DC stands for "Door Check" and means your washer has detected a problem with the door latch or door sensor

When DC appears on your Samsung washer's display, the machine is telling you it cannot close or lock the door properly. This is a safety feature—the washer will not start a cycle until the door closes completely and the latch engages. The error can come from a stuck door, a misaligned latch, debris blocking the sensor, or a faulty latch assembly itself.

The good news is that DC errors are usually fixable without calling a technician. Most of the time, the problem is something straightforward you can clear in a few minutes. If the door physically closes but the error persists, the latch mechanism or sensor may need replacement.

Key Takeaways

  • DC means the door latch or sensor is not registering as closed, and the washer will not run until this is resolved.
  • Check first that nothing is blocking the door from closing fully, including wet clothes bunched in the frame or debris on the rubber seal.
  • If the door closes but DC remains, try unplugging the washer for 5 minutes to reset the sensor, then plug it back in.
  • If DC persists after a reset, the door latch assembly or the sensor itself may be worn out and need replacement.

Clear visible obstructions from the door and seal

Start by opening the door fully and looking at the rubber gasket that runs around the inside edge of the door frame. Lint, fabric, or small objects can get caught here and prevent the door from seating properly. Wipe the entire gasket with a dry cloth, paying special attention to the corners and the bottom where debris collects.

Next, look at the door itself and the frame it closes into. Make sure no clothing is bunched up in the way, and check that the door swings freely without rubbing or catching. Close the door slowly and listen for any scraping sounds. If the door closes smoothly and the gasket is clear, move to the next step.

Unplug the washer and wait 5 minutes to reset the sensor

Unplug the washer from the wall outlet or turn off the circuit breaker that controls it. Wait a full 5 minutes—this gives the control board time to clear its memory and reset the door sensor reading. After 5 minutes, plug the washer back in or turn the breaker back on.

Open and close the door once firmly, then try to start a cycle. If the DC error is gone, the sensor had straightforward registered a false reading and the reset cleared it. This is the most common fix and solves the problem for many users.

Check the door latch for damage or wear

The door latch is the mechanism that physically locks the door shut. On Samsung washers, it is usually located on the inside edge of the door frame, near where the door closes. Open the door and look for the latch—it is a small plastic or metal piece that the door pushes against when it closes.

Press the latch gently with your finger. It should move slightly and then spring back. If it feels stuck, does not move at all, or looks cracked or broken, the latch assembly needs replacement. You can order a replacement latch from Samsung or a parts supplier using your washer's model number, which is printed on a label inside the door frame or on the back of the machine.

Clean the door latch sensor area

Some Samsung washers have a small sensor that detects when the door is closed. This sensor can get dirty or blocked by lint and stop working correctly. Look for a small dark button or switch on the door frame, usually near where the latch sits. Gently clean around this area with a dry cloth or a soft brush to remove any lint or dust.

If you see any visible dirt or corrosion on the sensor itself, use a slightly damp cloth to clean it, then dry it thoroughly. Do not use water directly on the sensor—just a barely damp cloth. After cleaning, close the door and try to run a cycle again.

Replace the door latch assembly if it is broken

If the latch is visibly cracked, the door will not stay closed, or the DC error persists after cleaning and resetting, the latch assembly needs to be replaced. You will need your washer's model number to order the correct part. Find this number on the label inside the door frame or on the back of the machine, then search for "Samsung [model number] door latch" online.

Replacement latches typically cost between $30 and $80 and come with instructions. The replacement usually takes 15 to 30 minutes and requires only a screwdriver. If you are not comfortable doing this yourself, a service technician can install it for you, though that will add a service call fee.

When to call a Samsung service technician

If you have cleared obstructions, reset the washer, cleaned the sensor, and the DC error still appears, the problem is likely inside the door assembly or in the control board itself. At this point, a technician with diagnostic tools can pinpoint the exact cause and replace the faulty part.

Contact Samsung support through their website or call the number on your warranty paperwork. Have your model number ready. If your washer is still under warranty, the repair may be covered at no cost. If it is out of warranty, ask for an estimate before authorizing the work.

Frequently Asked Questions

Can I run my washer with the DC error showing?

No. Samsung washers will not start a cycle when DC is displayed because the safety lock cannot engage. The machine is designed this way to prevent water from leaking or the door from opening mid-cycle. You must clear the error before the washer will operate.

Does DC mean I need a new washer?

Almost never. Most DC errors are caused by a stuck door, debris in the seal, or a faulty latch—all of which are inexpensive to fix. Even if the latch assembly needs replacement, that part costs $30 to $80 and takes less than an hour to install.

Will unplugging the washer erase my settings?

No. Unplugging for 5 minutes resets only the sensor reading, not your saved cycles or settings. When you plug it back in, your preferences will still be there. This reset is safe and is often the first troubleshooting step Samsung recommends.

What if the door latch looks fine but DC keeps appearing?

The sensor itself may be faulty, or the control board may be misreading the door status. Try cleaning the sensor area thoroughly, then reset the washer again. If DC returns, contact Samsung support—the sensor or control board may need replacement.

Is it safe to force the door closed if it is stuck?

No. Forcing a stuck door can crack the frame or damage the latch permanently. If the door will not close smoothly, something is blocking it or the latch is misaligned. Stop, investigate what is in the way, and clear it before trying again.
