LG Front Load Washer

[trappn]

Memorial Day Sale..........

poweerfin64......Our understanding is LG will announce some holiday discounts on the 20th. That's the only thing we're waiting for. Our local Lowes has the WM4200 marked down to $1099, but only in black.

We'll probably end up getting the dryer, but haven't made up our minds. Either way, will be holding on to the 29 inch Whirlpool.

mark.....We're sure there's going to be a steep learning curve. The way the AI marketing sounds, we throw the clothes in the machine & push one button. I'll bet there's more to it, but we can't wait to learn. We're excited about LG's rinsing performance. Our 92-series SQ is not the best rinser. Thanks.

I believe the spray rinse occurs on most if not all cycles. I know it happens on the normal cycle and the towel cycle for certain, I've seen it happen.

I'm also interested in the 'AI' that LG has put into the 4000 series. it seems interesting but dont know if it works well.

as for the dryer, i'd get it. ours dries well, and the steam function is super nice to have, especially for towels & dress clothing.

spray rinses

are on most all the cycles, including the down loaded cycles also from the ones

I've used so far, and do after the main wash and rinses. They aren't really

long but does help!

the AI is only on a few cycles for the washer, normal, bright whites and Rainy

Day from the down loaded cycles, I think there is 1 more also, can't remember

for sure which one. I do like the AI feature. Wish it was included on more

cycles. The Dryer, AI is only on the Normal cycle.

question

How does AI work on the normal cycle on each?

 

[trappn]

AI........

So far, I thing we should all be able to agree that AI is still in its infancy stage when it comes to washers. That's one of the several reasons why we chose to not to go with the 4500.

 

[eurekastar]

On AI cycles, does the machine automatically dose the right amount of detergent and other additives? 

 

[gelaundry4ever]

good question

I was gonna ask the same question. I use laundry detergent and fabric softener. The only time I use bleach is for whites.

 

[appnut]

Bill, yes, AI coupled with the EZdispense system does allow correct dosage of load based upon paraameters sensed by the load and settings.

 

[trappn]

Well.......

......we could be wrong, but seems like LG has relied on the cycle that is chosen + the weight of the clothes for quite some time.

Now, it seems like "fabric sensors" mounted to the drum help the machine to calculate everything else.

At this point, as engineers, we're not completely buying into all of this; but, we're willing to purchase a reasonably price WM4200 as a test bed.

If LG, or any other company, can find a way to sense "all fabrics.," then., we will be all in. Thanks.

 

[egress]

I'd love to see a teardown video of one of these new machines.

yes, but on 4500 only. 4500 has the EZ dispense for liquid detergent and fabric

softener, 4200 model does not have EZ dispense. AI detects fabric types and

weight, size of the load, and calculates time needed, wash motions for the cycle,

4500 model determines amount of liquid detergent and fabric softener to be used

for the load, which can be adjusted to the users preference.

 

[egress]

of course. I'm guessing the auto dispense isn't anything special, probably just a pair of peristaltic pumps. the fabric sensors are what I'm really interested in. I know F&P has done fabric sensing for a while, but I think they're the only company that has until now. LG's normal sensing determines the weight and also water required (does this by filling, then tumbling and filling again when the water level drops from clothes becoming saturated). I think the only new thing is of course the fabric sensing and maybe a smarter choice of washing motion.

AI

Oh, the excitement it brings.

I think Fuzzy Logic was introduced here in the 90s, when washing machines and dishwashers could do load-sensing. So almost 30 years ago.

I remember washing different loads in my grandma's washer. Same cycle but one load synthetics, the other towels: you'd get different cycle times, wash and rinse water levels, different tumbling and different spin profiles. It didn't mention AI anywhere - it was just current technology from the early 2000s that Miele used.

Rant about everything being "AI" these days over.

AIDD

Calling it AI is branding nonsense, but you can't compare it to Fuzzy Logic.

The AIDD - at least in Europe - changes stuff like tumble patterns for different cycle steps depending on fabric type.

For example, during heating, depending on load type, tumbles could range from gentle swing up to distributions.

The recirculation would have different duty cycles and be used differently.

All that not actually dependent on fabric type, but on its actual consistency.

Towels would get different treatment from jeans or sweatshirts.
Both are cotton, both are heavy, both absorb a lot of water.

But jeans and sweatshirt are stiffer so to speak.
They tend to be less good at water exchange, so more distribution for even heating was used.

Towels would get more tumbling but more recirculation.

So there is something to the technology.

 

[gelaundry4ever]

personally

I'd love to see a full default normal cycle of the 4500 with laundry detergent and fabric softener in the designated ez dispensers.

spray rinses

They are performed on all cycles, except Bulky, as long as TurboWash is activated, at least on my machine and the WashTower I have used.

 

[powerfin64]

lakewebsterkid

what is your washer model number?

 

[launderess]

Fuzzy Logic....

Or whatever you want to call it one loves it with modern washers.

Older Miele was doing a number on our finer linens washed in "normal/cottons". Heart broke each time water changed and drained seeing bits of linen coming out of hose and being caught by filter.

OTOH both my Lavamat washers treat linen far more gentle in "Cottons/Linens" normal cycle. Machines do sense difference between loads of all or mostly cotton or linen and drum rhythms and so forth vary accordingly. Things get better if "sensitive" option is added as well.

Result is even after a nearly two hour long cycle in AEG washers drain filter has virtually nothing.

 

[appnut]

I just observed a YT video with the WM3900 Towels Cycle with Turbowash360 and at best, I think I observed a spray rinse on the spin between the 1st and 2nd deep rinses, but I don't think I saw it do spray rinse on the pin right after the wash or the final spin.

 

[powerfin64]

I can say mine does a spray rinse on the first spin after main wash, and spin

after all rinses. (4200 is classified as advanced tier efficiency.) Models

3900, 4000 are tier 2 efficiency.
