What Does the UNLOCK Code Mean?

Samsung's control lock feature is called Child Lock and displays CL when active. It is activated and deactivated the same way — by holding two specific buttons for 3 seconds. The two buttons vary by model. If you do not know your model's combination, try Sanitize + Hi-Temp first, which works on most recent Samsung dishwashers.

Most Likely Causes

Based on aggregated repair data, here is the probability breakdown for this error code:

Child lock activated by accident during panel cleaning40%

Symptoms You May Notice

  • All buttons including Power are unresponsive
  • Lock indicator light illuminated on panel
  • Machine appears completely dead but display has power

Can you reset a Samsung dishwasher to clear the UNLOCK code?

Child lock does not require a machine reset to clear. Hold the designated two-button combo for 3 seconds. If unknown, a circuit breaker reset (off 30 seconds) will clear the lock state.

Frequently Asked Questions

What buttons unlock a Samsung dishwasher?
On most current Samsung models, hold Sanitize + Hi-Temp simultaneously for 3 seconds. On some models, it is a single button with a lock symbol held for 3 seconds. Check your panel for the lock icon to identify the correct button.
Why does my Samsung dishwasher show CL?
CL means child lock is active. It was likely activated accidentally by pressing and holding two buttons at the same time, often when wiping the control panel. Hold Sanitize + Hi-Temp for 3 seconds to deactivate.
Can I lock my Samsung dishwasher on purpose?
Yes. The same two-button hold that unlocks it will also activate it. Hold Sanitize + Hi-Temp for 3 seconds when the machine is on standby to enable child lock. CL will appear on the display.
