20 Most Recent LG WM3987HW Front Load Washer / Dryer Questions & Answers


the main drama i have with these lg washer/dryers is the drying vent blocks up with lint which causes excess heat build up around the heater and it often results in a small hole melting through the front tub under the heater vent where it joins to the plastic tub, it also results in water leaking out the melted hole when it dries but not during the wash as the hole is at the top of the tub, parts are relatively cheap for what they are but its a massive job to replace the front tub.

the wm3987hw has an internal fuse located on the "power connection noise filter", It's a transformer or something which cleans up the wall-supplied voltage a bit before it touches the expensive electronics.
You might just be able to replace just the fuse, otherwise the whole unit is part#6201EC1006T, about $50.
take the top off the unit (two philips screws on the top back) you will find the power noise filter on the top inside right wall of the unit. it's not terribly involved to do this fix yourself. 20minute job tops.

I also have this unit with the same problems. After lamenting on making a poor purchase decision, I found somewhat of a solution. Basically, water is not being expelled during the dry cycle. When I addressed this issue, clothes were MUCH more dry than before. Made a quick video demonstrating the fix: http://www.youtube.com/watch?v=8EhzuzSk2Ok

Looks like there's a fee for it, but this may be what you're looking for.

Probably a loose or worn belt.

I've just uploaded a service manual.

relevant info pasted below: --

Regulate a specific spin speed that generates excessive vibration and noise as follows:
1) Put an unbalance part (rubber) inside of the drum.
(this is a special weight that service people use. It clips into the drum. If you don't have it, throw in about 4 to 6lbs of damp laundry.)

2) Start the QC test mode (Refer to section 7-2).
7-2 says turn the washer off, then press 'spin speed' and 'soil level' at the exact same time. Then, while holding both buttons, press power to start "QC test mode"

3) Press Delay Wash button, then ' tst ' is displayed on lcd
4) Press the Spin Speed button repeatedly to select Extra High.
5) Press the Quick Cycle button, the spin speed is displayed.
6) Press the Start/Pause button.
7) Press the Beeper button repeatedly to set spin speed (600, 800, 1000, 1200 rpm) and check if there is vibration
and noise.
8) If there is no vibration and noise, increase the spin speed by pressing Beeper button.
9) If there is vibration and noise, rotate the Cycle selector knob clockwise to reduce the Spin Speed (reduce by 50
and 100 rpm). In case of 600 rpm, it can not reduce the spin speed.
10) If vibration and noise are reduced, press the Quick Cycle button to store (2 beep sounds).
* If you want to return to factory default spin speed setting, repeat above steps except step 9)

Hi Rick,

I found your answer to another person's problem with the LG washer/dryer not turning on. We have the same problem. My husband found a piece of plastic near one set of the fuses that looks warped - like it got too hot. Is there any advice you can give? It's a piece next to the box by the main power cord with a metal coil.
