Samsung Washer Error Code DC

The DC error code on a Samsung washer signals a door operation failure. The machine detected that the door either did not open when commanded to unlock, or did not lock correctly after closing. The root cause is usually a deformed door hook, a door that was forced open during a cycle, or steam pressure during a Boil wash cycle interfering with the latch. The door switch resistance across pins 1 and 3 should measure around 175 ohms, and a deviation from that value points to a switch or wiring problem.

It is not safe to continue using the washer while the DC error is active. The code indicates the door latch is not functioning reliably, which means the door may not be fully secured during a cycle. Running the machine in this state could allow the door to open under water pressure, creating a flood or personal injury risk. The issue should be diagnosed and resolved before resuming normal use.

A power reset, done by unplugging the washer for a minute and restarting, may temporarily clear the DC error code. However, if the underlying cause is a deformed door hook, a failing door switch, or damaged wiring, the error will return during the next cycle or the next Boil wash. A reset is useful for confirming whether the fault is intermittent, but it is not a fix. The physical components and wiring should be inspected and tested before relying on the machine again.

Some causes of the DC error are DIY-friendly. You can visually inspect the door hook for deformation, check wire connections along the door harness for looseness or damaged insulation, and verify the door switch resistance with a multimeter set to ohms. If the reading across pins 1 and 3 is far from 175 ohms, replacing the door switch is a moderately straightforward repair. Deformed door hooks or a damaged latch assembly will also require part replacement, but the repair is accessible without specialized tools in most cases.

Repair costs depend on the root cause. A replacement door switch or door hook component typically costs between $15 and $60 for the part alone. If professional labor is involved, total repair costs including diagnosis and installation commonly range from $100 to $250. Wiring issues that only require connector repair or reseating may cost less if no parts need to be ordered.
