Hey Martin---
Martin----It's the agitator that indexes, not the tub. I watch that black tape, it goes clockwise 183 deg, back only 182, slowly creeping around the tub, very slowly. no worries. But not 210.
I have great water pressure, it seems between Large and Medium is right for a full load that starts with only a small amount of overflow. That's gotta be the easiest way to learn and adjust to a solid tub/time fill. And while the timer feels exact and solid, like Norge or 1-18 instead of Maytag, there are no detents for Large-Med-Small fill. I'll learn, and yes, I watch it all anyhows.
Malcolm---Very kind of you to offer a chrome cap--check your email--Thanks
This is a DA3780, tons of parts places list it and have over 20 diagrams---my Ephemera download is a 1975 SQ Line, does NOT list this DA3780, shows various stainless tub and porcelain, time versus pressure fill, one and 2 speed, etc. And the catalog explains each step of a cycle. This model seems to have the best of both worlds cycle-wise. For the deep rinse, there's no choice of fill, the agitation starts at about 85% full, and water continues for another minute. So without any spray rinse on Normal cycle, you nevertheless get agi-overflow rinse in wash, and again at both the start and finish of the deep rinse. So far, a big load of towels in high-sudsing Gain came out clean rinsed in one cycle. Most other machines, I give towels a second rinse and fab soft then. Also, the extraction in this model is great, that helps heavy towels better than a Kenmore at 550 rpms.
Fabric softening----I've seen videos of SQ with an agitator moiunted FS dispenser, but I think it's a waste for this model. With the overflow start of rinse, lots owuld go right overboard quick. I add a bit duing rinse agi once the water has stopped, cuz I like the smell and feel for towels, Other than that, I think I will treat this as a non Fab Sof machine.
Sweztoy-----you mentioned this is a "pre-brake" model. I'm new to SQ, but shutting it off in spin brakes in under 10 seconds, something is doing that. It ain't like a Norge with the slow slow slow end of cycle spindown. In another week, I'll be getting inside this for some lube and paint and de-rust, and I'll take pics. With my limited--very--knowledge of SQ solid tubs, and not knowing the exact year, etc, all I know is it is time fill, one speed, BOL options and small tub but well built.
The entire 6 models in 1975 had the exact same 2 cycle timer, with differences only for time versus pressure fills.
John L---no bleached white loads yet, I'll let you know. But seeing everything else, and those thick towels come so clear and clean, I bet one normal cycle will do the trick.. If I add one dose of FS after the initial rinse overflow, my guess is all bleach stink will be gone and undies will be white and smell fresh. I am 45 years too old to use the word undies.
MickyD----suds saving---There's no way in hell I can Rube Goldberg up a way to return suds, but plugging the sink to suck them into a different washer is fine. This model is small, some overflow comes right at the start of agitation, and in Normal cycle it uses WASH TEMP for the wash overflow. Between the small tub and the overflow and the spinout, it fills my 21 gallon washtubs just like the Kenmore and the GE(my factory suds FF saves suds just until the spray starts, not the entire pumpout) . So the saved suds will end up diluted noticeably, but still hot as hell, I can just add more soap in the next machine. Yes, I have to switch the hose to the unplugged sink for the rest of the cycle, but I am used to that with various Mark-rigged sudsaver models, no problem. And to save some water in the water heater, I can choose to switch to cold after the wash fill. Then the wash overflow is cold, giving me warm suds for next load if I don't want all hot.
Enough for now---thanks for all your advice----Solid Tub washing is new and fun---
