What DC1 means

On the Samsung WD90F27 series and WD90F53AVS Laundry Combo, DC1 means the door switch lock and unlock is not working properly. The unit tried to lock or release the door and did not get the expected result. You will see DC1 on the display and the cycle will not start or will stop. Dirt around the door, or a door that is not pushed fully shut, can cause it.

Common causes of DC1

  • Foreign substances around the door and latch
  • Door not pushed fully closed
  • Door lock and switch assembly
  • Wiring to the door lock
✓ One safe check you can try

1. Open the door and check around the opening and the latch for foreign substances such as lint, coins or detergent residue. 2. Wipe the area with a dry cloth. 3. Push the door closed firmly until it clicks. 4. Try the cycle again. 5. Do not force the door if it will not open. Call us instead.

! Why to stop there
  • After cleaning, we still cannot tell whether the lock itself or its wiring is the cause, so we test the lock cycle.
  • We inspect the latch and switch for wear before recommending any part.
  • The written price is settled before the work, and our workmanship is backed for 30 days.
Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

DC1DC1 questions
Why does a dirty latch cause DC1?

The lock needs to move freely and the switch needs to confirm the position. Residue or small objects can block that movement, so the unit reports a lock problem.

What if the door will not open?

Do not pull on it. Wait for the unit to finish its release, and if it stays locked, call us so the latch is not damaged.

Does DC1 mean the whole unit is broken?

No. It points only to the door lock circuit. After cleaning and a firm close, if it returns, we test the lock. Wipe the latch and the seal with a dry cloth before you decide the lock is the cause.
