DC

Door Open or Door Not Closed Properly

Severity

Medium

If your Samsung Washing Machine is displaying the error code DC, the control board has detected a fault identified as "Door Open or Door Not Closed Properly". Understanding the root cause helps you avoid an unnecessary service call.

Owner's Summary

The machine thinks its door is open even when you close it. Before calling a repair service, check if a sock or shirt sleeve is caught in the rubber seal preventing a proper seal.

Symptoms

Washer will not start cycle, door seems closed but DC error shows

Common Causes

Laundry item caught in door seal
Worn or broken door latch hook
Faulty door lock assembly
Wiring issue to the door lock

How to Fix

1 Check door seal for trapped clothing or debris
2 Close door firmly until you hear a click
3 Inspect door latch hook for cracks or bends and replace if damaged
4 Test door lock assembly with a multimeter and replace if no continuity

Tools You'll Need

Multimeter Flashlight Replacement Gasket

These are simple, low-risk fixes most homeowners can do with tools already in a basic toolbox.

Technical Explanation

The door interlock sends a 120V signal to the PCB confirming door closure. If the bimetal thermal actuator inside the lock fails to confirm engagement within 5 seconds of a cycle start command, the board logs DC and disables all motor outputs.

Is It Safe to Keep Using?

Safe. The machine will simply not run until the door issue is resolved — this is a safety feature.

Technician's Pro Tip

Before replacing the lock, press the door firmly with your knee while pressing start — if the cycle begins, the latch hook is worn and just needs replacing (a $15 part).
