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.
