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.

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.

Full cycle

Part 3 

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.

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.

I totally agree...

Ah, those Japanese engineers..... they don't have brains, they have supercomputers in their heads.

That washer is surprising even today.
