Samsung Washing Machine Error Code dE — How to Fix (Door detected as open during cycle)

Field note: dE is almost always the door/lid switch or strike, not the main board. On Samsung Washing Machines the control will not start a cycle if it cannot prove the door is closed and locked. Check the strike alignment and the lock click before any board. A door that ‘looks closed’ still throws this.

What this code is not

• Not a wash-motor or heater failure.
• Not fixed by a 3-second cancel if the strike is bent or the latch is gummed with detergent.
• A door that slams but does not click the switch will keep dE forever.

If you’re seeing the error code dE on your Samsung Washing Machine, it means the door was detected as open during a cycle. This can cause the machine to stop working and display the error code. The error code dE is a common issue that can be caused by a variety of factors, including a faulty door sensor switch, misaligned door, or loose connections.
