Samsung Washer dC Error Code

Door or lid not closed and locked. What it means, which models show it, and how to clear it, easiest fix first.

SamsungAll Samsung washer codes

dC
Moderate DIY

The washer has no confirmation that the door or lid is fully shut and latched, so it will not start or continue the cycle. Often a piece of clothing is caught in the door, the latch is dirty, or the door is not pushed fully closed. A broken latch or a faulty door lock assembly is the usual part failure.

Compatible models

Samsung doesn't publish a model list for this code; it appears on Samsung washers with a digital display. Check your owner's manual.

Also shown as

Also shown as dE, dE1, dE2, dS, d5, FL, LO, L0, dL, dC1, 1 dC, or 1dC1 depending on the model. Some front-load manuals split these up (for example FL for a failure to lock and LO for a failure to unlock), but the checks are the same. On some models a lowercase dc means an unbalanced load instead, so check your manual. ddC or dC3 refers to the small Add Door, not the main door. On FlexWash models, 1dC4 usually means the rubber button next to the upper latch is missing.

Difficulty

Start with the safe checks below; a worn part may need replacing.

Safety first: unplug the washer (or switch off its breaker) before touching filters, hoses or panels. If you smell burning or gas, or see water near the outlet, stop and call a professional.

How to fix Samsung dC

  1. Close the door firmly

    Open the door or lid, check that no clothing is caught in the seal or latch, and close it firmly until it clicks. Press Start again.

  2. Check Child Lock

    On many models, if Child Lock is on and there is water in the tub, a door code can appear even when no cycle is running, and the washer will drain itself if the door is not closed or Child Lock is not turned off within about 30 seconds. Turn Child Lock off following your manual.

  3. Inspect the latch

    Unplug the washer. Look at the door hook and the lock opening for lint, detergent buildup, or broken plastic. Wipe away any debris with a damp cloth. Never tape over, prop, or otherwise bypass the lock.

When to call a technician

If the door hook or lock is cracked or broken, or the code persists with the door clearly closed, the door lock assembly or its wiring needs service. Do not force a locked door open, as that can damage the lock.

Can I fix Samsung dC myself?

Often. The first steps above are safe checks a homeowner can do. If they don't clear dC, the cause is likely a worn part that needs replacing.

What if dC keeps coming back?

A code that returns after a reset and the checks above usually means a part is wearing out. Note when dC appears (which cycle, how often) and have your model number ready; it helps a technician bring the right part on the first visit.
