Hello,

Long time reader of the forum and have found invaluable information. I have been using my LG WM3900 for a few years now and I have been very happy with the machine except for pilling of clothes. I use Perm Press on Warm or Hot for just about all of my clothes except for towels, bedding and delicate clothing. My Perm Press cycles are generally 30-35 minutes long with Turbo Wash enabled. Occasionally I will use Normal or Sanitary to gain access to Extra Hot. I only use powder.

I have noticed pilling on our clothes. This is likely due to the washer as I hang dry most of our clothes and then finish with a 5 minute air fluff in the dryer.

Is Perm Press the recommended setting to use or should I be using a different setting? Is it possible my loads are too small? Is the water hack/adjustment worth it?

I have a WM4200, I thnk Towels cycle uses more water. And it gives 3 automatic rinses as default.

I find Towels setting to be too long with all of the extra rinses for regular clothes. I suspect longer wash cycles would result in more pilling? Or is it possible Perm Press doesn’t use enough water so there is too much friction (against the drum and other clothes) causing pilling?

I should add I wash all clothing inside out, and closed zippers/buttons. Typically I wash zippered clothing separately.

I'll give you another hin. Add 4-6 cups of water to the tub before you add garments for the load. that will "trick" the machine into thinking it's a huge load and adds additional water per fill. I do this when I use Normal and Heavy Duty in particular. Also Whites. Adding the water doubles ewach rinse cycle and can increase final spin time. As example, Whites rinse cycles is 2 minutes after it finishes adding water, will end up being 4 minutes. On Normal, each 1 minute rinse is doubled to 2 minutes after it finishes filling.

That's a good hack, but this is precisely the sort of thing that turns me off of modern machines and a major reason I'm always hesitant about them. One should not have to hack/trick the washer, it should just do what it's supposed to do from jump.

OP

The Permanent Press cycle is actually a good one. If you do not dry clothes, from what I understand, there is a greater chance that the 'pills' are not fully removed after washing. If you even dry the clothes once, I would expect a noticable difference. However, a detergent with Cellulase will help remove the pills and prevent them from forming. Keep us updated.

Water hack

For the OP is the water hack worth it? For myself, I am happy with it. Clothes wash & rinse to a satisfactory level and the machine is still very economical on water usage. I found the Permanent Press cycle to be pretty underwhelming on my LG (model 8900 series) so I recommend the Bedding cycle as it uses more water and does 2 default rinses. Towels will do 3 as previously stated and also has a higher water level. Not an expert, but I suspect fabric pilling may be coming from the friction of clothes tumbling over and over again without a deeper pool of water to land in.

@ appnut.. isn't your machine out of warranty? Just curious why you don't adjust it to use a little more water like a lot of others I've seen...

Post# 1191028 , Reply# 8   10/1/2023 at 09:04 (210 days old) by jbrady3324 (Evanston)        

I am going to try the water hack. Should I be concerned about settings like Towel using too much water after the hack?

Are there any powders formulated to remove pills?

I can't tell if you have a front- or top-loader LG. My top-loading LG also causes pills on synthetic and cotton knit shirts. I found that if I turn them inside-out before tossing them into the washer and dryer, the pilling is reduced significantly. They seem to get clean anyway.

Miele make Cotton Repair capsules that are supposed to be used on a long, warm cycle. Essential an cellulase enzyme soak. Don't know how effectively it would work in an American washer, unless you can get a wash for about an hour or two maintained around 100F. Being Miele, it's also $23 for three capsules.

Personally, I'm a big fan of these lint or fuzz shavers.

No, 1.5 quarts (6 cups) causes no concern at all. Towels cycle will be fine.

EuGene, it's a front loader.

I have a front loader. I just completed the water adjustment “hack”. Super easy to do. Very happy with the results in terms of increased water level. Have not tested washing clothes yet.

Decoydriveboy Water Hack

I adjusted the screw about 1.5-2 turns. The water level during the wash cycle is below the door gasket by a good 1-2 inches. However the rinse cycle is above the door gasket. Have you observed the same?

Well that's what great about LG front loaders is that they use MORE water to rinse than they do to wash...and I don't think a lot of people realize this because most people don't watch their machine do it's thing...I think they see the wash and quickly assume that's the max fill for every fill.

I've seen some videos of cycles of LG front loaders using A LOT of water in the rinse and that wasn't adjusted at all by the user... so if someone adjusts it they need to keep that in mind. Washes will be higher... but rinses will be even higher than that.

I wish I could remember the video I saw of the guy sitting in front of his washer. I think it was bedding. And it went into rinse and the water was getting really deep and he's like "Wow... enough water already".. so it was even using TOO much without being adjusted at all. I think it was one of the square door model LG's.

When I watched Eugene's video about adjusting the water level, he said to make sure you give a reference point so you know exactly where it was originally if you're not happy with it..

I think Eugene adjusted his LG water level because it didn't have turbo wash. I feel like I remember him mentioning that he didn't think you needed to adjust it at all with models that have turbo wash.

Turbowash + Water Level

@Mark I have definitely observed the increased water during rinse. I decided to turn the screw back a tad and now the water is right at/below the door during the rinse cycle. Occasionally slightly above. I have run about 3-4 wash cycles now on Perm Press and Towels. The clothes/towels lift and fall and everything is coming out noticeably cleaner in terms of smell, vibrancy, and softness so I think I have found the sweet spot although I may turn the screw back a tad more. Based on what I have observed so far, I do think LG machines with Turbowash benefit from the extra water.

I can’t make any conclusions regarding pilling just yet. I will be able to report back after a few washes of the same items.

I do have concerns about long term wear.

Long term wear: One of the giveaways is if you notice less or more lint on the dryer lint screen. When I got my duet FL back in 2005... I remember that's one of the first things that struck me...way less lint on the dryer lint screen. I really don't think that should be an issue. I've never noticed pilling but I always use the dryer.

I wonder what just 1/2 turn would do...

I'm really cautious after I tried this with my duet years ago before putting it back. It's sort of given me PTSD when it comes to adjusting them because here's what happened when I tried to do it. Hopefully this wasn't the case with yours

I turned the screw like a quarter turn...checked the level and I saw zero difference... another quarter...same... another... same...I was following the exact instructions online...after doing this a few times a change started to happen...the water wouldn't stop filling until it was 1/2 up the door... there was no in between.. It was all or nothing. So I moved it back and never messed with it again...I remember when I got it back I was praying things would go back and I hadn't screwed something up royally. I was so afraid I ruined my machine.

It sounds like these are totally different...Do you remember how this worked? Say, when you were adjusting it.. did you just turn the screw all the way around right out of the gate? Or just a little at a time? I wonder if moving it a little at a time makes a difference or do you have to at LEAST turn it one full rotation? For me personally, I would only want about a gallon more per fill. No more than that.

For JBrady

Hi there, definitely you’ll notice the rinse level to rise up to the window with the hack depending on the cycle. Normal does this, as it uses about 3x as much water for the rinse compared to the wash. Some of the specialty cycles will as well. I use Normal, Bedding, and Towels the most. The last two have a consistent water level regardless of wash or rinse. My hack was 1.5 turns which is more than enough. Even with the water level not reaching the lip of the drum, this is already plenty IMO as the drum is so large and deep and the clothes are fully saturated with more to spare.

Mark and Decoy

@Mark - I made half turn adjustments at a time. After each adjustment, I ran a test cycle (towels) to see how much additional water was in the drum. This isn’t full proof as the water level will be higher with clothes in the drum but gives you a good starting point. I then left the top off and ran some cycles with clothes in it and adjustment further from there. What I did not account for was more water in the Rinse cycles so I ended up turning the screw back a bit.

@decoy - Do you think the water level slightly above the door gasket is okay? I also noticed the water temperature dropping about 3-5 degrees Celsius since making the water level adjustment. Have you noticed the same thing? I may dial it back a bit more to see if that raises the water temperature

OK, so as you did half turns only... did you see a difference with each turn? Slight as it may have been?

anyway - while waiting for your answer (since I don't own an LG) I would venture to say water above the gasket is too much. If you're watching it wash (keep in mind different load sizes might behave differently with more water...if you're seeing lifting and dropping that's good. If you're seeing rolling as it tumbles... it's too much... I don't know about the temp. I would say turning the screw adding more water than what the machine is spec'd for... maybe it's more difficult to maintain or heat? I don't know. I just guessing. Hopefully someone will answer

Mark - Good question and the answer is No and Yes. I did half turns only and I ran empty test cycles set on Towels (to get an idea of max water) for a few minutes and then drained. I noticed a difference with each turn. It wasn’t a drastic difference but it was definitely noticeable. However, I would suggest running the test cycles with a few towels as that will be more accurate of what the water level will be in a real life situation. I found the water level to be higher when testing with clothes in the drum likely due to the weight sensor and displacement. So I suggest testing with clothes/towels in the drum to avoid overflow situations.

I’m still tinkering (top is still off). I dialed back the turn to about 1 full turn to get the rinse level slightly below the door gasket and to reduce the water level for smaller loads (so they don’t roll). I think 3/4-1 turn is right for me.

The only way you're really going to know if your clothes are coming out cleaner or not is to do it scientifically by washing identical articles with the identical amount of the same top quality detergent and the same identiccal stains at both the factory setting and your "upgraded" water levels. Otherwise it can be discounted as wishful thinking etc.

The other thing to think about is that HE washers along with HE detergents are designed to get the best cleaning performance at the factory set levels. The detergents alone are super concentrated and should work their best at their highest concentration amounts, adding more wash water is just going to dilute them and they may not perform as well in lifting soil in the same amount of wash time. So long as they lift the soils from the fabric at the factory set wash levels the increased water in the rinse should wash all the soil away, that's probably why the rinse level is higher than the actual washing level. Anyways, just my two cents.

I feel like I mostly agree with that...Wash levels definitely are better low... rinses not so much... which I why I like LG because rinses are higher... they may be higher in other machines I just haven't noticed...with LG it's a noticeable difference.

Anyway - about the factory tests/ set water levels.. I understand what you're saying but I sometimes feel like they have to "compromise" to achieve energy standards... so a little more water might be better...even though it's not scientific... That's totally a guess on my part though.

If I had a brand new LG with turbo wash right now... I do not think I personally would mess with it...but I do love knowing that if I ever needed to I could.

I think the 50 to 75% would be the MAX I would turn it if I did it.. People have done this for years with their LG's.. I've read comments of videos to adjust water levels and many say they did it YEARS ago and never regretted it.

I wish I could remember an article I was reading about the appliance manufacturers complaining about how the energy standards for water use is too stringent and at some point they are not going to work properly..something along those lines... I wish I could find it.

It's funny... I can watch laundromat videos and I'm still seeing (in 2023) water half way up the glass door.. I guess they are exempt.

This whole adding water business is interesting. If I tried that on my Duet, the opposite would happen: the washer has a flowmeter to detect the amount of water absorbed and thus calculates how much water (a certain percentage) is added on top for the rinses. Manually adding water before the sensing is done, results in poor rinsing.

There's also a digital pressure sensor but I've never messed with it in 12 years of ownership.

Even though many have done it (increased the water level) for years and manufacturers feel it's a compromise does not mean that doing so would increase the washers performance. It can also mean that they want to cater to the consumers misperception that the more water they can visually see during the wash cycle means it's going to wash better. Just like the detergent manufacturers themselves know that lotsa suds does not improve washing performance but consumers think so. This mispercention is probably from the pre detergent days when more washing soaps were used and has since carried on. Therefore they add sudsing agents to their detergents,, well at least with the powdered ones for regular top loaders. They've done it for decades

As for "many people" have increased the water level.. not likely when you consider the tens of thousands of washers sold each year.. probably not even 1 or 2 percent

The probable reason the temp drops is something many machines have been observed to do, especially on more usage restrained cycles.

The washer has a certain hot water budget.
If it needs to add more water, that water will just be cold water.



It's also interesting I haven't heard about flow meters used in US washers while being basically universally used on any midrange and up washer over here.


The reason Logixx's Duet is different there is the entirely different way of sensing load size.

LGs haven't cared about absorbency really ever since they started doing the load sensing via drum movement.
That's why you can trick the machine the opposite way in the EU to give you shorter cycles with still decent water levels by letting sensing run with an empty drum, pause the machine and add the clothing then.


I do think that - especially with the TurboWash machines - increasing the water level will just be counterproductive.

The extremely short main wash relies on high detergent concentration and intense agitation with no water cushion.
The rinses are higher level as stated before.

@JBrady

Yes, I have noticed that the wash temp probably drops with the hack, as I’ve observed mostly cold water fill even when the selection below Extra Hot is chosen.

When selecting Extra Hot it tacks on like an hour to the cycle. I noticed this recently when using Normal … now when I select anything but EH for the temp, the default wash time falls back to 25-40 minutes approximately. I was confused about this initially in some of my older posts! We live in South Florida, so our tap water is always lukewarm, and wash temperatures are not as vital to me as the water level.

I think that water above the drum lip is too much - but this is subjective. We have a lot of stinky clothes and dog beds so I insist on having plenty of water to help get rid of odors. IMO, the ultra-low water levels are great for stain removal given the detergent concentration, but they are ineffective for odor removal, and I’m super picky about that.

@decoy

Totally agree! The increased water level removes odors significantly better. I noticed this immediately with my first was post water level increase. I have also noticed less pilling likely due to less friction with the increased water level. I have not noticed any reduction in stain lifting.

Just to confirm, your rinse levels are below the door gasket?

If this hack causes cold water fills unless extra hot is selected, count me out..

I'm trying to understand how more water in the wash can cause the odor to go away vs the non-hack. Either way you've got soaking dripping wet laundry...the only difference is the detergent is now even more diluted. I would think if someone smells really bad a soak cycle would be in order.

Low water washes do not bother me....as long as the rinses use plenty of water...

I can see how that would be an issue with pet hair or something...but even that could be minimized with the deeper rinses.

@Jbrady

Rinse levels are right at the drum lip (post-hack).

However, depending on cycle and load size, sometimes the rinse water will rise up the glass door. Most I’ve ever observed is probably 3” high or so.

Normal cycle rinse will pass drum lip at times and so will Speed Wash, and same for some of the specialty cycles on the app which I rarely use. I believe it was the Juice Stains cycle where I saw the highest rinse level ever.

Bedding and Towels have a very consistent water level for both washes and rinses so I use those and Normal most often.
