Samsung Washer dS / dC — Door open during cycle

Samsung Washer · Error code dS

What dS Means

The washer sensed the door is not fully latched after the cycle started. dS/dC stops the cycle immediately for safety. Often a partially shut door or laundry caught in the seal.

Symptoms

  • Cycle stops shortly after start
  • Door release feels normal but unit won't run
  • Code clears briefly when door is reseated then returns

Common Causes

1
Laundry pinched in door seal

A sock or shirt corner prevents full latch engagement.

2
Worn door strike or latch

Plastic latch hook wears and no longer seats the switch.

3
Failed door lock assembly

Solenoid or microswitch in the door lock is bad.

How to Fix It

  1. Open door, clear any laundry from the seal/boot, and firmly push the door shut until you hear it click.
  2. Inspect the door strike (the metal/plastic hook on the door) for wear or play.
  3. Power-cycle the washer at the breaker for 60 seconds.
  4. If the code returns with no obstruction, replace the door lock assembly.
  5. If a new lock doesn't fix it, suspect the main control PCB.
