Fisher Dishwasher Does Rinse Aid Only Work In The Rinse Cycle Of The Dishwasher?

Does rinse aid only work in the rinse cycle of the dishwasher? - fisher dishwasher

I never used the function of flushing in my dishwasher (Fisher & Paykel) and I noticed that the rinse aid works, never! I've always through that was used at any time during the laundry? I shows a rule that for a normal load of eco-mode. Typically, wash by hand.
