What Does Error Code dC Mean on a Samsung Washing Machine?

Door cannot close — door detected open or unlatched during operation.

The control board monitors the door latch switch and expects a closed signal before and during a cycle. dC fires when the board never sees a confirmed latch engagement or loses it mid-run, indicating the door isn't mechanically seated. This differs from dE, which points to the lock's electronic engagement or the solenoid, and from FL, a lock-failure state. dC typically reflects a physical closing obstruction, misalignment, or a worn latch that won't register.

Models affected: Front-load Samsung washers with a door latch/lock circuit, including models such as the WF45T6000AW, WF45R6100AP, WF42H5000AW, and WF50BG8300AV
What owners report: Owners commonly report dC appearing right at cycle start, often after overloading when a sleeve or towel corner gets caught in the gasket fold. The quick win is usually opening the door, tucking laundry fully inside, and reclosing firmly; if the door looks flush but the code returns, a sagging hinge or tired latch is the more likely culprit.

Frequently Asked Questions

Can I keep using my Samsung Washing Machine when error dC appears? +
You often can for a cycle or two, but the door-lock issue behind dC will keep interrupting normal operation until it is fixed. Plan the repair rather than ignoring the code.
What most commonly causes dC on a Samsung Washing Machine? +
Across reported Samsung washing machine repairs, the most frequent is laundry pinched in the door seal (40% of cases), misaligned door hinge or striker (30%), then door latch assembly worn (20%). Check them in that order before replacing any parts.
dC keeps coming back after a reset — what should I check next? +
A reset only clears the stored dC fault; if it returns, the door-lock problem is still present. Move on to the physical checks — clear the door seal, then check hinge and striker alignment — since the code will reappear until the root cause is resolved. This is a beginner-friendly job needing only basic hand tools.
How much does it cost to fix Samsung Washing Machine error dC? +
A DIY repair typically runs $0–$75 in parts, versus $130–$240 for a professional service call, so handling it yourself saves around $130. Expect the work to take about 10–20 minutes.
Which Samsung Washing Machine models show error dC? +
dC is documented on Front-load Samsung washers with a door latch/lock circuit, including models such as the WF45T6000AW, WF45R6100AP, WF42H5000AW, and WF50BG8300AV. Other units sharing the same control platform can display it too, so the fixes here generally transfer across the series.
