Question to the experts.

Why did the japanese engineers used an oblong shape for the drum?
If it was only for the hydrodinamics during wash, it is quite understandable, not a big deal, affect the capacity minimally but improves the cleaning power.

The extraction in that washer is really intriguing. Kevin confirmed it's 900 RPM,just in case I'll run the tachometer to reconfirm this info but it extracts too much water for that diameter and RPM. I mean, maybe 15% more, it's a giant discrepancy. It is almost like this washer managed to break the fisics laws!

Different from all the theory we know about centrifugal forces, RPM and hole pattern, would the oblong drum cause that? What else could make it extract so much water? Am I missing something?

Other possibility is if that washer spins at 1100 to 1350 rpm (which i obviously doubt) then the result would be the same as predicted with the G-force formula.
 
Just because it's old and cute does not make it great.

More than 4 decades ago, the poor rinsing caused friends to have to visit the dermatologist to find the reason for the rash in their underwear regions. It was determined to be contact dermatitis from inadequate rinsing so everything had to go through additional rinses. I have no idea of their laundering habits, but be cautious of the rinsing and make sure that the last rinse water is not slippery from detergent still left in the fabrics. The machine has such a terrible tendency to suds lock that it did not spin between water changes so the rinsing is impaired. 

 

It would make a great companion to a GE combo to get some real water extraction before the drying.
 
What a cutty pie!

I thought the no spin between rinses was by design, rather than suds lock. Would Bill or Thomas clarify?
New in Box is such a delight; without this place, we'd never see them. I'd love to have that toy! Someday, maybe we'll get a huge trade-a-thon going.
 
Tom, the rinsing on that washer is not "wow, OMG, the best thing ever seen in my whole life", but it's also not bad. It is actually much better than many washer I've seen.

Lots of people say about this tendency to suds lock. I didn't see anything wrong with it until now. even using lots of detergent (i tend to overdose).

If i used only enough detergent and followed only the standard cycle, the rinse would be OK (not fantastic, but far from being poor)

Anyway, I'm a little paranoid about rinsing. If I see a single bubble on the drain water I always rinse again. I don't even consider going to the final rinse without spinning the load first and I never run a load rinsing less than 3 times before the final rinse with softener.

The extraction in that washer is amazing (for that size). I would say it's even better than many full size top load washers from those years. But anyway, even clothes spun at "Samtag" or the LG front load go to the spin dryer before going to the dryer. I spin up to the very last drop, to save as much gas and electricity as possible on the dryer.

Also, this washer is a little treasure. Of course I won't use it as frequently because i want to preserve it as new as possible for many years.

I don't understant that very well, but it seems that some versions don't spin between rinses, and other versions do (and have suds lock issues)

My unit doesn't spin between rinses, only the final spin.

i've done some tests exactly to try to cause a suds locks (lots of detergent, like 3 scoops of tide) and spun right after the wash. NO suds lock at all!

Actually I loved the pump layout very well made to push the air out of it as soon as the hose before it is full of water, different from nearly 100% of modern pump layouts that struggle with a tiny air bubble.
 
The agitation also doesn't disturb the water surface that much, so it doesn't create foam and the gentle swirling pops the bubbles. When you start the washer, the fill jet will create a world of suds, but then, during the wash the foam disappears, it's actually boring. (anyway, foam doesn't clean)

I can't imagine this washer causing suds lock if used following the cycles on the timer. Maybe if I put a whole box of detergent and force spin while it is still full of water.

Also, the gap between the drum and the bottom of the tub is huge (you start filling the washer and it takes forever to reach the drum), so there is more-than-enough space to spin without the water reaching the bottom of the drum, even with a slow pump.
 
Part 4

Of course this cycle was just for demonstration (Thanks Kevin for lending the test load)

I would never think about doing my laundry with only two rinses, no matter what washer, but the videos would be too long if I did the 5 or 6 rinses I usually do on whatever top load washer.

well, I am not going to try to convince anyone against their will, but it could not spin, even after the first rinse without sudlocking as the water was spun out of the fabrics and filled the area between the tubs with foam. It had a hard enough time doing it after the second deep rinse because the wash water had not been extracted from the load. The machine does not provide vigorous agitation like an agiator washer to flush water through the fabrics. That is why my friends got rashes. We found this rinsing situation in the shop, too, even with controlled sudsing detergent. Maybe with Rosalie's Zero Suds you could get away with a spin earlier in the cycle, but that detergent, with no suds, if left in clothes will give nasty rashes, too.

Enjoy your toy. I am happy for you. Zesser Gottenu.
 
Tom, That's interesting...

Is there any possibility they used two different designs for the tub?

I didn't take my washer apart (and I won't do it) but once I start filling, it takes several seconds for the water to reach the drum.

The drum even fills about 1 inch (before the bottom row of holes) because my water pressure is really high, but if i stop the washer, it will flow to the sump and the drum will drain completelly.

It means there is A LOT of space (and consequently this washer is far from being water efficient)

As I said, I did a test only to try to cause a suds lock (3 scoops of tide and an overload of towels) I wanted to intentionally cause THE king of the suds lock and nothing happened. It spun the water adn it never reached the bottom of the drum. It was spinning at full speed and for almost a minute there was water (and foam) coming out of the drain hose.

Anyway, Thanks for the advice, I always rinse much more than the regular cycle. I can even let any washer complete the original cycle, but then I always repeat several times until i see the drain water 100% clear, then i run an extra rinse with the fabric softener.
