LG washing machine flooded the Landry room.
Wife called me and said the washing machine just flooded the Landry room. I looked at it and didn't see anything wrong. Took the top off and the back off and started looking for a leak, did not see anything. Took the front part of the washer apart thinking the drain hole was plugged up where the rubber boot is. It was ok after taking the big rubber boot off or whatever that is called i was not getting anywhere. I put it back together left the top and the back off. I turned the water on and started the washer on a quick cycle looking for a leak. I found the bellows at the inlet had a small leak fixed that and started the washer again. So what i found out was the clean out drain plug was not in tight letting water out as it was washing after i tightened it all was ok. So i did find a leak that was small that we never saw. The hardest part was putting that wire clamp on the rubber boot it took two people to do that.

Washer did not recognize the door was shut
I removed the Wire and spring from the tub seal and then removed the seal on the side of the washer that contains the Door switch. I removed the two screws that held the door switch in place while holding the switch with my other hand. Once the screws where out I pulled the switch assembly out thru the gap and removed the wires from old assembly. I then plugged the wires into the new assembly aligned the holes up and put the screws back in the new door switch assembly. I then put the door seal and tub seal holder back on. This took about 15 minutes. I do recomend that you unplug the washer before starting this process.

Leaking hose
2 hose clamps and a hose, easy! This would be a very common cause of leaks in washers due to all the movement inside.

Leak in top washer hose
Super straightforward to diagnose and repair.

There was puddle under the washer.

I removed the top (screws in rear, slide top toward rear slightly and lift) and followed the trail of water up to the top washer hose between the drum and detergent tray.

Two hose clamps to remove and replace, then replace the top and ready to go.

Water inlet valve relacement
Installed correctly but PartsSelect sent WRONG part, but part number on bag was correct. Installation of WRONG part fried the main board. A $100 fix is now costing me about $1300.00 for technician service and new unit. I asked PartsSelect to help with cost since outcome is due to their error. Totally unsatisfied. Will not suggest company to other DIYers.

Noticed small tear in hose bellows and leak during reassembly
I already had the top of the washer open, from previous disassembly to clean the front loader seal, and when I ran a trial load, noticed a small 1/4" tear in the hose bellows that attaches to the drum.

Very simple repair, remove the existing hose by loosening the clamps, paying attention to their orientation. Install the existing hose clamps onto the new hose, install and tighten the hose clamps.

5 minute job, if the washer top is off (which is also simple).

The tub-to-pump hose was leaking.
I tipped the right side of the washer up 9.5 inches using two 2x4s and I was able to remove and replace the old hose with the tools described.

Pool of water under washer after a run
Did the repair entirely from the back.- 4 screws back cover comes off. Once you see the Bellows it is obvious what needs to come off and there are other videos on the net showing this. The main things I did differently were 1) Leaned the washer forward and placed 3 2x4 blocks of wood under each back leg. This allowed me to reach under the washer with one hand, and through the back with the other. You need both hands in there ! 2) Uninstalling is easy with just pliers. But on the way back in, I used a pair of Locking Pliers to keep the circular clamp squeezed as much as possible. That seemed the only way to get the bellows back in. Another option would be to switch to screw on Pipe clamps instead of the spring clamps.

Hole worn in bellows over time
UNPLUG WASHER.Unscrew 4 screws holding silver plate at back of unit. Remove plate to expose inside of unit. Locate drain hose at bottom of washer tub. Hose connects at front drain, bottom of tub, and at rear at the pressure sensor. Front and rear simply slide clamps down by grasping clamp tabs and sliding clamp off connection point. Disconnect from tub bottom by loosening main clamp with Phillips screwdriver and pulling downward. Have a towel handy as there will be water in the hose, and it will pour out when removing it from the unit. Installation is the reverse of removal. ATTACH THE HOSE ASSEMBLY TO THE DRUM FIRST, THEN FRONT, THEN LASTLY REAR. This order is the easiest way, otherwise you will spend extra minutes trying to get the tub connection to seat properly. Plug it back in (duh), then you're good to go for another 4 years or so until another hole wears in the hose. I have performed this repair on 3 different units, with 4 years being the average lifespan of this part.

Washing machine was leaking
Contacted LG customer service, not much help there. Watched a very helpful Utube video on how to find and repair the leak. The video suggested that the most common leak is in the drain hose with bellows. Removed the rear panel and removed the bellows unit using pliers for the clamps and screwdriver for the bellows part. This was pretty easy. The rubber bellows was leaking in the exact same place as the youtube video showed. This is a Design Flaw that LG needs to fix. Ordered the new part and installed the bellows portion of the part first, as the angle for that installation needs to be correct. Then attempted to install the end of the hose (very inaccesible) to the pump drain. Very difficult to position the factory supplied spring clamp with pliers so I purchased a screw-type clamp (using the nut-driver rather than a screw-driver to tighten the clamp was helpful) at the local hardware store and that made my job much easier. Note: My unit is mounted on a pedestal, so it was a little easier to access the part location (about one foot off the floor, rather than at floor level), but it may be that the part should be replaced from the bottom of the unit, which would make it much easier to access. Then I installed the other end of the hose to the drain line using a screw-type clamp. I am 69 years old, and not that flexible anymore, so getting down on the floor to reach inside the unit was difficult. You need patience to do this job and you have to make sure all the clamps are properly installed so you don't start the machine up and end up with another leak. For me, this process was difficult and took more than two hours to complete. Limited access to the area made it more difficult and I hate the factory clamps they use. Overall, the repair costs about $25, compared to the $125 just to come look at the machine, then more money to fix the unit. It was satisfying to complete the repair for a small amount of money, but not sure it was worth the aggravation.
