Quick answer: On a Samsung Washer, the dC2 error code means the machine detected that the door was opened during an active wash or spin cycle. The Samsung Washer dC2 is a door-open-during-cycle fault and is a safety code — the machine stops to prevent water from escaping. In most cases the door was physically opened mid-cycle, but dC2 can also appear if the door lock assembly loses its hold during a cycle due to a worn latch or vibration.
The Samsung Washer dC2 code is triggered when the door open sensor signals that the door has separated from the locked position during an active cycle. On front-loader Samsung Washers, this can occur if the door latch hook is worn and the door “pops” open slightly during the vibration of a high-speed spin. The machine stops immediately when it detects this condition.
Follow the steps below one at a time — many error codes can be fixed faster than they look.
Step 1 — Check if door was opened: If someone opened the door during the cycle, simply close it and press Start/Pause to resume.
Step 2 — Inspect the door latch hook: With the door open, examine the plastic latch hook for signs of wear, rounding, or cracking. A worn latch hook will not hold firmly in the strike when the machine vibrates.
Step 3 — Test the door lock: After replacing the latch hook if worn, run a spin cycle and listen for any movement or rattling at the door. If the door still releases during spin, the door lock assembly itself needs replacement.
Step 4 — Check for excessive vibration: If the washer vibrates unusually during spin, an unbalanced drum load could be stressing the door latch. See our guide on Samsung Washer DC error for unbalanced load troubleshooting.
