Question about LG WM3431 Front Load Washer / Dryer
Fills with water but wash cycle does not start
No agitation or spin? try these:
WATER PRESSURE SWITCH: This switch keeps your washer from overflowing. It is responsible for shutting off the power to the fill valve and redirects the power to the timer to start the washing machine running once the correct water level has been reached. Meter check ur water pressure switch?
You can test it with a meter and with a manual test? ( first locate it in the panel, it has a plastic clear tube hose going into it, remove that tube from its connection, now put another small tube or hose into the slot where it was and have the machine set to wash cycle with water in it. Blow into the other end of the tube.
If the machine starts to wash. the pressure switch is more than likely good
( No wash starts - then THE DIAPHRAGM IS BAD AND SWITCH HAS TO BE REPLACED) another test u can do is Remove the hose and submerge in water. Seal one end and blow air into the other end and look for bubbles. Check for an obstruction in the hose as well.
Or take the original hose tube and plug one end and blow into it AT the other end, it should be hard and have pressure, if it is easy to blow and u dont feel any pressure and it feels like the air is going out ?
Sometimes they get busted open or a pin hole and release air causing the water switch diaphragm to not open.
Motor Coupling If the washer won't spin or agitate the motor coupling might have failed. The motor coupling connects the motor to the washer transmission. It is designed to fail if the washer is overloaded in order to protect both the motor and
Drive Belt If the washer won't spin or agitate, check the drive belt. If the belt is broken or if it isn't tight on the pulleys the washer won't spin or agitate properly.
Drive Motor If the washer won't spin or agitate the drive motor might be defective. This is not common. Check all of the other related parts to this symptom before replacing the motor. If the motor is visibly burned out or physically damaged, replace it.
Stator Assembly If the washer won't spin or agitate the stator assembly might be burned out. The stator is essentially one half of a motor, it interacts with the tub by creating a strong electro-magnet. If the stator burns out the washer won't spin or agitate. Check the stator for continuity. This part is often misdiagnosed.
Transmission or clutch assembly not engaging due to going out or slipping.
Door or Lid Latch Assembly If the washer won't spin or agitate the lid switch assembly might be defective. This is a very common problem. The lid switch assembly can fail either mechanically or electrically. Test any electrical switches with an Ohm meter for continuity. The switches should have continuity according to their design.
Door Lock Motor and Switch Assembly If the washer won't spin or agitate the door lock assembly should be checked. The door lock can fail either mechanically or electrically. Test any switches on the door lock with an Ohm meter. The switches should have continuity according to their design.
Motor Control Board If the washer won't spin or agitate the motor control board might be defective. The motor control board provides power to the motor as well as direction and force. If the motor control board is defective the washer may not work at all or function properly.
CHECK THE CAM DOGS INSIDE THE AGITATOR, AS THEY WILL HINDER THE AGITATION PROCESS. However in G.E models the cam dogs are replaced with what is called an agitator coupler. (located at bottom of tub)
Remember to check the agitator spline as well for worn broken teeth.

Hard call, double check the outlet to make sure it is good, take off the top lid. 2 screws at the back then push it back.
Check to see if you have voltage once the line has gone through the noise filter. If no power there, you have a bad filter. If you have filter, see if you can see a red led light on the main board. no then it is a bad board. If there is a light then then check to make sure it is not a loose connection.. Make sure all your connections are good to the front display.
After all that, if it still isn't working then it goes back to the main board.
tricky one there.

If your washer fills with water, usually slowly, after the cycle is over you have a inlet water valve which is not shutting off completely. LG usually uses a separate valve for the hot and cold. If you turn off the valve where the hose comes from the house and observe for continued water fill, first one, the reopen it, then shut off the other you should be able to see which (hot or cold) is the culprit. If you post your exact model number I should be able to list the part numbers for you. The inlet valves I am speaking of are the part where the hoses connect onto your machine.

First try unplugging the machine for a few minutes and then retry a cycle. If you still get the LE error:
The Hall sensor (part number 6501KW2001A) has failed. The hall sensor is rather easy to replace, and is covered by a seven year part warranty (in the US). Take the back cover off. Take the big nut off and remove the motor rotor. Remove the bolts holding the motor windings. Remove the electric plug on the sensor and unclip it from the motor winding. Snap new sensor on and reassemble. Usually takes under a half hour. On a difficulty scale of 1 - 10, it might rate a 4. This should be a Fix-Ya for your machine, and at basically no cost!

The problem with this one is I'm not there but, without having the tech sheet for this model I would assume DE means "door error" or a drain problem. I believe this model has a clean out drain in it. Remove the bottom panel or there maybe a panel that just pops off. It won't spin if it can't drain. Unscrew the drain (have some towels or a bucket ready)(UNPLUG MACHINE)...If it's clogged then that's the problem. If it's the door it could be the lock assembly or the control board itself. This is why it makes it hard to do without being there. There are three boards in this unit...Hope I've helped a little.
