Hello everybody. I was wondering what the lg washers look like on the inside. What kind of suspension system does this washer use? What do the drive motor, pump assembly, steam generator and various parts look like? How do they operate? What do all the models look like on the inside particularly the wm2487? Do they use bearing oil or no. I understand that they were made in Korea. I would like to get a better understanding of how these washers are built so I don't always feel too uneasy of what seems to be flimsy quality. Thanks.

LG...

I have seen two types of motors used in LGs: belt drive with a brushed"universal"motor and some models with a direct drive electronic driven motor-direct drive is much quieter and allows special wash motions on certain machines.The direct drive motor consists of a drum about 10"diameter with magnets around the inside of the outer rim,a stator rimmed with electromagnetic coils fits inside the drum and is mounted to the outer tub.There is an old thread on here where a badly corroded spider is replaced on a direct drive LG-thread title is something like "meet horsey"Corrosion of the spider-usually of cast aluminum-is a common problem with front load washers,often a "death failure"with these machines when the spider corrodes and breaks-a variety of factors determines the severity of corrosion from minimal to severe.The pump in an LG is the usual wet rotor permanent magnet "magnetic" type.LG is made in Korea,started selling goods in the US~1982,selling mini fridges and small black&white TVs under the "goldstar"brand :) No bearing oil-just greased ball bearings.

model 2487

What does the 2487 look like on the inside? How big is the drive motor of this machine? I was under the impression that this is a direct drive. Where are the ball bearings? What type of grease do they use? What about the suspension system?

Seriously Jerome, do some internet research. All these parts you want to see are readily available on the internet and Youtube.
Look up repair videos. Search for LG and Samsung patents in Google Patent search.
Look up repair parts via a model number search on RepairClinic.
I've been feeding my curiosity this way for years.
Why do you expect us here to spoon feed you EVERYTHING?

Go onto the internet and look up "using a washer motor as a power generator powered by wind or falling water"That may give you an idea what the DD washer motors are like.And these power ideas actually can work.So--some of the "scrap" value of DD washers is in their motors "recycled" for small power generators.Hint-go to a place selling the DD washers-LG or Samsung--Give the drum a good spin-the washer dial lights will come on breifly and it will play a tune--The store salesmen love it when you do this-gets their attention!!

Some advice...

Go to your local hardware store and purchase a set of tools. You can tear apart a machine completely using a decent screwdriver set with torx bits, a socket wrench set and maybe an anti-tamper screwdriver set. (At least, I did with my old FF. I'm not sure what other tools one needs with modern machines, but that's a start!)

Then go onto Kijiji and find very low cost or free machines. Maybe a used appliance place might have something you can tear down for parts.

Then just go to town. That's how I learned. Don't worry about breaking anything. It's easier to tear the machine down than it is to put it back together, which you probably won't anyway. :-)

There are service manuals on the net that show how to tear the whole thing down and put it back together, step by step. You know you are doing things right when you can put it back together, not end up with any extra screws and it works. :-)

There are also really good youtube videos online that show how to do a trunion bearing replacement for Whirlpool and GE washers. They literally have to take the entire machine apart in order to get at it.

There are massive amounts of youtube videos out there that show all of the basic concepts you need to know. Although, nothing beats getting ones hands dirty!

Slowdown folks, we are dealing with a young man here and we need to take our time to show him the rope!
This maybe his first major message board participation that he has joined and it takes time to learn and understand how it works...
Some message boards are complex or inefficient with data that makes even me go crazy, take a moment and remember how we all got started!
I've seen a recent Hozzer (THS/GardenWeb) thread who was former member of this site who is still bitter from what happened in the past wrote a nasty gram about AW.org..

spinning the drum

Does the drive motor inside the machine create voltage when I spin the drum, which may cause the machine to turn on, or does it stay off like other brands like whirlpool?

spinning the drum on a late DD GE...

I spun the drum briskly on my 2012 Chinese made 24"direct drive GE and nothing happened-have heard many times LG DD s will light some of the indicators if spun.

been there, done that

I have done it before, but wasn't sure if it would turn the machine on.

What happens on my Fisher & Paykel direct drive topload washer is this:

1) If there's a load running and a power failure occurs during spin, the motor will generate enough power to keep the electronics on and the lid lock engaged for safety purposes until it coasts to a stop. Then the machine turns off and remains off until power returns and the cycle resumes where it stopped.

2) If there's a load running and a power failure occurs during any operation other than spin, the machine simply stops and remains off until power returns and the cycle resumes where it stopped.

3) Rotating the drum by hand when the machine is off does not cause the controls to turn on, but if rotated fast enough the motor may energize into a braking mode.

This was a few years ago when I did the drum spin thing in the LG and Samsungs-will have to try it again and see if the design has changed.Spinning the drum doesn't turn the machine on-the motor acts as a generator and breifly powers the electronics until it slows down and is no longer generating electricity..PM motors will become generators when turned.This can make them useful as generators as well as motors.

The LG s still lite up but go off as soon as the drum stops. I do, it at Home Depot to show the customers as the salesmen watch in amazement. If you go to Facebook, I have still photos of the disassembled 2277 Steam model. I had to replace the barings,tub seal,inner tub,outer casings and pump. I found it in a trash heap free. I sold it for $750.00

Yes,like the floor nozzle of a Kirby-a simple electric generator.The brushroll has a small magnet that goes past a coil of wire connected to a LED.When the brushroll spins at the right speed-the LED gets enough voltage to light.

There are some videos on Youtube

iheartmaytag's profile picture

Where they use a F&P top load drum and motor as a waterfall generator.

 

Electric motors are just generators in reverse.  It's a way of transmitting the mechanical energy converting it to electric energy and converting it back to mechanical energy.   (whew, I'm glad I was awake that day in Physical Science class).

circulation pumps and drive motor operation

I could've sworn that there are models with circulation. How does the motor know when to turn in the opposite direction? Example: cotton/normal operation. How does the machine know when to turn on the circulation pump?

iheartmaytag's profile picture

Through the machine's electronic controller.  They actually control everything, this is why they are needed because many of the operations the electronics monitor and control are far beyond the abilities of older mechanical timers.  If the mechanics were able to control everything they would be so large and complex that their cost would outweigh that of the machine.

The computer control board changes the electric current to the motor for which direction to turn according to the cycle program sequence.  The pump is a separate circuit on the control board.  The microprocessor turns that circuit on when the cycle sequence calls for circulation.  Simple.

short bursts

I have to wonder how the computer tells the machine to add water in short bursts. Why does it do this?

water level and suspension

What does the suspension system look like in the lg front loader? How full of water is the outer tub if I barely see any water? How does water saturate the clothes if I barely see water after filling and before circulation starts? I am talking about when tumbling.

Why have some of you guys got to be arseholes? This is a washing machine thread. You guys are supposed to be experts and enthusiasts. Believe it or not you can't find absolutely everything about everything on the internet. There are a handful of videos which show bits and pieces. Maybe the guy was thinking some of you had pictures, being technicians of machines and so on.

These forums are so hostile at times.

Just look at some of the other recent posts on this forum lately...
This is one of the most helpful and friendly forums I have ever seen. People go out of their way to post cycle guides and other detailed info, but it doesn't seem to matter. If there is hostility, there is a good reason.

The cycle programming embedded into the logic chips on the board controls every aspect of the machine's operation ... just like Windows or whatever is the operating system on your computer or phone controls its operation. A water level sensor, same as on any other washer, monitors the water level in the tub.  The control board adds water until the sensor registers the correct level.  Filling is done in short bursts to give the tumbling load time to absorb water and get saturated and minimize the need to add more water later.  If filling was done very quickly, the water level in the tub may register as full on the sensor before the load is fully saturated.

I don't have an LG to show its construction but perhaps these pictures of a Whirlpool Duet will help clarify for you.  I imagine most frontloaders have a similar suspension arrangement.  The tub hangs on large springs at the top and is supported and cushioned by hydraulic shocks beneath.  You can see the two shocks beneath toward the front, there are two more at the back.

These next pictures show with the front half of the tub removed how much space is between the outer tub and inner drum on the Duet.  There's a deeper sump area at the bottom which of course has to completely fill with water until there's enough to reach into the drum.  The water heating element fits into the metal clip at back of the sump.

Another view of the drum and tub.  Water saturates the clothes by way of the fill flow spraying directly onto them if the machine's design does that, and by the clothes tumbling through the water as rises up at bottom of the drum.

I wnnt to say thank you,  very nice visuals.  I actually own one of those machines, and since I have never had it apart; did not actually know what the innards looked like.  .

 

Very nice--Thank You

Never seen the inside of the older Duets. It does seem that newer Duets are being built better actually. The tub hangs off of a strong metal bracket which goes across the top unlike the tub hanging off the side panel on older ones.

balance ring

johnb300m's profile picture
I couldn't help but notice the absence of a balance ring on that Duet exploded parts photo.
I know it's customary to see a balance ring filled with bearings or water on most front load and top load machines.
Does WP handle the balancing of the tub differently?
Curious....

Duets with different innards and outards!

DADoEs, What model Duet are those pictures from? I have a 9150 model and it has the straight baffles in the drum. I would think the ones in your pics would do a better job of moving the clothes around the drum. With your model number I can see if they interchange with mine and maybe "upgrade" our washer.

As far as suspension goes, mine only came with 3 shocks from the factory which seemed to be correct as my sister in law had the same model and it only had 3 as well. I added a 4th shock to both of them and it did help.I also replaced the original springs with a newer part number and they seemed to lift the tub up a little bit.
My drum hangs from the sides on those two springs like your picture shows and I think it could use something more which would keep the drum more level as it drops down a lot in the front when loaded.

And a balancing ring would have been a smart way to go as these machines will not spin if they cannot balance properly.

And I have had problems with the water valves and their ridiculous connections. I lost the bleach dispensing capability a few months back and wound up taking out the factory connector on the valve and replaced it with small stake on terminals and have not had any problems since.

GHW9400PW4.  2004 model year, mid-2006 manufacture date per serial.  It doesn't have any physical off-balance switches so sensing is done via software and monitoring of rotational inertia.

It was bought used ... or more accurately the matching dryer was bought used and the washer (which had been condemned for bad bearings) was tossed-in for free upon request.  It's not mine.  I refurbed the pair for a friend for use at one of his rental properties that needed a stacked set.  There's a thread back in Nov 2012 covering that process.  I used it for several weeks after finishing the job and found it to be an impressive piece of machinery.  The renters haven't had any problems that I've heard, and I would have / will hear about it if they do.

Thanks for the info.

I don't think ours is that old but I bet they are very much related. My exact model is WFW9150WWOO Ser. HLY4590937 WITH A 4.0 cu.ft drum.
I will check and see how close they are and what might be interchangeable. Always looking to improve the cleaning ability of this machine.
