The most common cause is simply that the door isn't latched properly. Clothing caught in the door seal, a warped door, or items blocking the door from closing completely will trigger this error.
The electronic door lock mechanism can wear out over time. The lock solenoid or the latch itself may fail, preventing the door from engaging even when physically closed. This is common in machines over 5 years old.
The door strike (the part the latch hooks into) can become bent or worn. Door hinges can also loosen over time, causing misalignment that prevents proper latching.
The wire harness connecting the door lock to the main control board can become loose, corroded, or damaged. This is more common in machines that have been moved or serviced previously.
In rare cases, the main control board fails to send the lock signal to the door mechanism, even though the physical lock is fine. This usually requires board replacement.
Open the door and inspect the seal area for clothing, debris, or objects preventing full closure. For washers, check that no garments are caught between the door and the rubber gasket.
Unplug the machine for 5 minutes, then plug it back in. Try closing the door and starting a cycle. This can clear false dE errors caused by electronic glitches.
Look at the latch mechanism on the door and the strike on the frame. Check for visible damage, bending, or wear. Try manually engaging the latch — you should hear a firm click when the door closes.
Use a damp cloth to clean around the door lock mechanism and strike. Buildup of detergent residue or lint can prevent proper engagement.
If the door physically closes and latches but the dE error persists, the door lock assembly likely needs replacement. This involves removing the front panel, disconnecting the old lock, and installing a new one — a repair that requires specific Samsung parts and electrical knowledge. Call a professional if you hear clicking sounds from the lock area (lock trying but failing to engage) or if the error appears intermittently.

dE stands for 'door error.' The washer has detected that the door is not properly closed or the door lock mechanism has failed to engage.
First, check that nothing is blocking the door from closing fully. Then try a power reset (unplug for 5 minutes). If the error persists, the door lock assembly may need replacement.
If the error is caused by a temporary glitch, a power reset may clear it. If it's caused by a physical obstruction, removing the obstruction will fix it. However, a faulty door lock assembly will not fix itself and requires replacement.
