is Child Lock?
Child Lock is a safety feature designed to:
Prevent children from changing settings
Stop accidental interruption of wash cycles
Lock the control panel during operation
When activated, most buttons are disabled except power (in some models).
1. Incorrect Button Combination (Most Common Cause)
Why it happens
Each Samsung model has a specific button combination to activate or deactivate Child Lock. If the wrong combination is used, the lock may remain active.
Symptoms
Lock icon remains on screen
Buttons do not respond
Repeated attempts do not disable lock
Solution
Try common Samsung combinations:
Temp + Rinse (hold 3–5 seconds)
Spin + Options (hold 3–5 seconds)
Rinse + Spin (varies by model)
???? Always hold buttons for a few seconds, not a quick press.
2. Machine Still Running a Cycle
Why it happens
Child Lock cannot always be turned off while a cycle is running.
Symptoms
Lock cannot be disabled mid-wash
Buttons remain inactive
Solution
Pause or cancel current cycle
Turn machine off
Restart and then try disabling Child Lock again
3. Control Panel Glitch or Software Freeze
Why it happens
Temporary software issues can freeze the lock state.
Symptoms

Solution
Reset machine
Inspect for moisture or damage
