Product review (5 stars): Does the job!
My story is the same as that of others that have reviewed here. We saw water on the floor around our LG front-loading washer. We'd just washed a large comforter, and sometimes those things soak up a lot of water and get heavy and throw things off a bit so I figured it was just a temporary thing. But as water continued to leak I figured it was time to take a look inside the machine.

Getting into the machine is pretty easy:
- use a Phillips head screwdriver to remove the screws from the washer's lid (two screws at the upper back)
- slide the washer lid back a bit and then you'll be able to pull it up and off the washer

Verify the water leak is coming from the valve. The valve should be wet. You might see water filling up at the hole at the top depending on how the valve broke. That's what was happening in my washer. Did a little searching and found this baby on Amazon for cheap.

The repair will take you all of 15 minutes, if that. Here's what I did (apologies for the mansplaining, but maybe it'll help the uninitiated):
- unplug the washer from electricity
- turn off the water to the machine
- unscrew the hot water hose from faulty valve's connector at the back of the washer
- use the Phillips screwdriver to unfasten the faulty valve's screws from the rear of the washer
- pull the electric connector off the faulty valve
- use pliers to open the interior hot water line clamp and slide it down the hose a bit away from the faulty valve
- pull the hot water line off the faulty valve
- the faulty valve should now be free of any connection to the washer and you can remove and dispose of it
- reverse the steps to install the new valve (connect the interior water line and its hose clamp, affix the electric connector on the new valve, screw the new valve onto the back of the washer, put the washer lid back on, reconnect the exterior hot water hose, turn the water back on, plug the washer back in)

You can also probably find videos on valve replacement that will help.

I have no idea what a plumber or appliance repair person would charge for this but if you can do it yourself it's a cheap and easy fix. I wish they were all this way! Thanks to LG and Amazon.
