Quick answer: The Samsung dE error code (also shown as DE, dE1, or dE2) means the machine cannot confirm the door is closed and locked. Push the door firmly until it clicks shut and try starting the cycle again—this resolves the fault immediately in many cases. If the door is physically closing but dE persists, the door latch or door interlock switch has likely failed. Replacement door lock switches for Samsung front loaders are available from $36.95 and are a straightforward DIY repair.

What does Samsung dE mean?
dE is Samsung’s door error code. The machine will not start—or will halt mid-cycle—when the door interlock switch has not sent a confirmed “door locked” signal to the control board. This is a safety feature: the machine is designed to prevent the drum from spinning if there is any possibility the door could be open.
The variants—dE, DE, dE1, and dE2—all relate to door detection. On models that show dE1 or dE2, the machine is providing slightly more granular information about which aspect of door locking has failed (primary lock vs secondary lock detection), but the diagnosis process and replacement part are typically the same.
What causes Samsung dE?
| Cause | Likelihood | Fix |
|---|---|---|
| Door not fully pushed closed | Very common | Push door firmly until it clicks — free |
| Item of laundry caught in the door seal | Common | Clear the obstruction — free |
| Worn or broken door latch hook (on the door) | Moderate | Replace door handle or latch assembly |
| Failed door interlock switch (inside the machine body) | Moderate | Replace interlock switch — $37–$59 |
| Damaged door interlock wiring | Less common | Inspect and repair wiring harness |
How to fix Samsung dE step by step
- Push the door firmly shut. Press the door with your hand against the machine body until you hear and feel a clear click. On front loaders, the door sometimes needs a firm push at the outer edge near the latch. Try starting the machine immediately after closing. If it starts without showing dE, the door simply was not fully latched.
- Check for laundry caught in the door. Open the door and check around the door gasket (rubber seal). A sock, towel edge, or thin item caught between the drum and the seal can prevent the door from closing flush. Remove any obstruction and close firmly.
- Inspect the door latch and hook. Look at the door hook (the plastic or metal prong on the door that engages with the interlock). If it is visibly cracked or broken, the door cannot operate the interlock switch correctly. The handle assembly or latch hook may need replacement.
- Power-cycle the machine. Turn the machine off at the wall for two minutes, then plug back in. Occasionally a dE code is triggered by a momentary electrical glitch that clears after a reset. If dE appears again on the next start attempt, the issue is physical.
- Replace the door interlock switch. If the door closes and latches correctly but dE persists, the interlock switch inside the machine has failed. This switch detects the door hook and sends the locked signal to the control board. Match your model number (on the model sticker inside the door frame) to the correct switch:

Frequently asked questions
What is the difference between dE, dE1, and dE2?
All three indicate a door-related fault. dE1 and dE2 are more specific sub-codes on some Samsung models, distinguishing between a primary lock failure (dE1) and a secondary detection issue (dE2). In practice, the door interlock switch assembly is the component to inspect and replace in all three cases.
My Samsung shows dE but the door clicks shut — what does that mean?
If the door physically latches but dE still appears, the door interlock switch inside the machine has likely failed. The switch is what sends the confirmation signal to the control board—a click when you close the door means the latch is engaging, but the switch may not be registering this correctly.
How long does it take to replace a Samsung door interlock switch?
On most Samsung front loaders, the door interlock switch is accessible by removing the front panel or by pulling back the door gasket. The repair typically takes 30–45 minutes for a DIY-capable repair.
Can I run a Samsung washer with the door taped shut to bypass dE?
No. The interlock is a safety system and the machine will not operate if the door lock signal is not confirmed by the control board. There is no safe workaround—the switch must be repaired or replaced.
Does dE appear on Samsung top loaders?
Samsung top loaders use a lid lock rather than a door interlock. A lid lock fault on a Samsung top loader is typically displayed as a different code. See the Samsung error codes hub for top loader fault codes.
