The short answer
On an LG washer the door complaint usually starts with the load. A drum filled to the glass traps fabric at the boot, which both opens a water path and holds the door a fraction off its lock. Rule that out with one smaller load first, then look at the boot fold, the strike and only finally the lock itself.
Causes, ranked for this Lg washer
- Overloading trapping fabric at the boot — Why: A drum filled to the glass leaves nowhere for a sleeve to go but into the seal, which opens a water path and holds the door off its lock with nothing damaged.
- Boot cut or perished at its lower fold — Why: Coins and underwires collect in the deep fold at the bottom instead of washing away and eventually cut through, so the leak appears only on high-fill cycles.
- Door strike worn or deformed — Why: The strike takes the full closing force of a heavy glass door at every use and rounds slowly, so the lock stops confirming while the door still feels shut.
- Retaining band displaced — Why: The outer band can sit out of its groove after a repair or a very heavy load, letting the boot lip lift; it mimics a tear exactly and costs nothing to correct.
- Door lock assembly or its harness — Why: Last, because the mechanical causes explain the same symptoms far more often, and the lock wiring runs through a flexing hinge loom that needs metering.
What to check, in order
- run one deliberately smaller load and see whether the complaint disappears. — Because: it is the top cause and one cycle settles it for nothing.
- peel the boot fold back all the way round and clear it. — Because: the leak lives here and the debris you remove is what would cut it next.
- inspect the strike and watch it enter the lock as you close the door. — Because: a rounded strike explains a repeated click without any electrical fault.
- check the retaining band is seated all the way round. — Because: a displaced band imitates a tear and is refitted without a part.
Checks you can safely do yourself
- Unplug the machine, open the door fully and check the boot all round for fabric trapped from the previous cycle. — Tools: none — Time: a minute
- Peel the boot back from the drum lip, clear the fold of coins, wires and lint, dry it and feel for splits along the bottom. — Tools: a torch and a cloth — Time: several minutes
- Inspect the plastic strike for rounding, cracks or a split at its base, and look into the lock pocket for debris. — Tools: a torch — Time: several minutes
- Check the outer retaining band sits fully in its groove all the way round, refitting it if it has lifted. — Tools: a torch — Time: several minutes
- Run a half load and note whether the leak or the lock complaint recurs. Stop here: metering the lock is service work. — Tools: none — Time: the better part of an hour, mostly waiting
Before you open anything
Safety
unplug-before-service
The door lock is the interlock that stops the drum turning with the door open, and it must never be defeated with a magnet, screwdriver or tape. Do not force a locked door after a cycle, since it releases on its own schedule. Unplug the machine before inspecting the lock pocket, and drain the drum first.
Where the owner fix ends
Reducing load size, clearing the boot fold, reseating the band and inspecting the strike are owner work. Call a technician when the strike is sound and the machine still reports an open door, since the lock circuit must be metered live; and when the boot is cut, because the retaining band and front panel must come off.
