Samsung Washer DC Error Code: Door Not Latched

Quick Answer

The DC error on a Samsung front-load washer means the door latch circuit is open. The machine will not start or will pause mid-cycle. Most cases are fixed by firmly pushing the door closed until the latch clicks audibly. If the door closes but DC persists, the latch hook may be bent, the strike plate misaligned, or the door latch assembly switch may have failed.

What Does the DC Code Mean?

DC is a safety interlock code. Samsung washers require a confirmed door closure signal before allowing any water to enter or drum rotation to begin. Mechanical latch failures and electrical switch failures both produce DC.

Most Likely Causes

Based on aggregated repair data, here is the probability breakdown for this error code:

Door not pushed fully closed to engage latch40%

Door latch hook bent or broken, not engaging strike plate24%

Door strike plate misaligned due to worn door hinges14%

Clothing or debris caught in the door opening blocking full closure12%

Door latch assembly switch failed (no continuity when latched)10%

Symptoms You May Notice

Can you reset a Samsung washer to clear the DC code?

The DC code clears automatically once the door is confirmed closed. No manual reset required. If the code persists after latching, unplug for 60 seconds to clear any residual fault signal.

Frequently Asked Questions

Why does my Samsung washer show DC mid-cycle when the door was already closed?

Mid-cycle DC usually means the door switch momentarily lost contact. This is often caused by a door latch that is beginning to fail. The vibration of the drum can cause marginal latch contact to open briefly.

Can I adjust the Samsung washer door strike plate without buying new parts?

Yes. The strike plate is held by two screws on the front panel. Loosen the screws, shift the plate slightly inward, and retighten. Test door closure and adjust until the latch clicks firmly.

Is the DC code the same as the DE code?

They share the same root fault but DC is the primary code on newer firmware while DE appears on older models. Both are door latch or switch failures and use the same replacement part.
