Dryer

I much prefer our Duet dryer over the LG Dryer we have in the house now. You have to use either Normal or a higher heat cycle to actually dry anything. I don’t find that it runs hot enough. Not sure why. Permanent Press on Very Dry does not fully dry. The longer cool down is welcome, though not effective enough. I have had the same experience with other LG dryers I have used as well.
 
The Emperor Has No Clothes........

Once again, two (2) engineers attempting to peacefully co-exist in the same household.

We sort of like our new LG dryer; but, would never choose to love it (as, it is currently programmed.)

We sort of love our LG washer for a number of reasons; but, we don't believe LG buys in to steam as an effective option for stain removal.

We like one or two of the dryer's steam options; but, would never advise anyone else to depend on these units for wrinkle-free clothes.

To be sure, the LG dryer has the capacity to handle our California King bedding;
and, the dryer's steam options are useful under certain circumstances; but, the LG dryer, in our opinion, offers no real benefit to anyone outside of it's superior capacity.

We already know that politics rules most things on this site, but we just couldn't mange to contain ourselves.

Well....dryers

are sort of unexciting appliances - like a refrigerator or an oven (for me, anyway).. The action is in the clothes washers and dishwashers.. But I guess you could LOVE a dryer/refrigerator/oven if they perform well.

I hope to have an LG turbo wash when/if my Duet ever dies....But whirlpool classic dryers are my favorite.
 
That LG TurboWash feature that my washer has is quite effective I must say. The 3570 washer that I had only used two jets at the 4 and 8 o'clock positions and it was effective. But the 4000 washer that i have now has the TurboWash 360 and it uses two additional jets at the 10 and 2 O'clock positions and if the load is big the lower jets can sometimes get drowned out, but the top jets throw quite a bit of water on the load all the way to the back of the drum. and

I agree that dryers can be kinda boring but the LG dryer does the job well and is very well made I might add. the Whirlpool dryer that I had for a year, the drum itself was out of round so when a load was drying in would thump and the dryer was much louder than the LG. The Whirlpool dryer was not as sensitive as the LG dryer with the sensor drying. If the LG dryer senses that the load is already dry or that there is nothing in the dryer it will shut off within 5 mins...the Whirlpool, not so much. The LG dryer is much faster drying a load...think Maytag Stream of Heat ...the original design where the opening was in the upper right corner of the drum, before Maytag put the opening in the upper center of the drum. Plus the LG moves quite a bit of air thru that drum at 220 cfms...
 
220 cfm

I still highly doubt that number.

That would mean the whole drum volume would be exchanged every 2 seconds.

Further, some rough back of the napkin math leeds me to believe that would mean the 5kW heater could only raise the air temperature by not even 40C.

I know I read some service literature somewhere that sad that.
But still don't trust it.
 
Mike, I keep forgetting to tell you this, but it looks like the downloadable cycle Jumbo Wash has the same cycle demographic as Bulky/Bedding, but it adds the option for a high speed spin rather than limiting to just medium.
 
The majority of the dryers here in North America are vented dryers, not heat pump or condenser dryers like what is available on the other side of the pond. Those dryers are also much smaller drum wise. Miele compact dryers come in at a cool 4.6 cuft if that and the mega Miele dryer was just 6.2 cuft and that dryer was pulling up to 275 cu ft of air a minute and that dryer had a hard time drying a load no matter what was dried in it and the load had to be spun at 1000+ rpms in the washer. I did an experiment once and used my Maytag 613 washer that spun the load at 618 rpms....the load was tossed into the Miele T9800 dryer and took well over 2.5 hours to dry.
Anyways, the LG dryer has this neat feature where I can turn the drum light on when the cycle starts and I can see the load billow open with sheets , T-shirts and other items when the load is being tossed into the airstream. I have seen dryer sheets ride the airstream on small loads, so yes i do believe the 220 cfm specs. The heater for this dryer is in a tube at the base of the dryer on the right side so there is plenty of time in the tube to raise the air temp...
 
I know that manufactures throw around these huge airflow numbers.
Yes I am aware that these vented dryers are huge.

Just on paper, there is simply not enough energy there for heating at those massflows.

So, 220 cubic feet per minute convert to pretty much 6330 liters of air per mimute.
That is just about 105l of air per second.
105l of air weigh almost exactly 130g.
The energy needed to heat 1kg of air by 1K is just about 1kJ spot on.
So, to heat the amount of air flowing through the heater per second by 1K/1C/~2F, you need about 130J.

The heaters in these are roughly 5kW.
5kW translates to 5000J per second.

So, the heating energy available can only raise the air temperature by a maximum of 5000/130=~38.5K/C or ~77F.

No heater design or anything can change basic thermo dynamics.
If it only produces that amount of energy, that amount of air can only get so hot.

And 77F above ambient is maybe just shy of 150F - and these dryers can from my knowledge get quite a bit hotter than that.

And as they don't have a variable speed blower, 220cuft just don't make sense on paper.

That doesn't mean they aren't good dryers.

It's just that number that just seems off.
 
The heating powers for refference

LGs smaller commercial offering has 5.4kW in electric and 5.8kW in gas; the larger one has a whopping 16kW and is only offered as gas.

Mieles offering is 6.15kW heating power and only available in gas.

For comparison, Mieles 9cuft commercial units can be shipped as either 13.5kW or 27kW electric (the latter one is new to me, but anyways) or as 15kW gas.
The electric version claims to be about 305fm and the gas one about 365cfm.
For comparison, the same unit can be equipped as a heatpump system running at 4.9kW system power converting that to a nominal 10kW comparitive heating power. That seems rather inefficent for a heatpump actually - though it apparently is still about 30% more efficent though it takes basically exactly double the time to dry a load.
 
As of this morning, I have completed the adoptiion of the other child, an LG WM4200. The Duet began developing the problem where it had extreme difficulty balancing and wouldn't go above medium spin speed at best. And this was even when it was completely empty several times. I've seen this problem mentionned several times and at age 10 years, I wasn't sure I could tolerate it. Took 1.75 hours to dry a very large load of towels. And HD had an even lower sale price than the pair did when I bought the dryer in August.

Right now I am having my own wash-in, running several loads of clean old towels.
 
Welcome to the WM4200 Club!

Glad you were able to get the matching 4200. You will find it's very quiet and does a great job with your laundry! alot of neat features on them.

Enjoy!
 
Jumbo wash

that's awesome. It's bulky cycle but not limited to medium spin speed. Is this downloadable for all LG washers that have turbo wash?
 
Well let me sum up my day yesterday. I'm over the moon. A former member and I have been emailing off and on since 2009. He knows how fascinated with cycles and how things progress. He shared with me some intricasies of his WM4500. What I learned from him is with these LG's you can start a cycle and have it do something you want and then pause it, chaange to another cycle or even modify/change wash temperatures, number of extra rinses, soil levels. Contrary to my Duet, chnging cycles doesn't cause water to drain out and cancel the cycle. Let me say, firstly I wasn't too thrilled about water temps for Normal cycle has Warm wash being 86F degrees and hot being round 95F to 100F degrees. Other cycles, target temps for warm is 90F and hot is 113F. 113 for hot is pathetic. But now, I can start out the cycle for extra hot temp and monitor temp with the delay wash & then temp button to show temp in C. I did this yesterday. I can also set up an actual true profile wash. fill with cold or col water and let it tumble for about 10 or 15 minutes with heavy soil on Normal. Then switch to extra hot so it begans heating. And when it reaches the temperature I want, then change the cycle to Whites, Towels, Perm Press, ... Yesteerday when I watched heating starting on Extra hot, I let it go through the whole cycyel. I maxed out all optionns. Starting time was 2:51. At 1:30 the wash cycle finished Temp reached a peak of 156F. I'm still wnting to experiment and see how hot temp will geet with light soil level. I'm so thrilled to have this control that's similar to the Duet's ability to select Steam for Stains and it fills with warm water and heat with the heater heating the wash water gradually hot and sanitize levels also in combination with steam. Now I cn be a button pusher again!!!!
 
@ appnut

Forgive me for maybe missing something. So you now have an LG washer? I know you had said you have the dryer, but I thought you still have the Duet washer.

I hope I comprehended what I read correctly. LOL
 
Ya sorry I thought I had read most of this post but scrolled to bottom and missed the post where you said you got a new LG washer....

You seem to like it so far from what I gather. Where did you buy it? Did you buy water hammer arrestors? I ask because since LG's turn water on/off many times I hear you should get them....How do you feel about the cycles you've used so far in comparison with your whirlpool?

Unlike you - that would drive me crazy to have to do that to get a profile wash. The hot being only 113 is a bummer......So....say you use Jumpo wash, high spin speed, hottest possible (maybe you can't choose extra hot on that cycle? I don't know) I'm sure I have more questions but I can't think of them ATM
 
hammer arrestors

I have the same model, and I have hammer arrestors on mine, but the new models don't do the "pulse fill" thats with older models only. The hammer arrestors do help/stop the pipe banging when filling.
There isn't a Jumbo cycle, but there is a "full load wash" in the downloaded cycles which I have used a few times and can choose different options for it.
 
Mark, I'm not going to need to do a profile wash daily or weekly. Another approach is to do a cold prewash and then have it followed by Normal cycle with the extra hot water temperature. But I like the flexibility and being in control when I want the machine to do something I want or need it to do. It's nice knowing I'm not locked into a whole cycle from stat to finish. That I can make chnges on the fly so to speak and not cancel a whole cycle in the process. If you haven't figured it out, I love options and flexibility choose how I want loads of clothes or dishes done.
 
OK....... Say you do a prewash........then pause, turn to normal....what happens? Does it start a normal cycle as if it thinks it's started with a dry load? Also, say you do choose normal, is Extra hot an option that can even used on normal? Or is that restricted to the allergen or sanitary cycles?

Aside from that - how do you like the turbo wash function? Cuz I know you sat in front of it and watched it like I would. lol
 
pre-wash on normal is selected at the beginning of the cycle BEFORE you press start, and can be selected on most cycles. Extra hot is option for normal and a handful of other cycles.
Mark, your really overthinking it waaay too much. It's basic simple operations.
Select your cycle, options, press Start! ITs' smarter than you think! it will tell the dryer what cycle to use! GASP!(you have to have the matching dryer for that to happen, just so you know.)
any other questions???
 
Mark, I"m not sure I'll ever need/use Sanitary or Allergene cycles. I mean, extra hot and highestt soil level brought wash temperature to 156 degrees farenheit. I think the actual sanitize cycle eaches 160 degrees farenheit and Allergene is like 165 or more with steam injected. One thing I don't like is if you select steam, all soil level optoins are then deemed not available.

Rich, please email me. I have a question I need to ask. Thank you
 
4200 Tub

Is the 4200 tub angled slightly down like the early Neptunes? I believe I saw a video on YouTube some time back that said it was, but just wanted confirmation.
 
Yes the drum is tilted a bit. The water pools into that back area and the load tends to migrate to that back area for the spin cycle. My 4000 washer uses plastic drum vanes to tumble the load front to back to prevent tangling and it works well. The 3570 washer was a beast tangling long sleeved shirts to the point of almost roping….drove me nuts having to dump the load after the cycle was done into a basket to untangle the load before hitting the dryer.
