Question about LG WM3431 Front Load Washer / Dryer

Error code dHE

Hello - Just purchased and installed this all in one. No problems with wash, rinse, spin, but as dry cycle begins, the machine displays error code dHE. According to the manual, users should check water supply to confirm water is on. Of course, it is on at this point since it just went throught the wash. Manual says to unplug and see if error goes away. It doesn't. Why does this machine need water on a dry cycle? Any ideas? Thanks in advance!

Model:LG WM3431HW
Problem: DHE Error
Solution: Cleaned the fan motor mechanism

All the post were helpful and I was able to fix my problem so I thought I'd share.....

Once I got the error I tried what the users manual suggested(check water supply/unplug/plug back in) and nothing fixed it. When I opened up the machine I went straight for the fan motor and that was it. The fan is a circular type and it was caked on with lint. Long story short it was not turning due to all the lint build up. I cleaned it up and made sure that it was spinning freely. I put it all back together and it seems to be working fine..... I hope this helped and I wanted to say thanks to the other poster's.

Several reports in Australia of brand new LG Washer/Dryer combo (model number WD14700RD) getting dHE error's with very 1st dry cycle.
I bought a LG WD14700RD last week, and yup, washed fine.

Dryer cycle results in dHE error.
Everytime.
Cycle stops & you just have to power off the machine.

Service man found several possible causes.
He unscrewed the top of the machine off & said dHE errors are related to the dryer components. He started a dryer cycle & watched & lisened to machine.
He observed the dryer fan was not starting up.
He unplugged the power cable to the dryer & replugged.
The fan now started up, but only with cold air.
He then looked towards the front of the machine & noticed several cables had come loose from their sockets, one he identified was the heater element cable.
He plugged that back in & another unknown cable was also loose. He plugged that back in.
It worked.
dHE error gone & dryer fan started & pumped out hot air.

It seems at least a few of these machines during transit (from South Korea?) fail due to cables coming loose from their sockets.
dHE errors result if fan cable & fan heating element cable come loose.
My thanks to WAM electrical repairs in Box Hill (Melbourne) for helpfull advice & successfull repair.
For people looking at buying this machine, it washes & now dries perfectly well & I am happy with the machine.
But beware that this problem is out there (there are several other reports I read) and it have this problem, which is easily fixed but does require a service call out, under warranty of course.

I hope this helps, I had the DHE indicator no longer than 5 seconds after selecting the dry only cycle and the machine would stop.

My Fix: used a drill w/ phillips head drill bit and removed the entire top of the machine (this will expose all the components). Then I took apart the cover to the heating element and found all types of old lint deposits. I also took apart the fan cover and found lots there as well and cleaned it out. Then I noticed the plastic container/pathway that the fan is supposed to push the hot air through congested and cleaned it as best as I could as well. Afterwards, I put it all back together and that seemed to have fixed the problem.

I hope this helps, my suspect that, as a safety mechanism, the pathway and etc.. was cluttered so the heat was backing back up and there must be some temperature gauge or some type of way to indicate this is happenging.

Note: I am not a fix it guy, I never took anything on a washer or dryer, my warranty was expired so I figured, if I call a repair guy, it might as well be worth it :)

Good Luck with YaFix!

Code dhe. Take 2 screws from rear of the top.slide top towards rear to take it off. Take off the metal shield Below that . You'll see a fan motor assembly take that apart plus the heater cover in front of that also take an air intake off as well below the fan motor( will need to take rear sheet metal cover 4 screws and take additional 5 screws out of that air intake that's the real problem it will be filled with lint once you take it out just rinse it out put everything back together and it should work. Don't forget to clean the motor blower wheel plus at the heater duct as well. Good luck

Looks as if the dryer motor came unplugged. Repair man said he'd have to order a new one for $465 (parts/labor)!!!! I'd rather buy a new dryer at that point. He said not to use the dryer cycle until the part was replaced. Well..., it's working just fine and the code never returned. Interesting.

I was having the same issues with the DHE error. I have a dog and figured it was hair in the pumps, etc. I first flipped the machine over, took out the pumps, disassembled them and cleaned them out. There was some muck in there, but not enough to concern me. The 'propellers' actually pop out of a waterproof housing to be able to be rinsed - carefully. I reassembled the pumps.

Then I took the top off, opened up the dryer duct on the top, wiped off the dime sized sensor on the left hand side of the shoot, made sure all of the wires were secure (seemed like they were, but with the previous posts, just made sure). Reassembled, and have not had any problems since. It is working great!!

    Also, here is a service manual for the LG combo. I have the MW3677HW, but it seems I could not find that one, but it seems very similar as a newer model that replaced this one. This will help with the disassembly and other service issues.

The machine needs water on a dry cycle to cool the drum.

When you start your machine is the water just go stop go stop,
Just wait for the machine to display an error code on the wash progress lights and beeps constantly.
It could be the Rotor Position Sensor, out of balance switch or lid magnetic reed switch.
Your error code will determine this.
Is your machine beeping & showing a weird pattern of lights on the wash cycle, It is displaying an error code,
To read this error code you start at the red spin light & work to the left only add up the lights that are on. Red spin light = 1 2nd rinse light =2 1st rinse light =4 last wash light=8 4th wash light=16 3rd wash light=32 2nd wash light=64 1st wash light=128

Alarm which we do not have before. normal cycle. also on a rinse cycle. ocasionally loud banging noise.


You didn't mention if the machine was giving any error codes. Do the following steps to get any stored error codes and post them back to me.
Select the following on the operator console - DRAIN SPIN, NO SPIN, and then press any button under OPTIONS 4 times (it must be the same button). "C00" will show on the console display as the washer begins diagnostics mode.

LG error code is 0E...what would be the problem


Washing machine has an LE error code --> Is this a new installation?
In new installations, this error can sometimes present because of a miscommunication between the control panel and the wash motor. In this instance, the washer simply needs to be reset.
Step 1: Unplug the washing machine.
Step 2: While the washer remains unplugged, press and hold the [Start/Pause] button on the front panel for 5 seconds.
Step 3: Plug the unit back in, and run a rinse and spin cycle to test if the LE code is cleared.
Has a large load size been used with a gentle wash setting?
Gentle wash cycles such as Perm Press, Delicates, Hand Wash, and Wool/Silk should only be used for smaller loads. Because the cycles are more gentle while tumbling and spinning, too many items in the drum can register as an issue with the motor. In this instance reset the unit and run a test rinse and spin cycle.

Has the washer been overloaded?
Single bulky items or large loads can add extra weight to the drum and place stress on the motor. Remove some of the clothing and restart. If the issue is still present after a few items have been removed, unplug the washer for 30 minutes to allow the motor to cool and then restart the cycle.
wmoverloaded.jpg NOTE: Make sure the drum is not overloaded
Are there soap suds visible in the drum?
Over-sudsing is the main cause of LE error codes. Using non-HE (high efficiency) detergents or too much detergent will cause stress on the motor. In addition, detergent residue can also cause leaking and odor. Follow these steps to resolved an LE error code caused by over-sudsing.
Step 1: Unplug the washer and allow the unit to sit for 30 minutes to give the suds time to dissolve.
Step 2: Plug the washer back in and press [Power] to turn on the washer.
Step 3: Do not choose a washing cycle. Press the [Spin Speed] key until "No Spin" is selected.
Step 4: Press [Start/Pause] to begin a drain only cycle.
Step 5: After the drain only cycle has completed, remove the clothing items from the machine. Turn the power back on and select [Rinse and Spin] and then press [Start/Pause]. This will remove excess soap suds and light residue from the drum. Repeat this step until no visible suds are in the drum of the washer.

Won't spin


Close the door firmly and make sure the machine is turned on. Press and hold the Chime and Extra Rinse keys until the control beeps to enter Service Mode. All indicator lights will turn off except the "Door Lock' indicator signifying the door is locked.

Press the Rinse & Spin key then rotate the cycle selector knob in either direction to display the most recent error codes if there's any. Press and hold the cycle selector to display the number of cycles since the error occurred. List down at least five most recent codes and post it here for us to determine what the problem could be. Press and hold the Delay and Chime keys for three seconds to clear the list. Press the Rinse & Spin key again to exit diagnostic codes list.

Press the Spin Only key while in the Service Mode to begin the Board Input Test. Set the rotary cycle selector to Super Wash then press it to display the position of the door switch. "OP" will be displayed if the door switch is open or "CL" if it is close. Replace the door lock/switch assembly (part #34001265) when "OP" is displayed even the door is close. Press the Spin Only key again to exit the Board Input Test.

Press the Spin Speed key while in the Service Mode to begin the Board Output Test. If water is present in the tub, set the rotary cycle selector to Quick Wash then press it to turn on the drain pump and drain the water. Press the rotary cycle selector again when the water is fully drained to turn off the drain pump.

Press the Delay button to turn on the motor and the Delay indicator light. The machine should tumble clockwise then counterclockwise with 5 second durations each and 2 second intervals. Press the Spin Speed key again to exit the Board Output Test.

Press Off or press and hold Chime and Extra Rinse keys for three seconds to exit Service Mode. Unplugging the washer will also exit Service Mode.

Perform the tests above and let us know the results for us to determine the cause of the problem or the necessary action to undertake and give you the specific and detailed instructions on how to fix it.

How to resolve "PF" power failure on an lg WM3431HW Hello, I have an LG WM3431HW which is a combo washer/dryer. It is around 4-5 years old. It was working fine, then recently after completing the washing cycle and after a few minutes after the start of the dryer cycle. The dryer cycle shuts off without error (power to unit still on). We opened up the top and cleaned out all the lint caked on within the dryer duct and made sure lint trap off drain pump in front was cleaned. We started again and received a DHE error. We confirmed the dryer element was heating up fine. We also tested continuity to through the dryer thermostats and it had continuity. Also confirmed appropriate voltage over dryer element. We then took dryer duct fan off, turned it upside down and re-connected to make sure it was turning properly. It seemed to start and stop and it was also very hot so we thought there was a problem with the fan so we replaced the fan, and to be safe, also replaced the thermostat. Once that was done, a few seconds after the unit goes into the dry cycle, the cycle stops and shows a "PF" power failure error. We checked all connections we can find but everything looks connected correctly. We eye-balled the power board to see if there was any burn spots or anything else noticeable but nothing. We also eyeballed the power filter for the same but nothing looked out of the ordinary. The heating element was hot and confirmed the dryer fan duct was revolving, albeit for a short time. It seems that there is something tested after the heating element is started and the fan revolving, that is not working and which is telling the unit to shut off or "power failure". We had also unhooked the dryer thermistor to see if anything looked unusual but looked fine and re-connected. What else can I check and what part is likely to be at fault ? Since the wash cycle runs fine, I am hoping the power board is fine. Thanks
