Samsung Wf8602Ngw "de" Error
Hi,
Would anyone be able to help diagnose the fault with my Samsung WF8602NGW washing machine. The machine turns on and I can select a programme to use but when I press the start button there is a short pause and I get a flashing "dE" error code along with four audible beeps and the machine fails to start a cycle. I have searched around and all I can find is the error relates to a door open error, so I have purchased and fitted a new door switch (the one that fixes to the body of the machine that the door latch fits into) but this hasn't made a difference to the error. Any help would be greatly appreciated.

Samsung WF8602NGW showing dE door error due to broken wire to door interlock
- The problem
- Samsung WF8602NGW powered up and allowed programme selection, but when Start was pressed it paused briefly, gave a flashing dE error with four beeps, and would not begin the cycle. Replacing the door interlock did not cure the fault.
- Likely cause
- Confirmed damage to the door interlock wiring harness. The brown wire had been worn through by contact with the outer drum, so power was not reaching the door interlock and the machine reported the door as open.
- What fixed it
- The damaged wire in the harness to the door interlock was cut back, re-soldered and insulated with heat shrink. After this repair the machine worked normally again.
- Checks to try
- Observed flashing dE error and four beeps when Start was pressed
- Door interlock replaced with a new part but fault remained
- Advice given to check the door catch for looseness, damage or broken spring
- Confirmed the door interlock requires energising before continuity is made
- Final inspection found the door interlock wiring harness damaged, with the brown wire completely worn through
- Parts or tools mentioned
- door interlock
- multimeter
- wire harness
- solder
- heat shrink
Safety: Do not bypass the door interlock. If wiring damage cannot be repaired safely, further diagnosis should be carried out by a suitably qualified appliance engineer.

The washing machine is convinced the door is open. The first thing to check is that the door catch which pushes into the door interlock isn't loose, damaged or the spring broken if fitted. When the door closes the door catch needs to activate the door interlock. Try a little wd-40 as a long shot worth trying but if you can't see a problem and you've replaced the door interlock you'll be better off getting an engineer in.

Is there a way to test the new door interlock with a multimeter to see if its working as expected. Both the old and new interlock do not make a connection when running a meter across them but I suspect the switch needs power to activate.
No it needs a bi-metal strip and coil inside it be energised before the connection is made. If you wire it up wrong it will not work (or blow up) but if you know you wired it up right, or it had a connector plug that could only fit one way, and you know the connections to it are all ok then you have to assume it's nothing to do with the door interlock on the basis that the chances of both the original door interlock and a brand new one having the same fault are very slim indeed.

Just a quick update. Managed to get the machine fixed today after some help from a friend who noticed that the wire harness which connects to the door interlock had been damaged by contact with the outer drum wearing its way completely through the brown wire. Cut, re-soldered and heat shrunk the wire and now the machine is working perfectly again. So the "dE" error was correct as power was not making its way to the door interlock. Thanks for all of the help and suggestions.
