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.
