Samsung Washer DC Error Code – Door Lock Problem Fix

If your Samsung washer is showing the DC error code, it's indicating a door lock problem. This comprehensive guide will help you diagnose the issue and get your washer door locking properly again.

What Does the Samsung DC Error Code Mean?

The DC error code on Samsung washers indicates a door lock error. This means the washer cannot lock the door properly to start a cycle, or the door won't unlock after the cycle completes.

When the washer detects a door lock problem, it triggers the DC error and prevents the cycle from starting to ensure safety and prevent water leaks.

Most Common Causes

• Faulty door lock assembly – Door lock switch has failed or is stuck
• Misaligned door latch – Door not closing properly or latch is bent
• Loose or damaged wiring – Wire connections to door lock are corroded
• Debris in door latch – Lint or objects blocking the latch mechanism
• Failed control board – Main control board cannot communicate with door lock
• Door hinge issue – Door not aligning properly due to loose hinges
