Follow the step-by-step diagnosis below. The most likely fix is identified by checking power, sensor resistance, and control-board signals in order — using a multimeter and the part numbers documented in the parts reference table.

Can I keep running the equipment with this fault active?

Generally no. Faults on Appliance units are emitted when a sensor, safety, or control circuit is outside its operating envelope. Running through an active fault risks compressor, heater, or control-board damage. Diagnose and clear the fault first.

Samsung Washer Door Lock / Latch Assembly Replacement

Q: What does Samsung Washer Door Lock / Latch Assembly Replacement mean?

Door won't lock, washer won't start, or dE/DC error codes mean the door lock assembly has failed. Replacing it restores secure door locking.

Samsung Washer Door Lock / Latch Assembly Replacement — What This Part Does

The door lock assembly secures the washer door during the cycle and tells the control board the door is locked. Inside the assembly is a lock motor that drives a latch into the door strike, plus switch contacts that feed back lock status to the board. When you close the door and start a cycle, the motor engages the latch and the contacts close to prove a locked state.

The assembly fails when the plastic latch lever breaks off, the internal lock motor burns out, or the switch contacts stop making continuity. Repeated door slams, misalignment between the lock body and the door strike, or water intrusion into the connector can all damage the lock. Once the control can’t confirm a locked door, it throws a door error and refuses to fill or spin.

Signs It Needs Replacing

dE, dC, DC, door, or SDC error code on the display The control has detected that the door lock circuit is not reading the expected locked or unlocked state.
Door won’t lock when you press Start You hear no click or hum from the door area, or the lock tries but doesn’t engage the strike.
Washer won’t fill or spin even though the door is closed The machine sees an open door lock circuit and blocks the cycle from starting.
Broken or loose door latch lever The plastic lever on the lock assembly or the strike on the door is visibly cracked, bent, or missing.
Door pops open mid-cycle or during spin The lock motor or contacts have failed so the latch no longer holds under load.
Clicking or buzzing at the door but no lock engagement The lock motor is trying to move but the internal mechanism is jammed or stripped.

How to Replace It

Unplug the washer from the wall outlet and turn off the hot and cold water supply valves behind the machine.
Pull the washer forward a few inches so you can access the rear or side panel, or remove the top panel by sliding it back and lifting off if your model has top access to the lock.
Open the washer door and peel back the front edge of the rubber boot seal to expose the spring clamp that holds the boot to the front panel.
Use needle-nose pliers or a flat screwdriver to release the spring clamp from its groove and slide it off the boot, then tuck the boot into the drum to reveal the door lock assembly screws.
Unplug the wiring harness from the back of the door lock assembly, then remove the two or three screws securing the lock to the front panel and pull the old lock assembly out.
Position the new door lock assembly into the mounting holes and thread in the screws, tightening them snug but not over-tight to avoid cracking the plastic lock body.
Plug the wiring harness firmly onto the connector on the back of the new lock until it clicks.
Pull the boot seal back over the front panel lip, work the spring clamp back into its groove around the entire circumference, and check that the boot sits evenly with no kinks or folds.
Restore power and water, close the door, and run a drain/spin or rinse cycle to verify the door locks with an audible click and the washer starts without a door error code.

The Part You Need

Part	Notes
Samsung washer door lock assembly	Amazon \| Common part numbers include DC64-02032A, DC64-00519B, and DC34-00028A. Check your model and serial number plate on the door rim or inside the door opening to confirm the exact lock assembly for your washer.

If this part is failing you may also see one of these codes:

When to Call a Pro

If you disconnect the lock harness and measure resistance at the connector and find the door switch (white to green) is not around 2 ohms with the door closed, the lock contact (white to red) is not around 2 ohms when locked, the unlock contact (white to blue) is not around 2 ohms when unlocked, or the lock motor (black to brown) is not 33 to 46 ohms, the lock is electrically dead and should be replaced. If the lock tests good but you still get door errors, the wiring harness or main control board may be at fault and a technician with a schematic should trace the circuit. On some Samsung models with molded door assemblies, Samsung recommends replacing the entire door if the lock lever or strike area is damaged because the door casting does not allow a reliable lock-only repair.
