Question about LG WM0642H Front Load
I just repaired the same model washer. This washer has a direct drive stepping motor attached to a spline shaft on the rear of the drum. The hub on the rotor is made from fiberglass reinforced polyester plastic. The plastic spline socket on the hub fails. In my case, it spun free of the drum and overloaded the main board. I went to check on the load in the washer and found a completely dead control board and a soaking wet load inside. This machine is repair friendly and for the most part, durable.
Stop using it to prevent additional damage. If you are up to troubleshooting and repairing it yourself, it may only need a rotor. The repair requires a Philips screwdriver, 19mm and 10mm sockets on a 3/8" ratchet with 2" extension. A second pair of hands will be needed to hold the drum while you install the new rotor.
When you remove the rotor, inspect the inside surface of the magnets for scuffing. If there is any evidence of the magnets contacting the stator, its a good idea to remove the stator to inspect it for damage. Its possible for the rotor to scrape at the mounting points of the RPS and damage it. If the stator shows wear from contact with the rotor, replace it along with the RPS.

well , depending on where and when you pruchased the unit you should bve able to call the dealer and get a copy of the bill of sale, but as afar as your problem its quite possible that you havesoemthing stuck in you drain pump not allowing the water to drain and the machine will not spin without draining water first. in the lower left corner you ll find the drain acess, drain your water first then open that catch and look for foriegn debris.(i.e sock, screw/nail/ bra underwire)

You will need to replace the drain pump motor. The pump impeller has separated from the motor shaft. You can push it back on, but it will just come off again. I have not tried adding adhesive because I didn't want a call back. That may work if you want to try it. To replace pump motor:
Take the rectangular recess out by using a putty knife on the left or right side, Remove phillips screws mounting pump. Pull machine forward about two feet to allow you to tilt the machine back to lean it against the wall. Reach under to access the pump. It is held in place by a plastic tab you can depress to remove, but if you break the tab, don't worry, as the mounting screws will hold your pump in place just fine when reinstalled. Remove pump by disconnecting hoses and electrical plug. Change out pump motor (three phillips head screws)

"LE" code Stator/Motor Error.
It was a simple fix and only cost $17.68 at PartStore.com no affiliation.
Hall Sensor 6501KW2001A
Here is the Service Manual
Bonus, it actually completes a wash cycle and does not stick at 6 minutes, drying forever.
Freakin service tech stated it was the Power Control Board, IDIOT!
While I was in there, I cleaned out the heater blower assembly and sensors. They were full of caked on lint and the sensors had debris all over them.
Also cleaned out all the lint and debris around the rubber seal, this will eliminate those annoying mildew oders.
Hope this helps someone, Happy New Year!

I would guess that the impeller has come off the pump motor shaft. You can disassemble and push it back on, but it will come off again. I don't know if some type of adhesive would work, but I just replace the pump motor.
Drain water from small drain hose (or by removing filter) Remove the screw in the plastic recess by the filter, then use a putty knife on the left or right side to pop out the recess. Remove two more screws holding pump body to front frame of washer. Pull washer about 18 inches away from wall and tilt it back to lean against wall to allow access to the pump through the large rectangular hole in the base of the washer. There is a plastic locking tab holding the pump body to the plastic washer base, but don't worry if you break that, as the screws (removed earlier) will hold the pump back on just fine. Pump motor is held onto pump body with three more screws. Replace pump motor with a new one and reassemble. On a difficulty scale of 1 -10, this one might rate a 4.5 or a 5. Not too bad.
Leaking is rarely, if ever, caused by the drain pump. Small leaks can come from using too much soap, which backs up in the dispenser area and leaks down inside the machine, or larger leaks from a cut in the door gasket.
