I haven't experienced a suds-lock in ages, even in the 51 Kenmore (with surgilator) but this machine doesn't have a recirculating filter of any kind. When I was using the 63 Kenmore washer (with self-cleaning glass bead filter) it locked up constantly. I wondered after comparing the two machines if it had something to do with the aeration of the detergent & water through the wash cycle as it was constantly pumped through the filter. The wash water seems to be much more "foamy" than without a filter, as if a lot of air is being whipped into the mix. Of course the roto-swirl agitator is also sucking air into the wash-water as well which might give it more fuel for foam...
I used to have suds problems with the large capacity Speed Queens I've had, part of the problem there may have been the size of the outer tub and the spin-tub whipping up more suds and slowing the spin. As of yet, I've never suds-locked a unimatic or the other solid tub machines I have, I guess I haven't tried hard enough!
