Spray rinse
mark_wpduet, the 'High' setting on Normal cycle will perform a final spin of anywhere from 1100-1255 RPM for only about 1-2 minutes. Whereas the 'Extra High" setting adds anywhere from 8-14 minutes of spinning at that speed. IF you need something washed quickly, this would be sufficient, however a full load of laundry is not ideal. My Duet was programmed so that the spin setting purely changed the spin RPM, which I preferred. However, at least on my Kenmore, the spin RPM is highly variable. Last week I did a load of 4 pairs of jeans and 4 t-shirts and the machine decided to do the 1255 RPM spin. Though, if I have a large load of towels, washcloths, and bathmat, the machine usually will do a 1129 RPM spin. No ramping up for the last minute or anything. Spin performance is still great, but it's not at all what I was used to.
The interim spin with TurboWash is also too short and at too low of an RPM now. The older models would spin up to nearly 1000 RPM after the long spray, however, now they are lucky to spin to any more than 400 RPM and the interim spin is done. Plus, the drain pump stops as the machine ramps down, so there is still sudsy water in the sump that is used for the rinse. Not sure if they avoid the higher speed and longer duration to avoid sudslocks, or purely are doing it for time purposes. Since the water level in the rinse is significantly higher, I know they aren't doing it for efficiency. Though, I do believe the entire concept of TurboWash is efficiency driven on the Normal and Heavy Duty cycles. If an 8 pound load can be washed in 8-9 gallons of water, and the option can not be turned off, there is a specific reason why. CR would initially test TurboWash machines with the option turned OFF, as they do not run additional options or features for their testing cycles. Thats just my opinion on it though.
