Replacing the Door Boot Seal on an LG Front Load Washer
LG washer bellow gasket
Although the door gasket on LG washers is very similar to all the rest, that inner retaining spring seems to be just tight enough that it's worth the extra effort of removing the front panel to facilitate the installation. LG also makes two special spring pliers to help with removing and reinstalling the outer and inner retaining springs. Most Appliantologists say they can get by without the outer spring clamp tool Part number: AP4438623
but that inner spring clamp tool Part number: AP4439038
is worth the price of admission.
The other big thing to watch out for with getting the replacement LG door boot is to check to see if the model you're working on has the extra drain port at the 6 o'clock position or not. Sometimes, even looking up the door boot by model number will give you the wrong replacement boot and the presence or absence of the drain port seems to be the key difference.
Here's a video that shows how to replace the door boot using both the outer and inner spring clamp pliers and by removing the front panel of the machine.
