So what's the bottom line on buying a dryer in the USA that actually reverses rotation equally from one direction to the other? Is there such a creature? It would make sense, since all front loader washers reverse now.

The only one I've ever found that was American was the GE profile dryer with the tear drop door.

I wish I would have never sold that dryer. It was dual motor, so the air flow was never compromised.

I do like the Miele condensing dryer, but a lot of people don't seem to like them.

As soon as I can figure out the circuitry I am going to rebuild a Maytag Dependable care to reverse tumble on a timing switch.

Thank you, that is good to know. I wonder why it is that there are not more of them? It would seem to me that it really wouldn't take that much more to have a reversing motor, even if it has to be a separate motor from the blower. It would certainly eliminate all the balling up of large items.

Fisher & Paykel's SmartLoad topload dryers have reverse tumble, as I have discussed numerous times, but unfortunately were discontinued several years ago so specimens available now are only what may come up as used on CraigsList or at resell shops.  The reverse pattern is 40 seconds of reverse every 4-1/2 mins so it's not fully equal-time for both directions.  However I have found it to be effective for sheets, blankets, bedspreads, and such.  It also reverses on each tumble-cycle during the intermittent-tumble wrinkle prevent function.

F&P's frontload US-market dryers are sourced from GE.  The redesigned TOL model after SmartLoad discontinued had reverse tumble and was surely based on the "tear drop" model that jkbff mentions above.  That feature also has been dropped since the initial model redesign.

As an aside, upon checking F&P's web site a few mins ago, they are now offering a condensing dryer Model DE4024P1 on the US market.  (ETA: The user guide indicates the F&P condensing dryer has reverse tumble on the designated Sheets cycle but doesn't say what's the reversing pattern.)

I have 3 dryers that reverse tumble, a 1997 Frigidaire Gallery (stacked w/ f-load washer), a Fisher Paykel top-load dryer and the little Miele vented dryer I picked up in April.

 

The Frigidaire was my only dryer for about 15 years and it runs about 5 minutes one direction, reverses about 30 seconds, then back.  The blower isn't optimized for both directions, as both the noise and airflow out the exhaust is noticeably less when reversed.   I feel the "reverse - tumbling" was more of a marketing thing as it has little effect on preventing things like sheets from balling up. (photo is a GE badged dryer, but it's exactly the same)

 

It's been a while since I used the F&P dryer, but as I recall it ran an equal amount time in each direction, but I could be wrong.  I haven't run enough variety of loads in it to know if things ball up or not.  I need hook back up and use it again.

 

I don't use the Miele much as it's electric and I prefer gas dryers due to their speed and lower operating cost.  While I haven't timed it, the Miele seems to run one direction about 5 minutes, then reverses for 1 or 2 minutes?  Airflow and noise out the exhaust is the same either direction.  An interesting note, it only has 2 baffles or paddles in the drum rather than the usual 3.

Its nice to see a pic of my GE dryer being used here...that dryer does not reverse but I have had a Frigidaire version that reverse for 20 seconds or so ...with the heater on mind you...and very little airflow...so you can imagine when it reverse back to clockwise tumble, the air being pulled into the drum was super hot after the reverse. That size dryer drum did benefit from reversing especially with sheets and jeans.
My Miele 9800 dryer did reverse and it did so randomly. That dryer did ok but the weak spot is the drive system which uses 2 belts. Anything over 20 lbs of wet wash and you were asking for a broken belt. And having said belt replaced was not cheap or simple to replace either.

Mieles random reversing

AFAIK they have a pretty sofisticatd sensing algorythm tha is supposed to reverse when ever needed.

Works 90% of the time in my experience.

the only thing that seems to have issues tumbling were sheets/blankets....

especially fitted sheets with elastic all the way around....and has no difference with one direction, or reversing drums, those type ball up no matter what...

as a regular load, either dryer works fine.....

Fitted sheets

Having slept on fitted sheets with elastic all my life, I can say that at least on a compact dryer (standard here in the EU), reversing can help. It just has to happen often enough.

I don't have fitted sheets ball-up in the F&P dryer, and not often is even a pillow case found in a pocket of one.

Reverse direction dryers aren't that common in the US. Reverse direction dryers are better for things like towels and sheets, but they have a couple more moving parts than a conventional dryer that has a drum that turns in only one direction. Reverse direction dryers are common in Europe, but I am not sure how well they would sell in the US market.

My Oko-Lavamat Condenser Has Reverse Tumbling

launderess's profile picture
Works well enough one supposes for clothing or other loads; bed linens little less so. That is things like fitted sheets still tend to ball up regardless often enough. Maddening thing is opening the dryer to sort the mess out (if machine does not on its own), releases all that hot steamy air, so dryer has to work interior conditions back up again.

Ironically if one choses "quick dry", the machine does not reverse tumble at all until the "damp dry" portion of cycle. That is when cycle is pretty much already over.

Since one rarely machine dries bed linen this is a minor quibble.

Still have always said things rarely ball up in large commercial or laundromat dryers, and they rarely reverse. Must have something to do with the large drum volume.

I have a Maytag Atlantis dryer and it does not reverse tumble. I have found if a load of sheets and duvet covers is big, no balling at all. If the load is small then sheets etc ball up really quickly and much time spent interrupting the cycle to de-ball, which is very frustrating. So I always make sure the sheets and duvets, or dunas, as they are called here in Australia, loads are big and full to the dryer capacity and they dry a treat without reverse tumble.

I also have F&P front load dryer that takes 5kg load and it fully reverse tumbles and is a great little machine. My preferred dryer has always been the Maytag Atlantis purely for its huge capacity.

The Frigidaire reverse dryer is a joke and the F & P one pretty much is too. They also are both small capacity. I was talking about a real dryer that will hold something and dry it.

Speaking of more moving parts and increased complexity...

What makes me mad with appliances is that American dryers really haven't changed much over the years yet they are the same exact price as the washing machine.

From a retail stand point: A washer costs us the same amount as a dryer. We are charged the same amount to ship a washer as we are to ship a dryer. A washer does not weigh the same as a dryer.

Talk about not getting a good value for the money spent....

Bruce, unfortunate that you've had such bad luck with F&P SmartLoad dryers.  I recently successfully dried in mine a queen-size *very* heavy cotton, thickly-quilted bedspread.  It fits for washing only in my Neptune TL and that requires a small bit of "stuffing-it-in."  The care tag advises to wash in a commercial frontloader.

Which is why I have a nice big front load washer that will wash a king size feather comforter with ease, just wish the matching dryer reverse tumbled. Neither F & P or Frigidaire would come close.

I don't have any king-size beds or bedding, so my equipment fits my needs quite nicely.  The dryer can take a full-size load from any of my available washers.  Wonderful that there are machines on the market that fit your needs as well.  ;-)

I have found that American dryers that don't reverse do tend to ball up bedding.  I think it's a shame that reversing isn't an option as I suspect it might alleviate the balling up problem.

 

My Miele T1 heat pump dryer only reverses for 10 seconds every 5 minutes.  There is no logic/sensing/randomness to the reverse procedure.  It's a good dryer and can dry my American kingsized comforter, but almost always balls up fitted sheets and duvet covers.  I have tried drying them separately and all together but they still ball up.  I had a technician out but he couldn't do anything.  Miele have been promising an update that hasn't happened.  Very disappointing.

 

I took this photo when I tried drying the bedding with towels to see if the large load would help.  I loaded 13 items -- they came out as just 3 items!  The duvet cover had swallowed up 10 items knotted inside it.

 

I have an old Miele vented dryer from the 1980s that rotates equally throughout the cycle 1 minute in each direction.  This never balls the bedding and it dries just fine.

I have an older Miele dryer that indeeds rotates equally. It doesn't happen often that my duvet covers ball up. Only now and then. When I add fitted sheets, it happens more often, so I dry them separately. No problems otherwise.

BTW, when I wash the duvet covers and fitted sheets together in my Siemens washing machine, the whole bunch of laundry ends up in one of the duvet covers rather often.

Miele Professional equipment

Either has programmable reversing or equal reversing, which works wonderfully.

On washers, I found that asymetric drum padles which induce a front to back movement, tend do make tangeling verry likely.
Our Panasonic (VG4 series) was the biggest contender for that.

I'm pretty certain the old Hoover Logic tumble dryers tumbled equally in both directions.

I've a vague notion that perhaps that model had two jockey wheels (edit: it did!). The fan was of the 'straight vane' type too, so would keep blowing irrespective of direction. Tumble action was 37 seconds in both directions.

I have a T1415 Miele that reverses. It's a vented electric model that was discontinued around 2007 or 2008 (i think), but there are similar models out there. It runs for about 3-4 minutes in one direction, then reverses for about 2 minutes. I typically iron my sheets / duvet on a rotary ironer, so I figured out a system that works well when running bed linens. I take the whole load out of the washer, shake everything out, and put it all in the dryer on the "rotary iron" setting. While the dryer is running, I turn on the ironer and let it heat up. When the rotary iron cycle finishes on the dryer, I take out the flat sheet and pillow cases (all of which may or may not be balled up inside of the fitted sheet at that point). The fitted sheet then goes back into the dryer by itself, on a regular dry cycle. I run the sheets and pillow cases through the ironer while the flat sheet finishes drying in the dryer. It only takes me about 5-10 minutes to iron the sheets and pillowcases, and it takes about the same amount of time for the flat sheet to finish drying. Once the ironing is done, the fitted sheet gets folded and the whole set goes back to the linen closet until the next rotation.

Is one has known how to make beds with mitered corners for yonks. Once learned and mastered (back in the days when hospitals never saw fitted sheets and you got one if not more changes of clean linen a day), it is a snap.

As such once moved out on my own have rarely bothered with fitted sheets. This suits since nearly all bed linens are vintage to antique American or French that all predate the invention of fitted sheets.

It seems as though only in the USA can you not get a good dryer that reverses direction equally. I wish someone would come up with one.

Maybe one of the reasons is how MANY americans (specially millennials) to laundry.

Sorting clothes:

Sort the clothes in two piles - What can go to the washer, what won't fit in the washer.

Don't worry about colors, dirt level, lint "donators" or lint "receivers". Tide Pod should deal with everything.

Toss everything in the washer. Whites, light colors, blacks, that underwear with tiremarks, kitchen towels, mopheads, pet blanket, the dog, the cat, the hamster, the ferret, the door mat, etc. If something goes wrong, no problem, you can write a review saying how terrible that washer or that detergent is.
Then select normal cycle or "quick wash" or simply hit power and start, because it's 2017, who cares about selecting a cycle anyway? They should work or we can simply return the washer, sue the manufacturer, without forgetting the horrible reviews.

Then the clothes go to the dryer (if i don't forget the load in the washer for 3 days). toss everything, that's how dryers work. this is USA, our dryers are huge the clothes should dry.

Then there's the wrinkling. after writing a review about how horrible the dryer is and about the clothes that didn't dry, i can use Febreeze wrinkle releaser. if it doesn't work, i can write a review saying how horrible that product is.



In other words... no matter how hard you try to design a good dryer, modern consumers will always complain. so why spend time and money making them reversible?

Also, as they are huge and people mix sheets with small items, the tangling/rolling problem is somewhat naturally minimized.


Because of the F-word millennials I've made a washer with only ONE cycle (and of course i personally hated it). I have a folder with over 300 emails from customers asking me to make a washer that wasn't complicated to use, because selecting a cycle is not "user-friendly". Now i have tons of emails from people that saw the product features and loved to know they can just hit power and start buttons.

Reverse Tumbling Clothes Dryers

combo52's profile picture

After reading this thread so far there does not seem to be any indication that RTCDs work any better than ones that don't.

 

First of all, all dryers seem to tangle fitted sheets

 

Second, If a dryer tangles in one direction and reverses for a while it may or may not untangle said clothing and it has no way of knowing when the clothing is actually tangled or untangled, so at very best it is entirely hit or miss.

 

Full sized dryers like WPs 29" machines [ widely regarded as the best clothes dryer ever on this site ] are built to function running in one direction, trying to make a 29" WP dryer to run the other direction would be stupid, it would take longer to dry and endanger clothing with excessive heat exposure to the clothing. You would face similar problems trying to make a MT SOH dryer reverse.

 

If you think about it the only reason that FL washers reverse is because it is so easy to do and costs nothing to do, and some tangle some loads anyway. Early FL washers in the US and Europe did not reverse and none had any problem  with tangling except models with slanted tubs.

 

Fact: all my vintage combination washer-dryers only wash and dry in one direction, NONE of them have the slightest problem with tangling clothing with the exception of the Easy combo that has a slightly tilted tub.

All European frontloaders have always reversed (perhaps apart from a model that I don't know of). Here's a video of an early Constructa (1953).

Apparently when I dried a moderate-thickness queen-size quilt in a WP 27" (Calypso-match) dryer on the designated Bulky Items cycle and it came out rolled into a wad and still very damp (which doesn't happen in the SmartLoad) was a one-off incident?  ;-)

I'm using my Miele dryer today and timed how long it runs each direction. It runs equal time in each direction, 1 min, reverse, 1 min, reverse, etc, etc.

Philco dryers reverse tumble, but I think the cross vane Westinghouse dryers solve the problem pretty well.

Dryer Size

I live alone. I seldom fill up either the washer or the dryer; I just don't generate that much wash. I don't like, and don't own, any poofy comforters or stuff like that. I agree with others that fitted sheets can be a problem at times. I'm also a very regular user of lingerie bags for wash and drying. So, for my needs, a reversing dryer would be of no particular benefit.

I just got this new BOL Speed Queen dryer, and I'd recommend against buying it. Oh, it's got fine size and though I wish it had a s.s. drum like my 17-year-old Kenmore had had, I really like the lint filter.

The problem with this dryer is that it doesn't have a moisture sensor. I didn't think I'd miss it since certainly in the distant past I had dryers without one. Well, I do miss it. I still haven't mastered, after a bunch of loads in the past month, where to place the dial to get adequate drying without just cooking the load. Oh, I'll learn to live with it--but I sure with I'd thought this out differently.

The 1960s Philco dryers ran the fan backward during reverse so airflow was reduced and I believe the heat was shut off, or at least the gas burner was, when that happened.

 

KitchenAid made a washer and dryer pair for dedicated dealers that featured a stainless steel exterior. The washer was a Duet, but the dryer was a custom made machine by American Dryer Corporation with two motors and it reversed.

 

The problem of tangling was tackled very well by Whirlpool in a few models that have variable speed tumble selected via a lever on the control panel linked to the belt/idler pulley mechanism . Sheets were tumbled fast enough that they did not have a chance to ball up. I have a WP gas two speed dryer that just varied burner input and air speed. On gentle is is great for drying a complete set of king bed linens without tangling. It has a glass door and I watched what happens on the regular air speed. The sheets get pulled against the exhaust grill on the back of the drum which interrupts the tumbling pattern and starts curling the sheets into a ball. On the delicate setting, a damper reduces the air flow and the sheets are not pulled against the exhaust grill. I have had some success with drying a full set of sheets in my 29" WP-made dryers by letting the lint screen get full which also reduces the suction at the exhaust grill, but not as dependably as the baffle controlling the air flow in the two speed dryer.
