Permanent Press Cooldown That Fills While Agitating

Chet, I've had to reflect back 36 years to remember the detail. But, it would begin spin/drain and when the pressure switch cut out, then water would begin spraying in and at some point not too soon afterward, spinning would stop and the water would continue filling until pressure switch water level was satisfied and cooled agitation would begin.
Sounds like a classic DD cool down.
The thing to remember is that GE timers tended to be continuous advance, so the timer would have to spend time pausing between each function to take into account the time it took for contacts to open/close in the correct sequence plus in addition that closing the motor drop off contacts, opening the motor drop on contacts, then opening the drop off contacts. That added time to the whole cycle, and if the PP cycle is on a very featured timer, there would have to be more drum space to assure all contacts have opened and closed correctly so that may explain the long agitation during the cool down period.

Edit: Never mind, DDs don't cool down that way. They pause after the pressure switch cuts out, then advance to fill, then agitate once satisfied.
I'm guessing they might have simply re-used the existing busing and wiring scheme from previous models instead of routing the motor through the pressure switch while in the full state. Basically the normal GE FF continuous spray rinse spin but shortened to something like 30 seconds. Then the timer switches contacts as identical to any other rinse, then advances to spin, then rinse, then spin.
Thats my best guess on how they might have done it.

KM cool-down sequence timeline
All dates are 'circa'.
1958 - 1st (timer) increment: alternate high-speed partial drain and fill; 2nd increment: pause (on selected models)
1964 - 1st increment: low-speed drain, simultaneous fill and low-speed agitation; 2nd increment: fill only, low-speed agitation when full; 3rd and 4th increments: repeat of 1st and 2nd respective increments
1974 - Aforementioned 1964 sequence eliminated the repeat
1976 - 1st increment: partial high-speed drain, pause; 2nd increment: fill, high-speed agitation when full (Concurrent with the introduction of the Dual-Action agitator)
If you notice in that Canadian KM, the timer moved when it started the agitation after the cool-down filling.

Cycle Descriptions
I found the information on when the modified cool-down process was introduced. It was 1967. See below....
I found the information on when the modified cool-down process was introduced. It was 1967. See below....
The original double cool down sequence of four 2-min increments on our 1976 WP Supreme 80:
1st increment = partial drain (to water level reset) and pause for the remainder of the 2 mins
2nd increment = refill, agitate two mins at low speed
3rd increment = partial drain (to water level reset) and pause for the remainder of the 2 mins
4th increment = refill, agitate two mins at low speed
Proceed to full drain, 1st spin, deep rinse, final spin.
The revised single cool down sequence on the new timer was partial drain with pause, refill and agitate (possibly 4 mins instead of 2 to use up the cam space), proceed to full drain, spin, rinse, etc.
This is the Super Wash-n-Wear cycle on a 1963 WP Imperial Mark XII. It has the Super Wash sequence of prewash, 2-mins soak, partial drain. Refill for the regular wash period is at 14:04. Speed shift to low for the last 4 mins of wash (at 22:16). Cool down sequence (begins at 26:16) of partial drains and refills, no agitation.
Yes, I have one. I'm not at home right now; I'll post it later this afternoon.

Kenmore Cooldown
In my opinion if the washer had a waterfall filter, and you were using the Normal cycle, You always got a blast of suds on the startup of rinse. Which always made for a cloudy rinse. But when using the Permanent Press cycle, it flushed it out, so you got an actual nice clear rinse. I always thought with Kenmores, with the neutral drain, and waterfall filters, were never great rinsers, unless you used PP Cycle. The automatic filters were the exception.

Wiring diagram/cycle chart
This is from model LSA9920 (1968). You can see the increments for Drain/Fill & then Fill/Agitate.
All WP & KM washers used this sequence from 1967 until about 1975/76 when it changed to reduce water consumption. At that time WP (& other manufacturers) must have realized the trending change in consumer behavior towards these fabrics, combined with the realization that the Dryer did most of the work getting out the wrinkles (as we've all said), and thus determined that reducing the water consumption would not affect perceived performance. The cycle became more of a "gimmick" selling feature (e.g. which manufacturer wanted to be the first to omit it entirely?).

Thank You!!!!!!!!!!!!!!!
Way cool. As always I love Whirlpool's simplicity and straight forward design. Letting the motor run until the pressure switch drops, starts filling while the timer advances to the next portion.

Another major difference in 60s-70s Kenmores and Whirlpool Wash 'n' Wear/Permanent Press cycles is their deep rinse agitation speeds. The former agitated on high speed, while the latter agitated on low.
I remember our 1970 Imperial stated in the owners manual
that during PP Cool down the machine would agitate/drain to keep the clothes moving so that creasing was minimized. That was the whole point of cooling down the wash water in stages.

rd video must have been hard on timer contacts, with the quick on/off cycle of the motor. Almost looks like spin is engaged, but I guess it is just with no water in the tub the agitator moving the clothes which moves the basket.

I still think this whole cycle was just a scam to try and make more cycles. It's only slightly different than running a gentle cycle on cold wash.
We people need THAT drama...

Did any WP's from between 1963 and 1979 ever drain and fill without pausing before resuming agitation? Also, was the draining in low speed during that era?
