Although the lid is closed and the magnet attached to the lid is intact, the door open error message (dE) is displayed and the machine (LG fuzzy logic model no. T6515TDPT01) stops working after taking two /three turns in wash mode. I seek help from you guys to fix the problem. Thanks

Might be the magnet, usually the magnet pushes this switch the shows the door is closed. Hard to explain. Do you happen to have pictures?

Power off the machine and unplug it if you receive the error mid-cycle or at the end of the cycle. After five minutes, restart the machine and try to open the door again. Wait about a minute for the door to unlock if you paused the machine during a cycle. In this situation, the locked door and appearance of the DE error is merely a safety precaution.
