WCDAFN had the 6 fabric programs like the WIN Imperial, but without some of its features like the 1010 rpm spin and the metered infinite water level. It enabled settings for normal speed wash and slow spin for wash & wear/perma-pressed fabrics.
The WCDATN had 4 wash/rinse temp settings, timed fill and the strangest speed combinations: N/N, S/S and for perma-press, slow agitation and a fast spin, but not the 1010 rpm spin. You could not get normal agitation with a slow spin and I don't know what kind of perma-press fabrics needed slow agitation, which coupled with the space capsule agitator, did not produce a whole lot of wash action. So you only had one setting which gave normal agitation speed and, if you had a dryer, was probably OK for all but the most delicate perma-press items.
Because both of these machines had timed fill, a small load setting speeded up the timer so that there was less of everything: filling, agitation and spinning. It did mean though, that the rinse fill valve was open all during the agitation period of the rinse for true overflow rinsing. This was possible because the pump was operating during agitatioin as well as during spin. With the metered fill Imperial & Custon Imperial machines, the pump could not operate during agitation because it would empty the metering chamber which signaled the water level pressure switch. Because the pump could not operate during agitation, the overflow rinse period of the cycle was limited to two timer increments. Otherwise there would be too much water in the outer tub when the washer sent into spin-drain and the tub would drag on the high water--not good.
Finally a word about Frigidaire versus Maytag. Frigidaire FINALLY bit the bullet and designed a whole new machine to have a large capacity tub and had a very successful washer. It is a shame that the auto industry's slowdown as a result of the energy crises of the 70s caused GM to throw the appliances overboard, but at least their reputation was not in the toilet like Maytag's was before its closing due to failure to redesign their machine and the bringing in of outdated, inferior products to round out their appliance line. To the end of the General Motors ownership of Frigidaire, it was all Frigidaire, except for the Amana microwaves. For that, they can be forgiven because the Amanas were quality goods.
