Leaving aside issues from creasing hot or very warm laundry, only reason can think of for slow spin speed between wash and first rinse, and or multiple rinses is to cut down on water usage.
More water extracted via spinning means more will be needed/absorbed in subsequent rinses. OTOH if leave things say 60% wet, then they won't absorb as much fresh water from rinse cycles. To be fair there always has been a debate about extracting wash between rinse cycles, at least for commercial laundries. On one side there are those who feel extracting after wash or first few rinses (if at all) pulls dirty water through laundry. This is a holdover from days when washers did just that; washed. Laundry was moved over to separate extractors after entire wash/rinsing cycles were completed to spin dry. Others feel that all laundry (at least normal/cottons/linens) should be extracted between wash and all rinse cycles. This lessens amount of rinsing required because dirty water, muck, detergent reside, etc.. are extracted out of wash via spinning. Thus each successive rinse should have cleaner water. With a top loader am dubious as to results of one rinse after a slow (and short) spin cycle. As you say plenty of dirt and whatever will still be in wash and or even caught between the tubs. But since all the government seems to care about nowadays is energy/water use, there you are. |

simply put...balancing!
short burst, pulsed, quick spins eliminate the extra time to make sure the load is perfectly balanced... there are a few machines that spend an extended amount of time distributing the load for the final spin, just to find that sweet spot...… not to mention if it can't, what sequences it must go through to get there, and try and try again.... imagine if it had to do that for every spin.....you think it takes a long time to run a cycle now! interesting how some machines, distribute the first time and take off....while others play around, which seems to take forever, if even getting to full final spin at all... |

My agitator F&Ps: spin after wash has one spray at 300 RPM, increase to 670 RPM, reduce to 300 for more sprays, 670 RPM, 300 for more sprays, 670 again, then proceed into the rinse fill. The number of sprays may change depending on load size (selected water level). Final spin is choice of 300, 670, or 1,010. Saturation sprays are at 25 RPM followed by 670 RPM extracts when the eco Shower Rinse option is selected. AquaSmart does (saturation) sprays at 25 RPM followed by extracts at 670, same whether or not the Fabric Softener (deep rinse) option is selected. The comforter/bulky-items cycle options on AquaSmart and Intuitive Eco run two deep rinses with no spin between. The machines pause and beep for attention before the final spin, advising the user to push the item down before pressing Start to continue. This is to avoid possible damage to a bulky/overstuffed comforter and such items that may have retained air and/or floated upward and would rub against the tub cover during spin. Perm Press/Creasables and Handwash on the agitator models have two deep rinses with no spin before the first to function as a cool down. |
