Samsung washer dC3 error: Add Door is not closed and locked

Samsung specifically defines dC3 (and ddC) as an Add Door error on washer models equipped with that small secondary door. The control cannot confirm that the Add Door is closed and locked, so troubleshooting should stay focused on the Add Door opening, latch, trapped items, and visible damage rather than the main washer door.

Model check required. dC3/ddC is specific to Samsung Add Door-equipped washer families. If the washer has no Add Door, verify the exact code and model before using this guide.

Can the washer positively confirm the Add Door is closed and locked?

dC3 clears after reseating the Add Door

The secondary door was not fully seated. Keep laundry clear of the Add Door opening before restarting the cycle.

The Add Door looks closed but dC3 remains

The latch alignment or closed/locked feedback may not be confirming correctly. Arrange model-specific service rather than forcing the door.

The washer has no Add Door

Recheck the display and exact model documentation. Samsung's dC3 definition applies to Add Door-equipped washer families.

Frequently asked questions

What does Samsung washer dC3 mean?

Samsung defines dC3/ddC as an Add Door error: the small secondary door is not detected as closed and locked.

Is dC3 the same as FL?

No. Samsung places FL in the general main-door error group, while dC3/ddC is specifically the Add Door error on equipped models.

Should I force the Add Door shut?

No. Clear trapped items and close it normally. Forcing a damaged or misaligned latch can worsen the problem.
