Error code is de what can i do? - Samsung Washing Machines

Means Drainage Error. You need to clear out the drain pump. Depends if its a top loader or front loader. If front then if you should be able to access the pump from the front bottom by unscrewing and removing the filter. If not then you will need to tilt the machine back as far as you can so you can access the underneath. You will see the small drain pump. Have a basin ready to catch any water that comes out when remove the pump which is only held in by 1 or 2 screws and twisted out or pulled out. If it is clear then try removing the pipe that goes from the pump to the base of the tub. Hope this helps
