Question about LG WM3431 Front Load Washer / Dryer
When my washer wasn't drying properly I had to do two things.
1. Clean out the plastic opaque tube thing that goes from the top to the back (its about a foot and a half long). It builds up with lint and doesn't allow the air to flow. take a flashlight and shine it through and you should see the build up.
2. Clean out the heater fan motor on top of the machine. (this one could also cause the dhe error code).
Cleaning the plastic Tube thing...
There are about 8-12 hex/phillips screw that hold this thing together. You will need to remove the fan housing on top (you don't have to disconnect any wires, just un-mount it and rest it out of the way) and start to look for all the connections for the plastic tubing.(there are many that were hard to reach. keep this in mind as we go along) There is a rubber hose connection (compression connection) and a heating sensor (looks like a wire going into a rubber gasket) with a metal rod(about an inch long that you can't see until you pull it out) that you need to disconnect. You don't have the remove the rubber gasket, just pull the metal plate at the back of the gasket. Once you disconnect everything,(hoses, screws etc.) you should have the big plastic tube thing released. Go and clean it out. Now put it back the same way you took it off. Remember how I said to keep in mind all the screws and stuff...... I left two or three maybe more hard to reach screws off because you will be having to do this again in 6 months. (at least thats what I had to do.) try to use as many screws as possible because this thing shakes so much, but don't kill yourself. Also me careful not to over tighten the screws where there is just the plastic as it will crack and break off. You do not want that to happen. Just screw them tightly just not too tight.
Cleaning the fan motor....
this is the pieces that sits on top, it should be black chamber with a circular portion at the end. this is where the fan motor is. unscrew it and open it up. you should see a heat sensor (kind of like the one in plastic tube I mentioned above) at the front, a bunch of heating coils and the fan motor at the end. You will not be able to remove the fan from the motor itself (at least I couldn't) so you will just have to clean it as best as possible. Make it to the circular fan move as freely as possible. then just put everything back as normal....
I hope this helps.

Yes what you have to do is go to compact appliance.com. Then type in the model number.At the bottom of the page click the instalation tab and then click the service manual highlited area. Go to page 25 and it is in the condensing unit were the build of lint is located, this build up throws the sensors off. I did not have to replace any sensors, just had to clean it out and put it back together. Hope this helps if not let me know. Cheers

You need to find and replace the moisture sensor in the unit.
