Hi jerryleigers,

The Drain pump is working intermittently. It is either overheating or a loose wire is present or it could even just be a faulty drain pump. I'd suggest removing it (Found attached to the lower sump hose), testing it by aplying direct power to the 2 pins (either way is fine, it works on an alternating current), run it for 5 to 10 min (turning it on and off every 30 seconds), if it is fine then it is a worst case scenario (PCB). If it is not running well, or it is not even starting - replace it, problem solved.

Hope it helps :-)

SOURCE: My LG WM3431H All-In-One Washer and Dryer won't dry

Thanks to CoolTech for pointing me in the right direction, I just finished a full clean out and diagnostics test and my dryer works once again.

This repair isn't rocket science nor is it a good idea for the mechanically timid. I managed to get the critical parts out for cleaning and back in properly with just a phillips head screwdriver and a pair of pliers for the spring type hose clamps so it's not a matter of custom tools.

You have dig pretty deep and remove an awful lot of cabinet parts, fans, heater assemblies and something like 30 or 40 various screws to get to the condensor duct and bellows to clean them. Sure enough my condensor duct was jam packed with lint. Once removed I was able to clean it with a creatively bent coat hanger, but a semi flexible bottle brush/pipe cleaner about 18 inches long and an inch or so brush diameter would be a better tool.

If you want to tackle this job, and again it sounds daunting but isn't to someone with reasonable mechanical skills you should do yourself a favor and buy a copy of the factory service manual. I got mine on line from these guys: http://www.manualuniverse.com/ but there are probably other sources including LG if you search by the model number.

In addition to some less than obvious disassembly instructions the manual tells you how to trigger the self test mode and how to interpret the results, gives you good information on cold state resistance tests you can do on relays, heater elements, sensors, etc. and provides a good troubleshooting guide for a variety of problems.

All in all the job took me about an hour and a half and was pretty straightforward except for the last mounting screw for the condensor duct which is hard to get to and requires some effort to remove and replace but again I did the whole job with a standard medium sized screwdriver so it's not impossible.

Good luck and if you're having this problem and like me you don't have any local repair folks who'll touch it (not many of these all in ones in Wyoming) then I'd get your hands on the manual and dig into it. It's not fun, but not too hard either.

SOURCE: LG WM2487 front load washer spews suds out of port on rear.

You are likely using too much detergent or the detergent is not high-efficiency detergent. Change detergents and/or lower amount and this problem should go away.

The water port on the back allows air inside the tub to escape. However, if the wrong type or quantity of detergent are used, excess suds will flow from this port.

Hoover elite 700 washing machine won't spin


There are several reasons that a washing machine won't drain or spin. The cause could be something as easy as a clog or something difficult that will need a licensed repairman. Start with the simplest possible cause and work down to the more difficult causes.

INSTRUCTION BELOW
# A washing machine won't spin if the water can't drain. Check hoses for any kinks or clogs that may prevent the water from draining. If a hose has kinks, try to straighten out the kinked hose. If it can't be straighten sufficiently, replace the hose. If hoses are not kinked, check for clogged hoses. This can be done by using the screwdrivers to remove the hoses and looking for clogs or running a water hose through the clogged hose to remove the clog. Use the rags and bucket to clean up the water that comes out of the hoses when they are disconnected. Once the clog is cleared, put the drain hose back into place. The washer should drain and spin now if a clogged or kinked hose was the problem.
# 2 If the washer still won't drain or spin, check to see if the lid is not closing all the way or if the lid switch is not clicking into place. Close the lid and make sure that it closes all the way down. When the lid closes, the lid switch should click. If there is no clicking sound, then the switch may need to be replaced. Follow manufacturer's directions for replacing the switch. If the lid does not close all the way, visually check for signs that the lid is bent. If bent, try to bend it back into place.
# 3 Loose or broken belts could also prevent a washing machine from draining or spinning. Pull the washer away from the wall and, using the screwdrivers and wrenches, remove the back panel. Using the flashlight, visually check for any broken or loose belts. Replace any broken or loose belts. Although replacing washing machine belts is difficult, anyone who has replaced belts on a car, lawn mower or even a bicycle chain should be able to accomplish the task.
# 4 Another possibility for a washing machine to not spin or drain is the pump. With the back panel still off the washer, check the pump with the voltmeter to ensure that the pump is getting power. If the washer is getting power, turn on the washer and listen to find out if the pump is running but the water is still not draining. It may be necessary to remove the pump and clean it or to replace the pump with a new one. Once the pump is replaced, turn on the washer to determine if it will now drain and spin.
# 5 If all of the above steps fail to produce a washing machine that drains or spins, then it is time to call a professional repairman. Use the screwdrivers and wrenches to replace the panel on the washer and push it back against the wall

Regards.

My lg washer and dryer wm3431hs isn't draining. I took of the hoses in the back, cleaned the filters and still nothing please help!


Hi

If the washer is not draining then it is due to a clogged drain pump or a drain filter or a kinked drain hose. To resolve the issue you'll need to clean the drain hose, inspect if the drain hose is plugged. If the hose is fine, then remove the front kick panel and access the drain pump and filter, if you are unable to find the pump and filter remove the back panel as well and trace the drain hose to the bottom of the tub. There is a drain filter connected with the drain pump. It usually gets clogged, and needs to be cleaned every 6-8 months or so. The drain filter is a small white filter connected to drain pump with a hose. If it still doesn't work then you'll need to check the connections of the drain pump, check the electrical connections with a multimeter. If it still doesn't work then you would need to replace the drain pump. Hope this helps...

LG Washer/Dryer won't drain


The LG error code OE simply means "the pump is blocked". Presumably the water isn't being emptied properly. As with all error codes it is possible that there is a cause other than the exact description in the error code explanation but basically this error means as far as the washing machine is concerned it thinks the water isn't pumping out. A pump, or filter blockage is the most common cause but it could be caused by other faults such as a faulty pump, or even a blockage in the drain hose or somewhere else in the system etc.


LG themselves have some information on this error code..

My lg #wm3431hs making strange noise and wont drain


If your washer won't drain, check these:

It spins, but doesn't pump 
It doesn't spin or pump
It pumps, but the water returns
It spins, but doesn't pump If your washer spins but doesn't pump the water out, the drain line is probably clogged. In many washers, a small sock or other piece of clothing can get between the clothes tub and the outer tub that holds the water. If the clothing gets between the tubs, it may then get into the drain hose that's attached to the pump--or even into the pump itself. If it's in the pump, you need to remove the hoses from the pump and pull the item out.

To remove the sock from the outer tub port, open the washer's main access panel and remove the large-diameter rubber hose that connects the pump to the bottom of the outer tub. Then, using needle-nose pliers, try to grab and remove the clothing through the port. 

Sometimes you can't remove the stuck clothing from below. Then you have to remove the agitator, top of the outer drum shield, and inner clothes tub. This isn't easy to do--and you may need special tools--so you might be happier getting a qualified appliance repair technician to do the job.

If the drain line isn't plugged, the problem may be with your pump. Even if the pump appears to be turning, the internal impeller may be broken. If so, you need to replace the pump.

It doesn't spin or pump If your washer doesn't spin or pump water out but the motor is running, your washer probably has a frozen pump pulley. If so, you need to replace the pump. To check the pulley, remove the pump from the washer and try to rotate the pulley manually. If it doesn't turn freely--if it's frozen or stiff--replace it. 

It pumps, but the water returns If the water that pumps out of the machine goes back into the machine after the spin cycle, your washer may be siphoning the water from a laundry tub that has a slow drain, back into the washer. The usual remedy for this is to improve the draining of the laundry tub. (Is something stuck in the drain?) Also, check for these problems:

  • If the drain hose reaches more than about 4 inches into the laundry tub, cut off the excess.


  • If your drain hose is lower than the washer's cabinet, install an air gap/siphon break assembly.

LG WM3431H Washer/Dryer won't start


If you are sure the unit is receiving power you can check for proper operation the door switch on unit which will kill power to unit if it is open. If it is ok, using a voltmeter you will need to trace the voltage at the control switch, etc.
