Samsung Washer - DC1 Error Code

Main door lock/unlock mechanism malfunction.

Meaning

Main door lock/unlock mechanism malfunction.

The DC1 error indicates that the washer has detected a malfunction in the main door lock or unlock mechanism. Samsung explains that this code appears when the door lock fails to engage, fails to release, or does not communicate properly with the control board. Because the washer cannot safely operate with an unreliable door lock, the system halts the cycle to prevent leaks, safety hazards, or drum movement while the door is unsecured.
