Understanding the Problem
Brief explanation: Many LG (and similar) top-load washers display "DL" (door lock) or a stuck lock/error related to the lid lock assembly. The DL switch (lid/door lock) tells the control board whether the lid is closed and locked; if it fails the washer may not start, may show DL error codes, or may not spin/lock properly. Step-by-step diagnostic and repair steps: 1) Confirm the symptom and error code: - Note the exact symptom: washer won’t start, won’t spin, shows "DL" or "door" on display, or intermittently locks/unlocks. - If you see a blinking or error code, write it down — DL usually points to lid lock-related issues. 2) Basic resets and checks: - Unplug the washer for 1 minute, then plug back in and try a cycle. Sometimes the control needs a reset. - Make sure the lid closes fully and the strike/latch isn’t obstructed. 3) Inspect the lid/latch area visually: - Open the lid and look at the lock assembly for cracked plastic, broken striker, or melted parts. - Check the lid strike (on the lid) and the lock housing (on the cabinet/top) for physical damage. 4) Test the lid switch electrically (requires a multimeter): - Unplug the washer. - Access the lid lock/switch (usually under the control console or along the top rim). Remove the necessary screws to gain access. - Locate the two- or three-wire connector from the lock to the harness and disconnect it. - Set your multimeter to continuity or Ohms. - With the lock in its resting/unlocked position, test the switch pins for continuity per the service manual (many lid locks will show open circuit when unlocked and closed when locked). If continuity does not change when you manually actuate the lock, the switch is bad. 5) Check wiring and connections: - Inspect the harness and connector for burned, corroded, or loose pins. Wiggle the wiring while observing the display; intermittent faults often come from wiring damage. - Measure voltage at the connector when the washer is powered and trying to lock (only if you are comfortable and experienced with live voltage testing). If the control is not supplying the locking voltage, the issue may be the control board. 6) Replace the lid/door lock assembly if defective: - Order the correct replacement part for WT7200C (see parts list below). - Follow the replacement steps below. 7) Final test: - Reconnect power, run a short diagnostic or quick cycle and confirm the DL code is gone and the lid locks/unlocks and the washer completes the spin/drain steps. Basic replacement steps (how to fix): 1) Unplug the washer from power and turn off the water (safety first). 2) Remove the control console/top if needed: on many top-load models this involves removing screws at the back of the console, tilting it up, and securing it so you can work under it. 3) Locate the lid lock assembly along the top rim or under the control console. Disconnect the wiring harness connector(s). 4) Remove the mounting screws that hold the lock assembly in place, and pull the old assembly out through the opening. 5) Install the new lid lock assembly into the opening, secure with mounting screws, and reconnect the wiring harness. Make sure the connector seats fully and locks. 6) Reassemble the console/top, restore the lid striker if it was removed, and plug the washer back in. 7) Run a test cycle to verify the locker engages and the DL error is resolved. Safety note: Always unplug the washer before doing any internal checks or disconnecting electrical connectors. If you are not comfortable working around live voltage, call a qualified technician.
Common Symptoms
Washer shows "DL" or "door" error, won't start or spin, lid lock light stays on or flashes, intermittent locking/unlocking, or physical damage at the lid lock.
Common Causes
- Failed lid/door lock switch (internal electrical failure)
- Broken or misaligned lid striker or lock housing (mechanical failure)
- Damaged wiring harness or loose connector between lock and control board
- Control board failing to send lock/unlock voltage (less common)

Helpful Repair Tip
If you manually depress or move the lock mechanism and the washer starts/resumes a cycle, the lid switch is almost certainly the culprit—test continuity to confirm.
Frequently Asked Questions
My washer shows DL but the lid looks fine. Could it still be the lock?
Yes. The DL error can come from an internal electrical failure inside the lid lock; visually the lock can look OK while the switch contacts fail. Test for continuity or replace the lock assembly if wiring and connectors check out.
Can I bypass the DL switch to make the washer run?
You might be able to force the washer to run by bypassing the switch, but this is not recommended because the lid lock is a safety device. Bypassing can create a risk of injury and may void warranties. Replace the faulty lock assembly for a safe, permanent fix.
