“`htmlCommon Symptoms & Causes
If your LG WT7300CW lid won’t lock, you’ll likely notice one or more of these telltale signs before or during a wash cycle.
- The washer displays an LE or dE error code on the control panel
- The wash cycle starts briefly then immediately stops or pauses
- You can hear the lid lock mechanism clicking repeatedly but the lid never engages
- The control panel shows “Lid Lock” indicator light flashing continuously
These issues are most commonly caused by a worn or failed lid lock assembly, a misaligned lid strike, or a faulty wiring harness connection between the lid lock and control board.
“`Safety First
- Unplug the washing machine from the power outlet before starting any repair — never work on a live appliance.
- Shut off the water supply valve before disconnecting any water lines or hoses.
- Wear work gloves when handling metal brackets, sheet metal edges, or sharp components.
- Take photos with your phone before disconnecting any wiring harnesses or connectors.
- Work in a well-lit area with enough floor space to lay removed panels flat.

Step-by-Step Repair Instructions
Step 1
Unplug the washer before doing anything — the lid lock is electrically activated and can shock you if power is live. Close the lid firmly and sight across both sides to confirm it sits flat with no visible gap; a warped or misaligned lid won’t depress the lock actuator, so the machine never receives the ‘lid closed’ signal and will refuse to start. If you see an uneven gap, the lid itself is the problem, not the lock.
Step 2
Locate the lid strike — the small plastic tab on the underside of the lid, toward the right rear — and inspect it for cracks or a clean break; this tab is what physically enters the lock assembly and triggers it, so a broken strike means the lock mechanism never engages regardless of how good the lock itself is. Replacement is straightforward: one screw holds the strike in place, and new strikes are inexpensive OEM parts. Pro tip: compare the broken strike to the new one before installing to confirm the tab geometry matches.
Step 3
To reach the lid lock assembly, open the lid and slide a putty knife along the front underside of the top panel to release the two spring clips, then hinge the panel up from the rear — do not yank it, as the wiring harness is still attached. Unplug the lid lock harness connector, then set your multimeter to Rx1 and probe the solenoid terminals; a functional solenoid reads near zero ohms, while an open reading (OL) confirms the solenoid has failed internally. This test tells you definitively whether the lock is the cause before you spend money on parts.
Step 4
With the top panel raised, open and close the lid slowly and watch both hinges — if the lid drops faster on one side or feels loose and wobbly, the hinge pivot is worn and the lid is no longer traveling in a straight, consistent path into the lock. A misaligned lid caused by a bad hinge will cause intermittent or complete lock failures even when all other components are good. Replace the hinge assembly using the two bolts per side, and support the lid so it doesn’t fall while you work.
Step 5
If the solenoid tested open in Step 3, replace the lid lock assembly — slide the old unit off its mounting tab, disconnect any remaining connectors, then snap the new assembly into place and reconnect the harness. Make sure the harness clicks firmly; a loose connector will cause the same ‘dL’ error you started with and send you chasing a problem that isn’t there. Use only an OEM or OEM-equivalent lock rated for the WT7300CW, as aftermarket tolerances on the strike opening can vary.
Step 6
Plug the washer back in and run a normal wash cycle, pressing Start and watching the lid — the lock should engage with an audible click within three seconds of pressing Start, and the ‘dL’ error code should not reappear on the display. If the lock engages but ‘dL’ persists, unplug and reseat the harness connector one more time, as the control board needs a clean signal from the lock switch to clear the fault. A persistent ‘dL’ after a confirmed good lock and solid connection points to a control board issue.

When to Call a Professional

Contact a licensed appliance technician — attempting sealed-system repairs without EPA 608 certification is illegal and unsafe.
