The DE error is displayed in the middle of a washing, rinsing or spin cycles. The smell of burning is in the air, the indicator “Lock” may light. The control board malfunctions. Check the element. If damaged, clean the connectors and solder the contacts. If the board is beyond repair, replace it.

The door of the LG washing machine will not close due to the old hinges. The hinge is damaged. If you can not adjust it, then replace the part.

If you have made all the above mentioned steps and the DE error is still with you, use the following algorithm to detect malfunction.  The algorithm was developed by the professionals. It suggests initial testing the lock assembly. How to do it?

Consider the reasons of malfunction to clear the error. If you are confident the locks work properly, examine the small board. It is located in the control module and switches the LG washing machine on and off.

  1. First remove the plastic lid covering the control board, gently prying off a few plastic retaining clips with a screwdriver.
  2. Next, unscrew a few screws holding the control board.
  3. The board consists of two parts: a large board with a display and a small board switching the washing machine on and off. We need just the small board.
  4. Remove the large board and put it aside.
  5. Examine the small board for any visible damage (burnouts, damaged contacts, and other things) carefully.
  6. If it is damaged, then it is the cause of the DE error, and we shall handle it. If it is not damaged, contact the experts.

Having reinstalled the board, check if the machine works properly. If the error is not displayed and the LG machine works fine, you did the right thing.
