I've been using the LG WM4370HKA for a couple weeks now. I like it for the most part. I think the rinse is truly reminiscent of Maytag Neptunes with the drum turning and making the water flow through the outer tub to clear out the suds. But one thing does bug me a little, the turbowash sprayers located on the 4 and 8-o-clock position don't spray at full intensity like they do on the rinse cycle when the machine is in the main wash phase. They seem to start up, spray at a good intensity then reduce pressure and you can hear air passing through the re-circulation pump and don't spray nearly as hard at all and sometimes barely touch the clothes. Who else experiences this with their LG when they select turbowash on the normal cycle? I've seen videos of the WM3770 and WM3570 performing and they never seem to experience a pressure drop with the spray nozzles during the main wash on the normal cycle.

I think why your machine is doing the reduced pressure for the TurboWash jets during rinse is the fact that those jets can kick up some sudsing. I notice it with my LG 3570 washer with some loads like towels and jeans. I believe that your machine is running normally in this instance. With my machine the TurboWash option is defaulted to on Cotton/Normal, optional on other cycles. I use TurboWash with every cycle and load since I love the spray rinsing during the spins between deep rinsing and during the final spin. I am amazed at how well the washer rinses the clothes. I do use a softener in the final rinse to kill any suds that might survive.

The normal cycle uses the least amount of water per DOE requirements. The pressure is reduced because the water level is only high enough to saturate the clothes. How long are you watching the cycle because it should eventually add enough water for the Turbowash to work properly.

The apparent lack of spray force could also be due to, perhaps, too much detergent, or a too sudsy detergent. I've experienced that on two different makes of machine with recirculation pumps.

Another thought: Is the sump filter clear of any obstructions?

Was just thinking, but pretty certain that LG uses a simple single speed recirculation pump.

Only variable speed recirculation pump I know of is in Mieles current PowerWash 2.0 models.

The detergent does not suds up to a visible point at all (Tide HE Turbo Powder). This washer is still very new so I don't think the filter has anything inside of it. In the last 3-5 minutes of the main wash, it adds cold water to use as a cool down and then the nozzles appear to spray at full intensity until the first drain/spin cycle. The clothes do saturate on the normal cycle, I just thought that the force of the spray would be more consistent as that's how it was in models like the one I own.

It sounds like it's working normally. I assume the Turbowash works just fine in all the other cycles?

BTW, the water it adds in the last few minutes is to flush the bleach dispenser (the spray nozzle and bleach dispenser are connected to the same solenoid).

I think for the most part yes. I've only used Normal for the most part and bulky/large for comforters and turbowash appears to work fine on that.

I think maybe the loads i'm washing are too small for this thing LOL. When it saturates the load, it compacts it so much that its easily only filling 1/4 of the tub where as I've seen videos of this thing performing with probably more than what I put in..which would then explain it would logically use more water thus spraying at the full intensity. Deans video looks like with the load saturated it comes near to the 1/2 full point of the tub. I guess I'm still used to the Maytag Neptunes capacity which was at the previous rental I lived at, an entire hamper of laundry filled the tub up.

I would think that the water to load size ratio should be the same. Say you have a small load vs large load - obviously, it's not going to use the same amount of water, but the ratio should be the same - and thus, the jets should operate the same - this is my thinking at least. I don't know. I'm probably wrong though, LOL. In that video I posted, it doesn't look like a particularly large load to me either... I will say that I have seen some LG turbo wash videos where the jets do exactly what you're describing during the wash, but not the rinse. Almost like the wash water level isn't deep enough for it to recirculate through the full tumble before it shuts off...

mark_wpduet's profile picture
this looks like a larger load, on the normal cycle with turbo wash, but with cold wash option....and the jets don't spray the full tumbles. The die down before the full tumble is over. It's like WHY? It's the same cycle? If anything, cold wash I would think would use MORE water, causing the jets the be stronger than just regular normal. I dunno.

Cold Wash probably uses less water for "concentrated cleaning". Frigilux described something similar for his Maytag's cold-water cycle. The rinses always seem to use more water than the main wash.

Having looked at both the videos, I agree that the rinses must be using more water than the wash portion.

I suppose you could try slowly pouring additional water through the powder drawer, to see if it makes any difference - maybe a couple of pints.

I did try that with a very small load before on this washer and the nozzles did appear to work without dying down. LorainFurniture's video of his WM3770 has to be the closest model to my WM4370 in terms of capacity and revision. His unit appeared to not only have a longer spin cycle but also the jets appear to be running at full force for the entire main wash. Granted it is a larger load so it would explain more.

My Kenmore Elite front loader does the same thing. I use the accelawash all the time. This is normal.

I know this thread is a little old, but hoping to necro it because I recently purchased a WM3770 and see the exact same thing described here, so I am a little curious.

On the "Normal" setting the recirculating pumps (I hate the term "turbo wash," even though I love the feature) more sputter than spray, regardless of temperature setting. I quickly concluded this was due to low pressure because the water level was so darn low. Adding some additional water (my utility sink is right to the left of the washer, so a 2' hose reaches easily into the detergent dispenser) quickly cures this and the jets spray at full temp.

The pressure and jets are at full force during the rinse cycles, so clearly the washer uses way more water rinsing than washing. They are also at full force during most other wash cycles, including Bulky, Sanitary, etc.

So is it just that Normal uses an extraordinarily-low amount of water during wash? It would seem so, and even though rinses seem outstanding I wonder if it saturates the clothes enough to clean properly? Has anyone used this setting on these washers long enough to verify they clean well?

Normal is the only setting other than Sanitary that allows the Very Hot (onboard heater) setting to be engaged, so in the end it does matter (unless I just use Sanitary for everything I want to be really hot). Not sure I want to be manually adding water all the time either.

Curious what other's experiences with LG washers with the Turbo wash feature are.

the normal cycle is the ONLY cycle that engages the heater other than Sanitary? That surprises me since normal is probably the most energy efficient cycle that I often avoid. I thought they had other cycles that used the heater like cotton, towels, etc.

Mark, only Normal and Sanitary "use" the extra hot temp option.  I venture to guess the ex. hot temp on Normal isn't as hot.  the Bright Whites.  Heavy Duty cycles also engages the heater with its hot water temp and max soil level.  These cycles also offer steam option which might increase the hot water temp.  There's also their Allergiene cycle which I venture is a very hot temp wash, but not as high as Sanitary.  But engaging the steam option on these cycles will help assure the heater being used for sure.  


One of the many reasons why I prefer Whirlpool and Maytag because of the additional flexibility with hotter tempeartures across just about all cycles combining with Extra Hot and steam.   

Post# 1030235 , Reply# 20   4/18/2019 at 20:44 by washerdude (Canada )        

Mine also only lets you pick Extra Hot on the Normal cycle and Sanitary. Really strange. On the Normal cycle, the jets don't activate at all when Extra Hot is selected, on Sanitary however, the jets spray the hot water onto the load and let it soak into the fabrics which is very effective IMO.

In terms of Turbo Wash performance...I think its a nice feature...just not on the Normal cycle. With Turbo Wash enabled on the Normal cycle, its really painful to watch. I just can't see how this can clean clothes properly at all and my clothes don't seem to be getting that clean with these selections. The spray is weak, the water temp is too cool (Hot: 34C-37C despite the fact my water heater is set to 120F/49C). The final spin bottlenecks the dryers performance marginally, only 4 minutes and the second it hits 1200RPM it cuts off and ramps down.

As a solution to this I just use the Bright Whites cycle with Turbo Wash. It uses warmer water (40C-45C), cleans FAR better, spins better (1201 RPM when High is selected and holds that speed for 5-7 minutes), the jets actually spray water - you name it.

The Heavy Duty cycle also faces similar issues in Turbo Wash performance but not as bad as the Normal cycle. The jets will spray the load, then stop, then turn back on while the drum is turning - and eventually will reduce to a sputter but then the drum stops spinning, goes the opposite direction and this process repeats for the rest of the wash cycle. The rinse is...interesting to say the least. It doesn't do a typical deep rinse nor does it do a proper lengthy spray rinse, in fact it only does that once during the final spin for about 5 seconds. During the rinse, it fills with a tiny bit of water, sprays the load and when the jets begin to reduce in pressure, it adds more water and this process repeats until the machine decides it wants to drain, but it never does a deep rinse on Heavy Duty. The water temp here is also fairly cool just like the Normal cycle.

In comparison to my Whirlpool Duet WFW72HEDW which was left behind at my old house...I felt as if that was a far more superior machine than this LG. I think in terms of cleaning, the Whirlpool Duet just crushed the LG. It rinsed better, spun better, balanced better, washed better - you name it. The part where this LG excels however, is its ability to wash comforters which it does better than my WP Duet did. Overall the LG is a GOOD machine once you work out the kinks here and there, but I do think LG should tweak it more.

Hope this helps! :)

We have the 8100 (whatever letters there are, it is the 5.2 cu ft FL) and I've noticed the same thing. Normal wash cycle the spray doesn't last. I have been using a second rinse with all the cycles. The machine does a very good job at getting items clean, but when I've seen it do the rinse cycle, the power wash jets basically just spray soapy water back on the clothes at the start of the cycle. I'm surprised they didn't include some sort of a purge to prevent that. It is more frustrating than anything. I will take the advantage of a full load wash, with one rinse, at 26 minutes (32 with a second rinse, 36 with two) over the oddity of the turbo wash jets.

I do think that when you select the steam function Extra Hot is part of the cycle. You lose the option of water temperature and soil level. The whites cycle has been amazing, I've yet to have a bad wash in it. I don't care that it runs long, it works really really well.

Before self-cleaning filters, that was common for machines with recirculating filter systems--saw it on Kenmore, Whirlpool, GE, and the Filter Stream spraying for both thee LK & WP combos.


As for your comment that you appear to lose water temperature and soil level options when steam is added, my Whirlpool duet doesn't suffer from those "problems" when I add steam.  If I need steam, I can still select wash water temps for warm, hot, and sanitize/Extra Hot as well as light, normal, and heavy soils.  The different soil levels also allow different time lengths for steaming happening.  I can even choose steam for "wrinkle free" cycles too as well as Extra Hot/Sanitize for towels too.  I love the full and complete option flexibility for all cycles and that's a main reason I've always felt WP products are far superior to LG and others because of that intense flexibility.  And that is still the case for the most recent product introductions.

LG had - for quite some time now - 2 steam systems: TrueSteam and Steam.

Steam is basicly saturating the load with as little water as possible, then just heating atiny amount of water under the tub as steaming, then adding some more water and main washing.

TrueSteam uses a seperate steam generator.

Same with Whirlpool: They used to use a steam generator, now they use the tub heater.
Bob's still has the seperate generator.

The small residue being recirculated back on the load when the recirc starts in the rinse is minimal in comparison to rinse water loads.
All that is is the amount of water kept in the pump housing and related pipeing, if it even is half a gallon I would be surprised.

But yeah, I would always add a rinse when using TurboWash on the Normal cycle. Should give you 3 spray rinses and 2 deep agitated rinses basicly.
Spray rinseing is a great supplimentation to other rinsing methods, but stand alone is often not sufficent.

On the topic of the weak spray: Part of the idea of the normal TurboWash cycle is that a high concentration of detergent helps with cleaning in the incredibly short mainwash.
Further, if I am not mistaken, the heater should engage during any TurboWash main wash. Lower water levels there allow the heater to better maintain the water temperature (there's not much time to increase temperatures).
And, lastly, again, if I am not mistaken, many TurboWash cycles should use the spray rinse nozzle during the last minute or 2 of the main wash to dilute the detergent solution , basicly cooling down the load and diluting the soiled water down to more normal wash concentrations before the interim spin.

I had an LG and as it was cold fill only every cycle heated but it also had the steam option which I rarely used. Now I had an issue with it never taking in enough water for the wash cycle and the jets would dribble I attempted to increase the amount of water by adjusting the pressure switch but it would not have it, It did how ever work superbly on other settings and it would allow you to change the cycle so fill on wool or duvet then set to normal cotton 60c and leave it to it, Also the water inlet would cycle on and off really quickly and we had a pipe that clanged every time it stopped so needless to say it was sold on rather swiftly I went back to Miele..

I don't consider the fact that I can't select the water temperature or soil level when using steam. The only time when I'd need it is when the clothes are really dirty, for whites, or when I do bedding on the allergen cycle.

Adding steam to cold clothes isn't going to do anything, the steam will hit the cold tub and condense, cold clothes, and condense, or hit cold water and condense. Forcing hot water is going to actually let the steam work. I'm assuming that LG also thinks that if steam is being use there are some stubborn stains, or exceptionally dirty clothing.

95% of my wash is done on Normal cycle anyway. The only things on different settings I do regularly is the dog's blanket, bedding, and whites.

Well, I've got garments that need the variety.  I got disgusted with most mattress pads that have so much synthetic material in them that a hot was would kill the material used to hold it on the mattress.  I specifically found one at WalMart that stated it could be washed in hot water up to 120 degrees.  Using Normal/Casual, hot, and steam, I can get a 120 degree wash.  Washing white dress shirts that are a variety of 100% cotton wrinkle free as well as some that are poly/cotton, I can still wash them in hot with the same cycle options and I get rid of any potential "ring around the collar".

the LG spray rinse. I've seen it and it looks pretty awesome. I'm guessing the spray rinse is longer or more active on some cycles.

As far as the latest Duets/Maytags with recirculation, I wonder if they spray rinse as well?

Thought of another instance whreby temperature & steam flexibility were paramount.  A friend of mine was visiting and somehow managed to get kerosene, or something similar on a sweatshirt, jeans, and a blanket.  I prewashed the garments in warm.  then washed on heavy soil the load in warm on a cycle where the heater wouldn't come on.  And the scent was dissipating.  I washed again, heavy soil, normal/casual, and warm water with deep clean steam option & 2nd rinse.  Scent was just about gone, but ran through another duplicate cycle just to make sure.  He's very picky about colors remaining in clothes and wanted the scent gone.  Scent was gone and lightly dried and hung up to dry.  He was very pleased.  He thought he was gonna have to throw away those relatively new jeans and sweatshirt.  And no excessive "hot" water either for this lad.  Usually, yes, I usually need steam when it's a sanitize wash temp or a hot wash cycle and heavy soil.
