Not enough water

there is a small pipe that runs from the drum buttom to the diafragma sensor water level
(it's a round thing 5" at the highst point in the machin) this item close a sircet and close the water inlet.
please chace for cracks or blocks in this pipe
all rhe best

The problem would appear to be the water inlet solenoid valve.
The valve is not operating correctly for some reason allowing water into the machine even when switched off

tE is a thermister error. It is a temperature sensor at the bottom front of the washer. tE can also be caused by a heater error. Some models have a seperate thermister, some incorporate it with the heater. It is very difficult to replace without taking the front off the machine.

FE Over Flow Error

Water is overflowing (water level frequency is over 213).

If FE is displayed, the drain pump will operate to drain the water automatically.

(may be too much suds ...)

WM2277HW Service Manual HERE...

Or

Locate your service manual behind the kick panel of the machine.

FE means overflow condition.

Before replacing the fill valve sand or trash may have gotten into the tube going from tub to water level switch.

So find that hose and blow it out. Remove the standing water and retry.

Thanks for using FixYa!

I have give the same solution in other post, here it is : 
usually problem with semi auto washing machine is on the sensors , exactly in the water level sensor, please check the hose that connected to water level sensor, make sure no dirt blocking or clogging the hose. also you can clean the tube under the pulsator, usually there is many dirt blocking the hose line.
the problem is in the hose leading to the water level sensor, if there is no dirt and looks normal, water level sensor must be replaced

Check your water frequency level it is below 26 you will get the inlet error. Here is something you can try:
When you press the "SPIN SPEED" button and "SOIL LEVEL" button the water level frequency should be above 246. If it is below that number remove the top; find the small tube going to the main control on the backside and blow it out. Get rid of the sediment and reconnect tightly. Pump out water and retry.

This is normal.
All LG washers use a siphon system to dispense soap, bleach and fabric softner.
Some times water will remain in the cups depending on the cycle used.

Starting in November 2008--LG introduced "square door" model washers.
These washers will (unlike round door models) perform very well on wood floors.
If the WM2487 washer is on a wood floor--even a tiled wood floor--it will be near impossible to get smooth spin performance.
Some homeowners have had success by adding two layers of 3/4 inch wood under the washer AND dryer.
The following steps were taken:
1) Remove washer & dryer
2) Cut & remove any floor covering (bare wood)
3) Locate floor joists with a stud-finder & mark locations at the edge of the flooring--allows finding the joist locations after 3/4 sheet is laid to floor.
4) Add wood glue to floor
5) Place 3/4 inch wood sheet to floor & drive screws thru wood into joists (as many scews as deemed necessary to fully & completely compress wood sheet to existing floor
6) Add wood glue to 1st wood sheet
7) Place 2nd 3/4 inch wood sheet on top of 1st wood layer and drive screws into floor joists.
8) Add molding if desired
9) Re-install washer & dryer and level.
10) Add one heavy towel into washer tub & close door ( this will mimick an off-center load)
11) Press power "on" button
12) Press "Spin Speed" button & select high speed spin option
13) Press "Start" button
14) When * 9 minutes remaining * is displayed--use the flat wrenchette that comes with every LG washer to "tweak" the adjustment of the front leveling legs. This will allow for "fine tuning" adjustment of the front leveling leg(s) to eliminate vibration / noise during the spin cycle. The rear leveling legs DO NOT need further adjustment.
NOTE: Those with pedestals--check the front leveling legs on the washer and on the pedestals (front only) during spin.

No. Water level is not user adjustable. The washer will automatically put in the correct amount (about 3 inches in the bottom of the tub) and adjust for load size and type. This level is all that is needed. The reason the clothes are hardly wet at the end of the cycle is due to the high spin speed (compared to almost all top loading machines). If you want to see how wet the clothes really are, pause the machine mid cycle and the door will unlock and you can see, or select a "no spin" option and see at the end of that cycle. You will use about 12 gallons of water for a large load, vs. about 45 for a top loading machine, so remember to adjust your soap and fabric softener use accordingly. ( one tablespoon detergent and one teaspoon fabric softener maximum per load)

Check that the drain hose is not clogged.
Access to the drain pump and check the drain pump intake, that is probably filled with debris.
Ensure that the drain pump is working, the pump should be energized directly by a technician to test it.

If the drain pump is fine , and you already tested water level switch, then it is either a bad control board, or a lose contact on the drain pump wiring harness to control.
