I've been wondering this for a while now, and I couldn't remember the password for my old account on here, so I had to create a new one to post this.

I recently saw a court document about Whirlpool's initial invention and troubles of the dual action agitator in 1972, and it popped the questions of; When did Whirlpool (or Sears) designers initially conceive and start designing the direct drive system, behind the scenes? And what design configurations did they originally come up with before building the prototypes? Or is this all unknown? If anybody has any information they'd like to share, feel free to, I'm very curious about this.

Anybody have pictures of any 1980-1982 Whirlpool/Kenmore direct drive rear motor washers they'd like to post here? Maybe even a video? I'd love to know how the spin drain transmission sounds on those at the start of the drain cycle. Either way, I'd love to see them. I know about searspartsdirect, but I'd like to see the machine as a whole to really appreciate it's design.

Thanks in advance!

Steven

The Origin Of The WP DD Design 2000 Washers

combo52's profile picture

Great idea for a thread Steven.

 

As a WP authorized Servicer in the 70s we often heard rumors that WP was working on a heavily redesigned washer, we know that it was ongoing by the early 70s. The project was referred to as  LEAP I forget what it meant.

 

WP knew that a more modern, better performing, more reliable less expensive to build and easier to service AW washer would have to be built if they were to continue to be the largest builder of AWs in the North America.

 

The DD washers accomplished all this and more after just a few problems, the biggest of which was the cost saving idea of having a spin drain and taming the aggressive agitation with different agitators and wash speed options.

 

The DD washers went on to be the most produced, reliable, easiest to service, longest lasting and best performing traditional Top Load  AWs ever in North America.

 

They lived up to the vision of Whirlpool Engineers of being US designed and Union Built in Ohio.

 

 

PS, we have a late 1981 WP DD washer all restored and hooked up at the museum that you can come see work [ bring dirty laundry ], the spin drain does not sound any different than any other DD washer, you can throw any DD into spin with a full tub by opening and closing the lid at the start of spin if you like [ doing so will leave more lint and loose dirt particles in your clothes however ]

That answers a couple questions, although I tend to get very analytical about stuff like this, but beg pard. Since DDs are my favorite machine, and are a thing of the 80s, 90s and up, I like to think they were technically around in the 70s as well, alongside their awesome BD predecessors. If it started in the early 70s, I would surmise it was around the same time as the DA agitator invention (1972).

A couple questions I ask myself which are probably unanswerable are:
*What did the whole motor, drain pump & transmission ensemble look like in the early stages of development? I'd guess probably nothing like what was actually built after the completed design.
*And what year did they complete the final drive train which became the machine we all know today?
*And did they ever design a Kenmore DD with the 1970's control panel, whether it'd be a fully built prototype or just a blueprint sketch?

I can't really seem to find any info on this from google or anything, so I figure what better place than here!

John, thanks again for your reply. Very much appreciated! I would LOVE to see your washer museum, but unfortunately I can't travel that far from Idaho right now. Maybe sometime in the future if I ever get the chance?

This is a very interesting agitator to me. Lint filter unit off either a 10611 or 11611 model Kenmore. Barrel fins don't go all the way up like a regular Kenmore straight vane. I've never seen the one without the filter (model 11671). I had only seen this agitator for the first time just the other night!

I think it was 1987 when I got my first washer, which was a low end Design 2000. I had just bought my mobile home and my employees got a collection together for Christmas, and it was enough to buy the washer, $325, I sprung for the matching dryer. I remember looking at really inexpensive Frigidaires and the salesman said it would be nothing but problems and showed me the Whirlpools. It sure did look nice with the black and chrome. It was a single speed, lint filter agitator model with neutral drain. Was a touch rough on clothes but worked well for many years. Sold it with the house in 93

If you want to see an early version of a direct drive mechanism, look at a POD when Easy showed a cutaway version of their direct drive washer and you can see the juncture of motor, transmission and pump.

I like the DD KA machines because of the round tub opening and the fact that the machine can be made to spin drain. My KA machine is a great washer. The slower agitation and the larger agitator fins were gentle on fabrics, gentler in fact than the WP Duet I had briefly. I almost always used the wash water twice to help the water efficiency and I pumped the rinse water out onto the plants which saved some newly planted plants during a hot summer drought.

I remember in the 80s

At our local Sears store , when these were introduced sevearal employees bought up the last of the belt drives because they figured the new washers would be junk, they were dependable but I hate them ALMOST as bad as I do Maytags, my second least favorite washer ever made, a DD Whirlpool /Kenmore.

Sears began rolling out DD washers in like 1984 or 1985. A coworker and his girlfriend initially rented a house here and they'd been together since like 1984 or 1985. When I looked at their Kenmore 70n series washer, I opened it up and looked in and it looked a bit strange to me. What I later realized was I had been looking at an early DD style washer. The control panel was the typical 70 series center dial Kenmore and I thought the agitator was strange looking.

Sears had KM DD machines in 1981, maybe late 1980, before WP offered them.  They were touted as a new design, different agitation, faster spin, compact size but took a full-size load.

The first WP Design 2000 model we sold @ the WP dealer was model LB5500.  Model searches match on LB5500XKW0 (1982) and LB5500XLW0 (1983).

I recall one of the DD deliveries, to someone I knew (she was a library aide at the school).  Ted and I rolled the machine in, got it settled.  Upon ready to leave, he mentioned to her that Sears had been selling the new style for a year or so.  Lillie, who didn't have much of a verbal filter, immediately commented "Probably cheaper .... Ohhh, well, thank you!"  Ooops.

Granny's LA7400XMW2 was bought in 1984 (S/N 35th week 1984).  It was still spin-drain and had the clothes guard ring added.  DD had been out on the WP label for a couple years.  Granny needed a new machine, I went to the WP dealer in her town (Brewer's Plumbing and Appliance) and asked for one.  The fellow got snippy, said he doesn't and won't handle those crazy things.  I told him OK fine, I'll go somewhere else.  I went to the dealer where I had worked and she bought the washer and also a refrigerator.

One Of The First WP DD Washers We Trained On

combo52's profile picture
Was this LB5500XKW0 Ser # C12301087, It was built the 23rd week of 1981, it should have been the 1087th off the line in that production period.

WP brought in 6 of these machines for us to train on, none of the older techs liked them, but Jeff and I immediately could see that these should be great machines. WP used all the tried and proven items from the old BD washers in this new machine.

It used the same spin tube and bearing and seal design, same agitator shaft and agitator attachment system. Same sand cast cast iron transmission lower housing.

We were pretty sure they had a success on their hands.

We bought all six machines that were used in training and sold them to our customers and had no major problems.

The following pictures are one of the original 6 that we got back from our customer after about 20 years of use and I wanted to completely restore it while we could get any needed parts, it is now living at our museum hooked and ready to wash.

Does anyone know approximately how many DD washers were produced?  It would also be interesting to know how many are still in service but I suppose no good way to determine that.

Number Of WP DD Washers Produced

combo52's profile picture

Almost ten years ago the number surpassed 100 million, they went out of the majority of WPs top loading production in 2010, but continued in their 24&27" top load stacks till early in 2018.

 

I would guess that the WP DD machines were easily the most produced TL washers ever in North America, it would be only a guess how many are still in use, but probably 50 million or 50 times more than dependable care Maytag washers that are left in service.

One only has to look to CL to verify your numbers, John. I cannot find anything but DDs anymore all other traditional transmission type TLs have long since worn out but the Whirlpools.

I posted a while back about how Whirlpool was taken to court by GE and Maytag in Canada about a patent issue regarding the dual action agitator. In the court case there is a paragraph about how Whirlpool was researching dual action designs, with one of them being a direct drive machine that had its own auger drive shaft. Meaning the auger in the dual action agitator would not have dogs to cog it around, it was powered by the transmission. Neat.

Thanks everyone for your replies, I've been busy these last couple days so I haven't had the time to respond.

John, thanks a BILLION for the pics! I never knew how much different on the inside that one is compared to a later model WP. The tub design reminds me of that off an older Norge. Is that the original fabric softener dispenser?

I agree with chetlaham, a YT video would be nice. Who knows, it might even get a lot of views, just look at the view count on some of the other washer videos on there!

That looks to be a KitchenAid softener dispenser per the chrome trim.

LB5500 (and granny's LA7400) didn't include a softener dispenser but one could be added.

"Concertic shafts? Never did happen." It did, in an experimental prototype that was never released to the market in the 70s. Read the link below.

 

Whirlpool when designing the dual action had concentric shafts where one shaft powered the agitator base, oscillated, and the other shaft was constant drive and powered the auger.

whirlpool direct drive

I've been wondering about the engineering and what went into the entire project for sometime. my former babysitter had a whirlpool direct drive which agitated at full speed the entire time during the regular cycle. I remember the low F tone coming from the motor during high-speed agitation which sounded cool. It had that chunka chunka sound.

I disliked that

chunka chunka sound. No doubt the gearcase clunking at the short stroke left and right throw limits. The thin light housing probably excentuated the noise. The motors were mainly quiet. The only cushioning was from the flexible coupling, similar the that found on the steering columns of Saginaw collapsible ones in 1965 through '96 rear drive GM cars and trucks. The motor mounts horizontal, and the gears transfer motion to the agitator shaft vertically.

whirlpool design 2000

I've always wondered what became of the platform. They do have an interesting humming sound during high-speed agitation. On the models that were made during the 90s models, some of them had a low f droning on full-speed agitation.

My new ‘63 Whirlpool has a very pronounced woo woo sound it makes when washing :). Unfortunately the hose that goes from the pump to the lint filter broke on me but hopefully I can get that fixed tomorrow since I picked up a new rubber hose at Home Depot today that will work. Will be up and running again later this week and this is the first repair to my new ‘63 Whirlpool Imperial Mark XII washer

Woo-Woo Sound From Belt-Drive WP Washers

combo52's profile picture

This phenomenon only happens on models with the regular 1/2" wide notched belt, on the machines where it is most pronounced the belt is usually a little too lose and often worn, it is really a sign that the belt is slipping a little and probably should be replaced.

whirlpool sounds

are unmistakeable to me. I too love the woo-woo sound. Did anybody catch the video of the 1990 whirlpool clean touch washer with that low f toned droning during full-speed agitation? Most whirlpool direct drives don't have that, but some do. Why is that? They do make that chugga chugga sound.

Just repaired my refurbished Estate 24" DD this afternoon. Good thing I was home. Noticed the washer doing a long spin spray rinse.

When I stopped the machine the water kept coming in even when I unplugged it.

I am not very mechanically inclined but I knew it had to be the water valve cold side was stuck open.

An hour drive away and a $37 part later and I got my machine back up and running.

Glory to God for giving me the courage and ability to tackle something I normally would not have.

Hey guys, Thanks. I went to Redmond's appliance service in New Brunswick. About an hour drive away. Couldn't find a repair place that would come out that day.

There are enough YouTube tutorials on these machines for me to follow or just some of the great advice on this site.I have an interest now in doing these jobs myself. A DD washer is certain a good machine for a novice to cut his teeth on.

Yeah. I quite like this 24" Estate. The simple straight vane is very adequate for the tub size and I can load the machine full to the tub ring (not overloaded of course) and get good rollover. No need for a corkscrew, but they are fun to use in these smaller machines.

I like how aggressive the 100 degree arc gets out tough dirt. Who knew it would trickle down to the maytag line eventually? It went on from 2007-2010 before the switchover to the vmw design on practically all models.

Look at the overall design of the Whirlpool "wig-wag" design vs. the "DD." Easier to assemble, less parts, Easier to repair, better initial quality. IIRC there was an insert that came with each Design 2000 washer letting people know about the new wash system and the fact they could reduce the agitation time.

The GE FF vs their Plastic Tub design was a major reduction in cost too. That clutch system, the filter flow plumbing... It was the start of then end of over-engineering.

On my current 24" Estate I only used the full 14 minutes once just recently. That was for a dirty full load of work clothes, but generally I use 10 minutes or even 6 in many cases. On the low water level the straight vane makes the water "boil".

GE copycat

I remember when I was at my babysitter's house with a whirlpool dd washer. I'd hear it running all day. Before I moved into a single family home in 1999, my mom's friend and coworker had a whirlpool washer which had a short/fast stroke. We had to stay there for a few hours while we were getting my house ready to move in. Later on when we'd start using the GE filter-flo, I'd sit there and listen to it running. Even before I heard it running, I walked over to check it out when we moved into the house. Little did I know that in 2 short years the transmission would dump oil all over the area where it was sitting. We had to get a complete new set. What I didn't realize was that we received the GE copycat to the whirlpool direct drive so you could imagine what I was thinking when I expected filter-flo and minibasket. The agitation is what sounded similar to the whirlpool direct drives.

GE FF Washer Dumping Oil

This happened from time to time but was an easy fix, it took less than 1/2 hour to install a replacement rebuilt GE transmission and there was certainly no reason to replace the dryer in any case.

 

I will never understand people, if you have something you like fix it.

The Raytheon 2 belt stationary motor design would have dominated. The DD design would have been rejected for more than several reasons and Whirlpool would have been copying Raytheon.  

 

But, as much as I don't approve of DDs their longevity has and is being proven. I remember Maytag did a competition where a DD Kenmore ran 24/7 side by side with a Maytag washer. The DD only needed two minor repairs, but kept going along side the Maytag. There are homes with DD washers that have lasted as long as Maytag center dials. 

 

For what it is, and considering its cost, the DD lasts for its money.

I noticed that the transition from BD to DD was gradual, and also kind of hush-hush, over about 5-6 years, and the lower priced models were first to get converted. Top of line like the Limited Edition were still BD as of 1986 when we looked at it. Was there any reason for this gradual change over? Maybe Whirlpool wanted to see if people would object? Did I read maybe here that WP stockpiled some BD machines toward the end of production in case consumers were not happy?

GE vs whirlpool

We had to get a new complete set so that we could have a dryer that could keep up. It was the same brand as the previous GE pair. The plastic GE and whirlpool sounded very similar when they agitated. I have used both units before and they did a good job. Now, whirlpool DD is taking the place of the GE filter-flo as far as durability is concerned.

I understand Whirlpool had to redesign their washer line. It was an outdated design and hard to work on. I've liked the DD design since our first Whirlpool DD in 1988 and think it's a great design. Would have been nice though if they could have made the DD a longer stroke agitation but it was a VERY reliable design overall. I'm pro DD design. Never had anything ripped up in one.

whirlpool dd

I miss the whirlpool direct drive washers. They could provide turnover on big loads with the extra roll agitator. I love the smells and sounds of it.
I've noticed the gear oil smell during operation which reminds me of my GE filter-flo. That's the only thing the 2 washers have in common is the gear oil and how it smells. One more. Both clean well. I believe the whirlpool/kenmore direct drives took the GE filter-flo's spot in durability.

What I found on Google:

So this design IS 1970's! Maybe not quite this design exactly, but they were just in the beginning stages of engineering what would ultimately become the DD. From 1979--however on Google, it actually says it was filed in 1978.

Surely it takes a few years to get engineering/design settled and patents registered.  That patent is in the Patent of the Day library.  Do you look at those?

Direct-drive was introduced sometime in 1981 via Kenmore, a few models in the line to test the market response, then all standard-capacity models segued to DD with 18lb super-capacity remaining belt-drive until the 27" direct-drives debuted and replaced them.

DADoES,

Do you know if there's a way to get to the POD library? I only know how to see the current one, but wasn't sure if there was a way to see the archives or not.
Anywhos, just found that and got real excited I guess...

The Picture Of The Day (POD) and Patent Of The Day (also POD) is updated every day. Only way to have a library of Patent Of The Day is to save them to some sort of digital album. Usually the Picture Of The Day along with Patent Of The day will repeat itself sometime within the next year or so.

Patent-of-the-Day .pdfs and Picture-of-the-Day photos can be saved by anyone as a personal library.  Heed Robert's request to not re-post Pictures-of-the-Day, they are to be viewed on AW only via the random daily rotation.

I've saved them for years.  Patents are saved in folders named by manufacturer (Misc for those not attributed to a specific manufacturer).  I append the "Filed" date in format of yyyy-mm-dd and a brief description to the file names so they sort in date order by file name.  Pat 4,174,622 for example is file name 1978-07-27 Direct-Drive Tub Suspension 4174622.pdf.
