the timing I believe is 60 seconds, and then shuts off.....this works on any cycle I learned once that selector is set and runs out of time...once spin is engaged, the filter flow resumes as normal...this is not to be confused with a Mini-Quick cycle....there will be two rinses and spin sprays...
the SS cycle for NonSS machines is just an ExtraCleaningCycle, Complete Normal cycle with two rinses and two spin sprays....
You can use the SScycle as a regular cycle as well for a full load, without turning off the filterflo, great for items like towels....
just an interesting setup of features and controls....
