I remember our laundromat overwhelmed with suds practically every time it was used, during the last year we lived in that house. The Maid believed as my mom did that more suds meant better cleaning. Watching it attempt a normal spin speed I'd see the foaming slurry drool and spit from between the boot and basket. Quite a few times, the overload protection would trip the timer, stopping the washer, till it cooled off. I wonder today how many machines met an early demise because of suds lock...
With this pic, I pour a small amount of Downy thru the vent hole just as the first spin begins, after the first spray rinse...it clears it immediately !
