Washer Door Won't Latch or Won't Start? Door Lock 6601ER1004C – Fix dE / LE Error Codes Fast

If your LG front-load washer won't start, shows a dE or LE door error code, or the door won't latch or unlock after a cycle, the door lock assembly is the most likely cause. In LG front-load washers, the 6601ER1004C door lock assembly both latches the door mechanically and sends a signal to the control board confirming the door is secured — when it fails, the washer refuses to start or gets stuck mid-cycle with the door locked. ⚡ One of the most common failure points in LG front-load washers. Part 6601ER1004C is the genuine OEM replacement that restores proper door latching and cycle operation immediately.

❓ Is This the Right Part?

This is the correct fix if ALL of the following are true:

• ✔ Washer powers on and control panel is responsive
• ✔ Water supply is connected and inlet valve is confirmed functional
• ✔ Door hinge and door boot seal are intact — door closes fully but won't latch or signal
• ✔ ONLY problem is door won't latch, washer won't start, or dE/LE error code displayed
