DE is door lock error possible main pba or wire harness check connections on new switch first .ohm wire harness If you can to check for break in wire

DE indicates a door lock error.
Either the door lock, wiring or main control board can cause this fault.
The door lock is relatively inexpensive so it would be worth trying a new door lock first.
Check the wiring between the door lock and the control board.
If a new door lock doesn't fix it and the wiring is ok you are only left with the control board.

I have a Samsung J845 front loader washing machine, A few weeks ago, no water would go into the machine, so replaced the broken solenoid. Now the water never stops going into the machine ??? The solenoid is working but not getting electrically turned off. When I pull the terminal from the solenoid the water stops. What has gone wrong now???

There is no belt on a front loader washing machine. The way the drum spins is by a stator in the back of the unit.

The front loader machine should be done by a appliance dealer because this is a diffuclt job and need a lot of patience if you do it. Hope this might help.

The door lock is the problem... try to push the door harder... or change the door lock! It is usually done in 5 minutes.. .... if it is only 5 months... you have a warrenty!

Its on the back of machine and after you remove the back cover plate youll see that its very easy to install the new one.You shouldnt have to use any tools to put on the new belt.Just loop it around the motor pulley and around the large tub pulley that you see right in front of you.It may even appear to be too tight while your winding it on the pulleys but its not .

If you stand in FRONT of the washer, leaning over the top, the drive wheel is underneath the main drive motor, on the RIGHT hand side.  Loop the belt over the drive motor wheel, then over the main pully, and it should be good to go!

If you have a face icon lit up the child lock is on, press and hold spin and rinse buttons until it goes off
