Won't do anything but display error message


DE Error on Samsung washing machines (usually) means that “the door is open”. As with most error codes though you can’t take it literally because very often this error will display when the door is clearly closed. What it means is, that it thinks the door is open, presumably because it’s not getting power passed from the door interlock.

This is how you know if the door lock needs replacing or not? Well the first thing to check is that the door is closing properly. When the door is closed, the latch on the door pushes into the door interlock, it should latch firmly and activate a part inside the lock. When this part is physically pushed to one side by the door catch the interlock activates and locks the door. At the same time, power is passed from one side of the door lock to the other and on to the rest of the machine. If the door latch is broken, worn, or a spring come off etc. it may not activate the door lock inside. Of course if the door lock is faulty the same problem will occur. Maybe even a door that has dropped and is not lining up properly any more due to wear at the hinge might fail to operate the interlock properly.

It is possible for a door to close, and latch shut, but not activate the door lock properly. If everything seems OK you could always try spraying a little wd-40 into the door lock opening in case something’s stiffened up. You could also try wiggling the door up and down a bit once closed to see if it all of a sudden operates the interlock.

It’s also possible that a bad connection or broken wire on the door interlock supplying the power, the neutral return, or the power to the rest of the machine once activated is causing a fault.


Do not reach into the machine to fiddle with the door lock with the machine plugged in. Mains voltage goes to the door interlock.

The best place to get a new door interlock which is easy to replace if you are just a little handy and have a few basic hand tools is:

Please call Ransom Spares: 0844(###) ###-####a href="" target="_blank">Home » Parts » Laundry Spares » Tumble Dryers

I would call to order this part for a couple of reasons.

One, they dont list all the parts they stock on their website;-)

And two, they will make sure you order the correct part and will ship it to you the same day you call;-)

In any case, I will stick with you until this is complete.

Please rate my service kindly.

Also it is the only way I am credited for my time and expertise with you.
