Samsung Washer dC Error — Door Not Closed Fix

What it means

Samsung washer dC error means the door is not detected as fully closed and locked — Samsung's 'Door error'.
The cycle cannot start until the door switch confirms the door is shut and the lock has engaged.

Affected Models

  • Samsung Front Load Washer
  • Samsung Top Load Washer
  • Samsung AddWash Washer
  • Samsung EcoBubble Washer
  • Samsung QuickDrive Washer

Common Causes

  • Door not pushed fully shut (most common — push firmly)
  • Item of clothing trapped in the door seal preventing close
  • Door latch hook bent or out of alignment
  • Door lock solenoid (interlock) failed
  • Wiring loose between door switch and main control board

How to Fix It

  1. Close the door firmly.

    Push the door shut with a firm, deliberate push — not a gentle close.
    You should hear or feel a definite click as the latch engages.

  2. Check the door seal for trapped items.

    Open the door and look around the rubber seal (front-load) for socks, underwear, or scrunched clothing trapping the latch.
    Remove anything pinched there.

  3. Inspect the latch hook.

    On the door itself, find the small metal hook that engages the lock.
    It should look straight and undamaged.
    If bent, the door won't latch — the door panel needs replacement.

  4. Power-cycle the washer.

    Unplug the machine for 60 seconds, plug back in.
    This clears a one-off control board glitch.
    If dC clears, all good; if it returns immediately, the door interlock or wiring has failed.

When to Call a Professional

If the door shuts firmly with a click but dC still shows, the door interlock has failed and needs replacement — typically a 30-minute job and an inexpensive part.

Frequently Asked Questions

Why does Samsung washer dC appear when the door looks closed?

Two reasons.
First — the latch hasn't fully engaged the lock; push the door more firmly.
Second — the door interlock (the small electric solenoid that holds the door shut during the cycle) has failed and isn't reporting 'locked' to the control board.
If you get a definite click on closing but dC persists, the interlock is the cause.
