dC
Samsung Washing Machine
Severity: MinorWhat Does This Error Mean?
The dC error means your Samsung washer thinks the door is open or not locked properly. The machine won't start a cycle until the door is fully closed and latched. This is a safety feature to prevent water leaks and injuries.

- Misaligned door hinge
How to Fix It
-
Open the door and check for clothing or debris caught in the rubber door seal.
Run your hand around the entire seal. Small items like socks or tissues often get trapped there.
-
Close the door firmly until you hear it click.
Push the door until you feel and hear the latch engage. Don't slam it — just press firmly.
-
Inspect the door latch for visible damage or wear.
Look at the hook on the door and the slot on the frame. Make sure nothing is cracked or bent.
-
Unplug the washer for 60 seconds, then plug it back in.
This resets the control board and can clear a false door error.
-
If the error persists, the door lock assembly may need replacement.
The electronic lock can fail over time. A technician can swap it out quickly.
When to Call a Professional
If the door closes properly but the error won't clear, the door lock assembly may be faulty. This is an electronic part that a technician should replace. Expect repair costs of $100–$200 including parts and labor.
Frequently Asked Questions
Why does my Samsung washer say dC when the door is closed?
The door lock switch may be worn out or malfunctioning. It can't detect that the door is actually latched. Try unplugging the washer for 60 seconds to reset it. If it keeps happening, the lock assembly needs replacing.
Can I open the door during a wash cycle?
On most Samsung front-load washers, the door locks during a cycle. You need to pause the cycle first, then wait for the door to unlock. Opening the door mid-cycle will trigger the dC error when you try to restart.
Is the dC error dangerous?
No, it's not dangerous. It's actually a safety feature. The washer is protecting you from water spilling out. Just make sure the door is properly closed before starting a cycle.
