Perm Press Cool Down

[supersurgilator]

When did Kenmore/Whirlpool switch from the partial drain, cool down to the spin spray? I have a Kenmore from late 1983 that still does the partial drain cool down, but wondered when they changed this. Also was Kenmore/Whirlpool the only manufacture to use the partial drain cool down?

Maytag Permenent Press cycle on fabric matics have a partial spin drain, then refill, then partial spin drain, then fill, rinse agaitate, spin and spray rinse.

Maytags pumps are mechanincal and need the tub to spin to empty. Some of the Whilpools had electric pumps that did not require the tub to spin in order to empty the water.

I wasn't aware Whirlpool or Kenmore ever switched to a spin spray only cooldown process. I thought it has always been a partial drain and refill with cold water process. But, then I haven't used Kenmore or Whirlpool washer newer than 10 years ever. My GE FF from 1978 did the partial drain with spin spray once. But within 2 yers GE went back to the spin spray only cooldown process. Maytag also did this sequence too, even my mom's 1995 Dependable Care did the sequence. I don't think the Frigidaire 1/18 did anytthing but a long spin spray on both PP & Knit Delicate. As far as I know, the SQ and Amana cousins only did spin sprays. The Norge products did spin spray too, but coupled with a slow spin (drain), the machine started spinning when there waere a few gallons of water left at the bottom just about the time the timer advanced into the spin spray rinses. I think I've covered all the major top loading brands.

Well I haven't used the perm press cycle on a newer whirlpool but assumed it was just a spin spray. My grandma's Maytag from 2000 only did a spin spray.

Mums 2004 Whirlpool would do a partial drain, refill, drain, spin, spray and spin, spin, Rinse.

The 1-18 GM's did do a partial spin drain, refill, short agitate on slow speed, full spin out with spray rinse, then deep rinse. It was only 1 partial drain.

It seems, pretty much, that the permanet press cycle was pretty much bullshit and a water waster.

Perhaps laundress could help us, but one was supposed to use hot on perm press then the cool down to prevent wrinkles at a slower tub speed and double rinse? Then the dryer on my Maytag has a perm press button which runs hotter than the regular cycle, with a longer cool down.

I am not sure most people make the distinction between Perm press and regular any more.

The Perm Press wash cycle could be helpful when line-drying. Otherwise, the dryer pretty much takes precedence over what might happen during the washing process. The local Whirlpool dealer always advised his customers not to bother with the Perm Press wash if tumble-drying.

Hot or warm wash temp relaxes the Perm Press-treated fabric to shed wrinkles, then the cool down "un"relaxes the fabric while floating loosely so as to not be crushed (wrinkled again) if spun warm or hot. Slow spin further guards against re-wrinkling.

Even if it has no appreciable effect, cool downs may still incorporated into the Perm Press or Casual/Wrinkle Free wash cycle on agitator toploaders in some fashion or other. Both of my F&Ps (1999 model and 2004 model) do so by running an extra rinse before the first spin -- full drain, cold refill, brief agitation.

As explained by documentation I've read on the 906 dryer, and by Tom Turbomatic, Maytag's theory on Perm Press drying was that perm press fabrics can't be overdried. After the dryness sensor triggered the load as "done," heating continued to a higher target temperature (165°F?) to insure wrinkles were "ironed out," then the cool down commenced. IIRC, 906 user instructions advised to use the Perm Press cycle when drying items such as jeans that have heavy seams.

IIRC, Lower end, Maytag fabricmatic washer instructions advised to use permanent press for items you wanted to "extra rinse".

When to use Perm Press

When would you use this cycle? For what type of fabrics? I tried it once on my whirlpool, and it isn't all that great for line drying, because the final spin cycle is on the slower speed.

I' m a permapress addicted

I run perma press to wash linen, polyester (both as a "fabric" and as "fleece") and easy care cottons such as Patagonia AC dress shirts.

Have to say I use a frontloader and the line (..and NO iron).
The difference is very remarkable @ 140°F or higher temps when washing linen shirts

New FL have partial drain-refill-some rev tumbles-part drain-refill- rev tumbles- drain- 2 or 3 spin bursts alternated with rev tumbles.

Old FL did no interim spins, several partial drains/refills (up to 5 mins) and wasted a lot of water. They had even the permapress boilwash for linen (dress shirts, tablecloths and sheets)

Front loaders can have various spinning patterns thanks to their design - it makes possible to have tumbles between spin bursts-. On permapress both intermediate and final spin have this typical pattern :
tumble-burst-rev tumble-burst- rev tumble-short spin-tumble-spin
This prevents wrinkling and allows even 1200 rpm : sharp fit 4 us line users

Do agree with DAdoES about the dryer "ironing effect" on polyester (not so much about linen). Had a crappy Candy combo that spun all wet & wrinkled, but when drying it "ironed" clothes (unless it was overloaded...)

Had a friend washed his nicer clothes in cold water on perm press cycle (belt-drive Kenmore). I thought, what a waste, but he insisted it was the right thing to do.

The new Kenmores and Whirlpools neutral drain the wash water until the water can not longer be seen in the basket. The basket spins a quarter to a half turn in one direction and then in the other. The electric pump turns off. The basket spins at extra slow (About 60 to 90 RPM which is the same speed they use for spraying and re-circulating the detergent at the start of the cycle). Once the basket gets up to speed, cold water sprays while spinning for less than a minute. The water shuts off, the basket comes to a stop, and the electric drain pump turns back on, and once the water is emptied the basket spins a quarter to a half turn in one direction and then in the other. The washer spins, rinses and spins as normal with a slow final spin.

Anyone have any videos of an agi Cabrio in action?

Hey Jeff! Howdy!

The quarter/half basket turns are part of the drain, to confirm the water is drained and the basket is settled from floating back onto the drive coupler. F&P does the same. F&P's "stir" speed during fill and recirculate is 25 RPM. I'd love to see a full agitator Cabrio cycle, note what differences there are compared to F&P.
