Looks to be a 1400RPM model. Is there a reason why all WP Duets sold are now only 1200RPM? The "Whistling" sound indicates to me that it was ramping up to its full final 1400RPM when this took place, it is possible an article shifted or it just went into spin unbalanced and somehow managed to reach 1400rpm possibly loosening the shocks, judging by the position of the tub, the front shocks let go.

Nonetheless, Its good to see Whirlpool stepping up and buying them a new washer and dryer no questions asked...unlike Samsung and LG.

Given that she didn't load it with something waterthight, and that she heared a high whisteling sound, this could verry well be a bearing issue.
Or, thinking about it, maybe its the balancing ring?

However with these stories I am always somewhat hesitant. Such dramatic failures are extremly uncommon for bearings.

I cringed when I saw this story.Thankfully WP did step up and do the right thing. I know there are those of us who hates Whirlpool for "destroying" other companies but I have had good service from all the products I have purchased from them over the years. I hope they correct their problems quickly.

but did Whirlpool respond because of the issue, and will start a recall?...

or did they step up because of KARE-TV 11 News?....

note they didn't respond to KARE-TV right away....as mentioned, they had issues trying to get a response from Whirlpool....

I think Whirlpool should have responded way before KARE-TV even called....

Exploding Top Loaders?

The above comment has aroused my curiosity: are there any recent episodes of top loading washers exploding? Not counting the top and front loading Samsungs...

Post# 966451 , Reply# 7   11/6/2017 at 18:15 by Tomturbomatic (Beltsville, MD)        

It could have been a bearing failure that caused the tub shaft to fail spectacularly like when wheel bearings seize up and cause a wheel to leave a car or trailer because everything gets so hot the spindle sort of melts/breaks. If the tub shaft had broken, it would explain why the tub dropped back, wrecking the machine and blowing bearings all over. That could be a new euphemism for any number of disgusting bodily functions. I wish there had been a security camera filming this. That door boot sticking out looked like it had given birth several many times to oversized somethings.

Hopefully she went to the ER, has everything documented for her pain and suffering and any damage to the house. That is Whirlpool's responsibility too. Heres a new BOL pair to replace that, I dont think so.

Until a few years ago I'd never heard of washing machines that violently disintegrate during the spin cycle. Maybe it's part of the new eco-intuitive design. When the machine decides to terminate itself to make way for an updated, more eco-friendly replacement, it goes bananas and rips its own guts out.

Unless, someone is able to hack these machines from Russia or some such place and make them explode. Imagine millions of washing machines all exploding at once throughout the developed world. Spectacular!

Could have been the balancing ring, filled with steel balls and some sort of liquid. AFAIK these have one at each end of the drum.

I believe there were also two cases in Texas and another one in Arizona and at least one Maytag Maxima (Duet sibling) that exploded.

But I don't have enough details about them, just news like the above case.

Someone will die

We have been over this like at least 10 times by now...

There are literally millions of FLs out there.

There have been lets say 100 cases of them failing in that way.
In at least half of them there was enough doubt about loading, maintanance and other faults that were there beforehand which could have contributed towards such a failure that it was safe to say that it was not manufacturers fault.

In the rest, there was the verry reasonable possibility that it was manufacturing defect.



Before I am scared of dying by unplanned rapind disassembly of a washing machine I am scared of my car airbags or by salmonella.

Our vintage machines donít explode.They usually shut off if improperly loaded. Our old front loaders were often bolted to the ground or were so heavy it didnít matter. Facts are facts. I donít know what German machines do. If they donít explode, good for you. Iím done with this stupid argument. If you all want to carry on about it, fine. I donít care!

Exploding FL's #'s

There have been a total of 5 WP Duets that have exploded. One of which was actually an older WP duet with the belt drive. 5 Maytag Maximas. 2 Samsung FL'ers which have also blown up, 1 LG and 2 GE's as well.

These were sourced from safer products, Youtube, an Amazon review and news feeds.

One GE explosion cited the spider blowing apart during its high RPM spin caused the machine to blow up.

Looks like manufacturers feel they crossed a line allowing these giant-capacity machines and their huge drums spin at 1400 rpm. I loved spinning huge loads of bath linens at 1400 in the Maytag 8100, but often wondered if the stress of spinning a BobLoad at that speed was putting an undue amount of stress on the suspension, etc.

My top-loading Speed Queen spins at a leisurely 720 rpm, but since the dryer reaches temperatures rivaling the surface of the sun, loads of towels dry surprisingly quickly, LOL.

Frigilux

Do you have any idea how hot these SQ dryers actually get? I'm sure my new one gets a lot hotter than my Kenmore I just replaced last month, and it certainly didn't seem lacking.

You're right, though--I was shocked by the heat of the 'normal' heat setting. And I don't miss the higher spin speed of my former front loader, either.

Forces during spinning

www.calctool.org/CALC/phys/newton...

Just a random tool off of Google, perfect for such situations as it supports a lot different metrics.

Just FYI: We here have machines with 1600rpm at drum diameters of up to 50cm (radius 25cm thus) and max rated capacitys of 8kg that I can confirm.
LG offers machines spinning at 1600rpm with up to 12kg capacity. Can't confirm its drum diameter though.

So I don't think that it is much of an issue to make 1400rpm happen with some small structural changes.

Just pondering how many machines self-disassemble that aren't reported and don't make the evening news. There must be others, statistically, not a global catastrophe of course, maybe handfuls more? Without injury or property damage, it would have no "hook" for the news coverage and thus hardly worth a mention in the trivia section of a neighborhood chat board.

Those owners might not report them for various reasons and just replace the machines. Out of warranty, self-blame, etc. I had a friend with a Samsung that flew apart while the service tech was standing in front of it diagnosing a strange noise. It was replaced under extended warranty at just under three years old so it quite likely never made the Destruct-o-Matic stats at Samsung directly.

first of all.....you know the media HYPED up the hell out of what really happened....

look at the size of those ball bearings.....

I have changed my fair share of bearings, yet have not worked on a DUET, plus have just viewed a bunch of youtube vids for the Duets bearing replacement, those bearings didn't look any more larger than any other washer bearing....

does this model that apparently 'blew up' have super size bearings compared to any other machine?

I have seen machines break off from their suspension springs and struts, being able to bounce the whole mechanism and bust into the cabinet......

but in all seriousness, if the bearings broke apart, or the spider snapped, a great portion of the damage would have been to the outter drum, and by dropping out of place, the inner drum would have dragged quickly to a stop....

something doesn't quite add up....

Balancing ring

Martin, that is what led me to the almost certain conclusion that the balancing ring at the front of the tub failed. Maybe a foreign object burst it, or a ballbearing somehow got stuck in a deformed portion and then suddelny loosed up causing a rapid weight shift.
Further, the rear berings shattering would have to pierece a metal sheet or a plastic plate in either direction to even just escape the machine.



You should be familiar with some fluid or even movable weight based balancing system from your Neptunes.

There is a ring around the front and/or back of the drum on the outside, probably fairly sturdily bolted or clipped in.
That is basicly a hollow profile, filled weither a heavy fluid and/or ball bearings of various weights.
I think on some Neptunes the paddles were filled, but that was just weight and couldn't shift much during spinning.

The idea is that after distribution in preperation for the spin, the load in the drum itself behaves like a solid with a given distribution. No matter how high you crank the spin speed, the laundry will stay in the same place relative to the drum.
The fluid and round ball bearings however can still move inside the balance rings. They experience the same forces pressing them against the the walls of the balance rings as the laundry does towards the tub, but they can behave like a fluid and flow even under that pressure.

During the intial distribution, the movement an OOB load induces in the drum causes a force pattern that shifts the contents inside the balancing ring towards the opposite site of where the heavier parts of the load are.
That creats counterforces to the forces the load excerts.

During the extraction process, these play another role.
No load is even 100% even and simmilar, so different parts of the load extract differently. This can cause slight shiftes in weight in the load. These shifts are usually not high enough to even effect the possibility of reaching the maximum spin speed, but they might cause some more vibration at high spin speed swhich the consumer might find annoying.
Otherwise, the only way to completly compensate for these would be to distribute after each spin increment.
The balancingrings however can adapt on the fly, no matter how high the spin speed is. The distribution of the materials in them dynamicly shifts as the weight of the laundry shifts.

This also explains some of the weired behavious of some machines with such balancing rings.
If you let the machine run an empty spin, the drum might seem out of balance even though the drum is empty. This is due the balls in the rings now distributing randonly at first. As there is no force that would guide them into a correct position, they randomly distribute and thus create a possible balancing issue themselfes.
Also, some uses describe that when the machine prepares to spin or starts to ramp up, sometimes, the drum seems to shake violently at first but then quickly and suddely calms down a lot even though the washer just kept ramping up. That is the different weights in these balancing rings distributing and findig the right places to counter the bad load distribution.

One manufacturer here in the EU went to the extend to add a water tank to each baffle which is then filled with exactly the right amount of water during distribution to balance the load near perfection basicly every time.
As there is not one fixed weight used as counter-balancing, it much more accurate and flexible then balancing rings.

Those ball bearings are from the balance rings of this washer platform.

Itís a little unnerving because I have this washer in Maytag wear.

Vintage washing machines are terrific until a part breaks that cannot be replaced. Then, not so much. Of course they do use MUCH more water and usually spin out slower making for excessive drying time expense, but what the hey!

Bruce, My Maytag DG810 can dry a regular clothes in about 45 minutes, and can dry a load of towels in an hour. My Maytag A810 does not have the fastest spin speed, but it does remove a good amount of water.

"One of the many reasons why vintage washing machines are better."

Why is that, or how is that true?

Balancing rings are nothing new, apparently the first patent on them was for a Thor washer that wasn't even fully automatic.

With the demand for ever increasing drum capacities, fast spin speeds and people placing these machines in their "built the American way" houses - sometimes even on the second floor - there seems little left for manufacturers to do but to add balancing rings. I think off-balance controls are already sensitive enough and the suspension struts on US front loaders are pretty soft also.

Very, very few Euroean front loaders have balancing rings (I can only think of maybe a handful of LG and Samsung models), yet the smaller capacity and soild construction of our houses makes vibration basically a non-issue.

THAT is something that has been missing for quite a while with these new FL machines, being able to handle a single item....

when I had the Frigidaire Tall Tumbler, versatility was from washing a pair of single pair of pants or shirt, up to a full load with ease.....

even the Fridgemore didn't have issues....

minimal water use, one way direction washing, could balance the load and take off into a full speed spin with minimal issues.....

compared to todays machines and the playing around they do....

Maytag85

I know and am very aware of what an older Maytag set will do. That was what I replaced when I got new ones. The Maytag washer used much more water, but took less time to operate. But there is just no comparison to how dry the clothes are when they come out of my front loader now. It takes maybe 20 minutes tops to dry a very large load now, since they will hold about twice what my Maytag's did. That really does save a great deal of energy cost.

My Duet took eight attempts to balance a single large towel.






There is currently a full playlist of YouTubers who are challenging their washers to spin a towel on the highest speed. I think the least attempts were done by Miele (vintage and brand new) with three tries and the highest number must have been around 15 attempts.

Getting this out there

I've washed and spun waterproof items in my WFW72 at full 1200RPM with no issues of the machine blowing up.

Further, i've also washed and spun large comforters and king size duvets at 1200RPM with no explosion either.

Now on a different topic, the WP's that have been blowing up are the exact same ones in the category of a very certain spin cycle issue...I think you know what I'm talking about. It's happened to my duet along with some members Maxima's here too. That alone may have something to do with sensing something incorrectly prior to the spin cycle and the machine missing out on it. These WP's prior to spinning do a mini low rpm burst after balancing the load, sometimes it DOES skip that mini burst if it notices the load has no anxious movement. HOWEVER, there are rare loads where it skips the mini burst because it LOOKS like the load is balanced, but when it ramps up the tub moves violently even after the initial thrashing point of the tub.

IMO, if the machine surpasses and manages to get to 1200-1400 whatever max RPM, it MAY (or most likley, may not) pose a condition like this.

Judging by poking around, this has happened to basically every brand. Of course it would be higher on WP's side because they export more machines on a daily basis due to Maytag and Whirlpool being well known brands. Even an LG WM4270 has blew up during its high rpm spin.

But that IMO also doesn't give an excuse for them to be let off the hook. Sometimes I personally wonder if WP even knows what going on when something like this takes place. And if so, is that the reason why all their FL's now are 1200RPM?

I'd like to believe that. I really would. But, i came across a WFW70HEBW which has a max RPM of 1200RPM which looked to be the worst explosion I've seen out of all WP's.

Whirlpool does take a step in the right direction by replacing the units.
But another right but necessary step is STUDYING why this happened and to find ways to avoid this in the future. The best way to do this is to take the destroyed unit(s) and examine it and find things that each model had in some form relating.

I mean after all, look at how people react to Samsung washers now.
I bet their afraid of even walking up to them.
And rightfully so.

Is it not funny... A unimatic spins at 1140 rpm and even though they are sixty plus years old I never heard of one flying apart.
Neither have I for that matter or an early 1140rpm GE or any Rapidry Frigidaire through the 60's.

IIRC, Combo52 has mentioned someone's Unimatic destructing during spin

I know that story and I just reconfirmed with it with the person who witnessed it. The machine did not self-destruct, it was a new vintage find and it was put into the spin for the first time in many years. The rubber mechanism support had dried out to the point that the braking forces (once the machine's power was cut) had ripped it sending the tub into the side of the cabinet during the 20 second break period. This made for a very loud screeching noise, but the machine stayed completely intact and did not break apart in any way like we've have be seeing with a some of the recently made machines. This isn't even a remote comparison of what we are seeing in the news.

It is curious how when the Alpha platform of WP MT washers came out, they were 1400 rpm max spin.
Of which one I got; an MHW5100.
And a mere few years later, they changed all of them to a max of 1200 rpm.
Maybe 1400 was just too extreme for the platform?

In all reality, I'm quite sure the engineering team at WP is aware of any issues, no matter how remote. It's just whether the accountants or management will let them deep dive into it. And they of course would NEVER say, for mostly legal reasons.
It's the same thing at every company I've been at.
Engineering is almost always aware of field issues. Maybe not right away. But if it's more than a dozen that pile up in a short period of time, we all find out some way via customer support.

I'm only guessing, and not speaking for WP, but their component Factor of Safety limits might have been too narrow for the piece part price they're allowed to use. So the simple thing was to limit down to 1200rpm, while not losing extraction performance too much.
Only thing they lose is maybe a black eye in marketing for not having such a high comparable spin rate.
Anyways, their drums are fairly large in diameter, so I'm sure the g-force is good enough.
My clothes are pretty decently spin-dried on Medium spin anyway, which I think is around 1000rpm on my machine.

Unimatic1140, one of the reasons why I prefer traditional top load washers is they plain work, and do what they are supposed to do. My Maytag A810 washer and Maytag DG810 gas dryer has given me little trouble at all, and the only repairs that I need to do is replace the belts on the washer, and replace the drum belt on the dryer, and those are the only repairs that my Maytag washer and dryer needs.

Unimatic Story,

Well that proves it! Today's machines are under-built and that is undeniable. Unimatics held together just fine while sending a load to 1140 in 10 SECONDS and models today with 50+ years of "technology" and "progress" are so figity in balancing a large bath towel but somehow come apart violently after taking 10 MINUTES to distribute and initiate a final spin and still end up on the low speed spin instead of 1200. What happens if the out of balance sensor fails. Lets hope models are fail safe and don't let the machine operate at all, lest this could happen.

Also w/ the Unimatic, everything stayed together with it's minor incident and didn't send 25+ parts flying everywhere. Manufacturers could do better but choose not to on rational of cost and consumers are unfortunately willing to settle for unreliability. I won't however knock FL wash-ability. HE TL has the worst of both, poor washing and terrible build quality.

Speaking of spin speed: after the 1200 rpm spin, I put that towel into my spin dryer and spun it at 2800 rpm. Almost no extra water was extracted. Even a full basket of heavy times like sweaters or towels only releases about a cup of water after five minutes in the spin dryer.

So no have to agree with John: 1200 rpm seems plenty fast.

John-- I'm late to the game with this post, but here's the information I found concerning the operating temps of SQ dryers.

Reviewed.com's tests noted that both the Delicate and Regular/Normal cycles ran quite hot. The ideal temps are no higher than 140 for Delicate and 151 for Regular/Normal. Both exceeded those temps in their tests. Unfortunately, they did not list the actual temps reached by the SQ. They also noted that the dryer continued running long after the load was dry, which aligns with my experience. It's the trait I find most annoying about the dryer.

Consumer Reports noted that the Delicate temp ran higher than the preferred 140 degrees.

I am all game for the higher spin speeds.....

what I noticed with a lot of them, is TIME!....I found it odd for a spin to hover around 800rpm, then burst up to higher speeds, for 60seconds or so, and then return or back down to a lower speed for the remainder of the spin time...

my Neptune 5500's ramp up to 800rpm, and stayed there for the entire spin time....

the first Fridgemore I got did the same.......several generations later, they started with the stepped spin, highest speed was for 60 seconds....

curious, what do your machines do?

The LG turbo wash steps up to 1300 rpm gradually but stays at that speed for quite a while. In fact, choosing the "extra high" spin speed adds about 2 minutes to many cycles.

My WP WFW72 also went for the full 1200RPM and stayed there for about 10 or so minutes before ramping down and finishing up. The only time I ever heard it ramp down to 1100RPM from 1200RPM was on certain odd occasions of spinning a comforter...interesting (most of the time it got to 1200 without ramping down during comforters).

As well as my current MT Neptune 5500. The only reason I think they ramp up beyond a certain RPM in the last couple minutes is to avoid fabric damage.

On LG's towel cycle, it spins on 1300RPM for the full final spin if you select extra high (correct me if i'm wrong). Another thing which is interesting to me is how LG FL washers, if a high spin speed is selected, it'll spin at about 900-1000RPM for most of the spin and then ramp up to near 1200RPM towards the last couple seconds, but then you have WP's FL's spinning at 1200RPM for the full spin cycle...

Spin duration

I can't say that I have ever known of any fast spinning modern frontloader over here, to immediately leap into high spin and stay there for the duration of the spin cycle. That would quickly lead to drum bearings being worn out.

What I do know, is frontloaders tend to go through the speed range, monitoring the imbalance as they go. Usually the machines spin for a much longer time at the lower speeds. Then, they might hold the timer at that point, and redistribute to rebalance the load. It's not unknown to have the machine detect an imbalance and lock the spin speed at low revs - even after attempting several redistributes - making the best of a bad load. Some might even abort the spin altogether.

I've also seen the opposite behaviour, where if managing to balance perfectly, the machine will jump its timer onward, skipping minutes in a matter of seconds. But even so, the machine still spins mostly at lower speeds. Final fast spin only lasts about a minute or two.
