Title: LG WM3370HWA Front Load Washer - Loud Thumping, unbalanced drum during spin
Post by: pupham on June 12, 2017, 11:36:30 AM
Hey All,

I've been looking around online for a few days now, and I still am unable to pinpoint what exactly our issue is, so I'm reaching out here before I bring in a technician.

Our 2 year old LG front load washer (LG WM3370HWA) has been making a distinctive banging/thumping sound during the spin cycle. It seems to be because the drum will be out of balance, and it will start shaking itself around rather aggressively. It doesnt happen with every load, and it does not do it when the washer is run without a load. I removed the top panel to have a look, and the inner drum seems to be leaning back slightly, and the rubber gasket seems to be a little misshapen like the drum is not in its normal position. Both support springs look fine, and the shock absorbers underneath seem to look alright as well. Are there additional supports that I'm not seeing that could cause this? Is it just a worn out shock absorber?

We just ran a cycle, and the shaking was so bad that the inner metal drum started to scratch the inside of the glass door.

Anyone have any insight to this issue?

 If the tub support is not broken, it may be a bad rear shock. Maybe the rear shock is broken or disconnected.

Thank you Scrapiron! I'm going to replace that shock and see if that does it, if not I guess I'll be using a lifeline.

Thanks!

Pupham open the door and try and lift up on the Stainless Steel Tub - does it give/wobble/move significantly? Do you see wear marks on the rubber door boot? Or look inside the bottom filter when removed do you see any shavings inside the filter when you pull it out. IF YES to any of these questions you more than likely have a broken/cracked Tub Support Bracket (Spider Bracket) see picture attached. Let us know what you find.

Well, I figured it out. After taking off the front panel it was obvious (See pictures). The bottom counter weight on the front of the drum had completely fallen off. Nothing looked broken, and I couldn't find any missing hardware (washers would be what was missing), but there was nothing. It just looks like a bad design, not having anything firmly securing that bottom weight onto the drum (the top weight had washers). I went out and purchased some appropriate washers, and reinstalled the weight, securing it with the washers and bolts. The washer is now back to working like a charm. Really happy I held off on calling it in!

Hope this can help someone who runs into a similar issue!

Just wondering how the heck the 4 bolts would come off that counterweight they are pretty heavy duty. If they came off that easy you might want to apply some loctite to the NEW BOLTS if you haven't done so. Thank you for responding back and letting us know.

That's the thing, those bolts were still completely in place, hadn't moved. It looked like the counter weight was just sitting there. That's why it makes me wonder if washers were supposed to be there.

Joined this forum just so i could respond to this thread and say thanks... LG WM3170CW front loader that is just a little over 2 years old... was banging so hard during spin cycle that the drum was hitting the glass and twisting the door seal. It sounded like a machine gun. Especially bad during intital spin up. Some cycles were fine, others were awful. 

Took the machine apart hoping something obvious would jump out at me, and sure enough, removal of the front panel revealed the front bottom counter weight completely disengaged from the drum sitting on the floor. It is not held in with washers but with self tapping lag bolts that have a tapered head. As you drive them in, they spread apart the wings of the male pegs the weight rests on and friction hold the weight. Awful design.

For now, I removed the bolts, re-attached the weight, installed the 10mm bolts and made sure they were very tight. If the thing falls off again I will install with a regular bolt and washer.

I believe I contributed to this failure by frequently using high speed spin while the machine only had a single bulky item in it (not using another article to balance it out).

Thanks good info to all of the above! Same thing here on this machine, it has worked great for the last few years and then the bottom counter weight fell off. Really curious why the top weight has a set of washers on the bolts and not the bottom??? Just paid yesterday to have it repaired, the machine sounded fine. Today the washer was thumping and jumping again! About to take it apart and set some washers on the bolts. Crap design, or laziness/cheapness at the factory.

I joined just for this thread also.
Have a slightly more than 2 year old 3370HWA washer, and I think suspect have the same problem. During a load the other day heard a really loud thud and then the tub was unbalanced. It was odd because everything seemed to be working fine. Did two more loads but it could never really get up to spin cycle speed. I'm sure the issue is the broken counterweight.

My question ... Our W/D are in stacked configuration, and in a tight space. It is  :tickedoff: that you have to take off the rear and top panel screws in order to access the front panel, at least according to what I've researched on YouTube. Does anyone know if I can pop the front panel while the dryer is still on top of the washer? Can I slide the top panel back with the dryer still on top? I hope so, otherwise this DIY job is going to turn into a ridiculous labor service call.

Crap, this is going to be really annoying. (searching: "weight of LG DELX3370" ...)

So just an update for the board ... you actually only need to pop the top lid back by about 2 inches to get a low profile ratchet screwdriver to get access to that single, lonely, only screw behind the control panel. I did this with the dryer still stacked and slid it back only 2 inches and was able to get to the screw. That was a relief!

The thing I had a hard time with was getting the boot retaining spring back on ... no one seems to sell those wide range spring clip tools ... I'll have to make one. It's a simple looking tool, but you need jaw spread of 4 inches or so in between the eyelets of the coil spring that adds tension to the wire hoop that keeps the boot in place.

Anyway, much like this forum predicted, my counterbalance weight also fell off. Unfortunately, one of the male posts had shorn off! The far left one. The posts are split into four slices so to say, so for that post, you can't even put the screw back because of the sheared off male mount. This design ... I dunno, maybe there is a high-cycle reason it was designed like that, but it escapes me. I used some epoxy and bolted the other three back in with washers.

While I did add the washers, they don't really do much good. I suppose they'll do a little bit of improvement and prevent the weight from walking off the mounts again, but as was evidenced by my counterbalance, when part of the expanding tabs break off, the whole bolt-washer-tab would go with it. Now I think the forces will be transferred to the mounts if the weight can't move and eventually those mounts will fracture, just like the other one did.

Also, that part is like an entire washer drum surround ... looks like a major PITA to replace. Such horrible design here. I think it might be worth a class action for everyone suffering these design defects. Perhaps it is a loading design, a cyclic design, but I could also see that there is a lot of expansion/shrinkage from temperature changes and perhaps that polymer they selected doesn't do well and that leads to failure. Whatever, this is a horrible design, but it's pretty easy to tear into and get access if you follow the YouTube directions. 

Good luck everyone.

I have  just read the info about the counrerweight coming off and it must be a crappy design. If it was me I would try to put it back in place using thru bolts with Loctite but it may not be possible. All of the front load machines  such as Maytag or Whirlpool I have worked on have never had that problem.

Thank you, thank you, thank you! After doing a heavy load of laundry with extreme “clunking” on the spin cycles, my rubber seal was slightly smashed against the front, I knew something was off.  I started researching and found this thread and another site where one of the two springs holding the tub housing in place had either come off or sheared off. I figured it had to be one of these two things.

I got the hubby to open things up and we saw the springs were fine, right from the top.  He then pointed a flashlight to the bottom and could see the bottom counterweight was on the floor. 

We were amazed, as everyone else was, that the thing didn't seem to be fastened at all. The top weight had washers, why didn't the bottom??? Granted, it seemed like the split housing that the bolts screw into looked like the bolts needed to be tightened to spread the housing out to hold the weight in place with pressure, but we all have occasional heavy, unbalanced loads, and I didn't see this holding. My husband figured that they WANT the darn thing to fall off for an easy house call.

Long story short, he put washers on to hold it into place. We are just having a bit of an issue getting that spring thing that fastens the rubber gasket to the front of the machine back in, as we don't have the proper tool. Sooner or later we will get it and be back in business. Thanks everyone!

I have the same problem; the bottom counterweight fell off (there are no washers) and the left-most mounting peg is now shorn off at the base. I agree this design is so bad that it may be deliberate.

I plan to reapply the bolts with some form of glue (maybe contact cement or locktite) as well as washers. For the broken mounting peg, I'm going to try replacing the bolt with a longer version so that I can anchor it deeper into the tub surround.

QUESTION:  does anybody know how thick the tub is? Am I likely to puncture right through to the cavity that is filled with water? If I do, will locktite or another glue keep it water-sealed so long as the bolt stays in place? Any help answering these questions would make me feel a lot better.

MACGYVER SOLUTION FOR REMOVING SPRING CLAMP:
To get the spring clamp off, I used a small wrench (double-ended open jaw) and a loop of wire. On one of the eye-holes, attach a short loop of wire sized appropriately (read on to understand). Put one of the wrench prongs into the other eye-hole on the opposite end of the spring, holding the wrench parallel to the spring. Then stretch the spring until your loop of wire reaches the unattached end of your wrench. To do this, I tied a loop of string/rope to the smaller loop of wire so that I could get a grip on it and stretch the stubborn spring. Then you can remove the whole clamp from the washer boot and set it aside; it should hold together until you're ready to put it back on :)

Will post a picture later from home!

Did the washer trick work with the lower weight?  Mine fell off and it did it a second time, so I'm thinking of putting washers on it.

What a crappy design. Hope you get this one back together but I would take it to the junk pile and get a more reliable unit such as a Speed Queen top load.

Yep, the washers worked like a charm - the machine is still operating well and it's been several months. One of the mounting pegs had broken off on the initial breakdown, but the washers on the remaining 3 mounting pegs are holding it on just fine. Glad I didn't call a repair guy or replace the unit with a new one! Saved some money for sure :)

JarfGartz, great to hear.  I ended up putting washers in as well. 20 cents a washer, for an 80 cent fix.  I was not looking forward to replacing the hub cover. I was able to wash a few loads of blankets and it seemed to be ok.  Cross my fingers!

Just to keep this thread alive as the LG nightmare does not seem to be going away.  I had the same experience with my LG WM3570HWA.  There was enough information on this thread to give me the courage to take a look under the hood.  What I found was just like everyone else, my bottom counter weight on the washer floor.  I did not replace with washers but just made the bolts very tight and added loctite.  I have had this washer for 3 years brand new and it has always made some type of noise during the spin cycle.  Recently the sound has become much worse, our machine is on our second floor and I swore it was coming through the ceiling.  It also grew legs and walked around our laundry room.  Long story long, this reattachment of the weight fixed everything (makes me think the weight was never properly on the machine from the store), prevented a service call or new purchase and the machine has never ran so quietly!  Thanks to everyone that posted this similar problem and the the solution!

The weight just fell off of mine last night during high spin. Sounded like a truck ran into the side of the house. Popped the gasket off, lo and behold, there was the weight sitting on the bottom. Thanks all for posting pics and info. Helped a great deal!

I've been a service tech for 40 years and have had numerous LG front-load washers with unattached lower counter-weight.  More often the solution was to replace the front outer tub if half or all of the split bosses have broken off.  If the bosses are mostly intact, you can remove the front outer tub, drill 4 holes through the plastic, and use a stainless steel nut and bolt with a thin rubber gasket under the bolt head.  Bolt head must be low profile.
