Samsung Washer DC / dE Error: Door Lock Fix & Switch Part (#DC64-00519D)
Quick Answer: The DC (Door Check) or dE (Door Error) code on a Samsung washing machine means the control board does not detect the door or lid as securely locked. Replacing the Door Lock Switch Assembly (#DC64-00519D for front-load or #DC34-00025E for top-load) fixes this issue in 10 minutes.
⚠️ Watch Out on Top-Loaders (DC vs UB): On some Samsung top-load washers without a dedicated 'UB' display, 'DC' can also be triggered if the tub slams against the lid switch during an unbalanced spin! If DC happens at the very start of the wash (within 5 seconds of pressing Start), it is 100% the Door/Lid Lock Switch.

Step 1: Free 2-Minute Reset & Test (Try This First)
Before ordering replacement parts, perform this quick reset sequence to rule out a temporary sensor trip:
- Open the washer door and check that no socks or hoodie drawstrings are pinched against the rubber boot gasket.
- Inspect the metal or plastic strike hook on the door to ensure it isn't bent or loose.
- Push firmly on the door right next to the handle while pressing Start: if you do not hear a sharp 'CLICK' from the lock mechanism, the Door Lock Switch (#DC64-00519D) has burned out.
