Well, if too much detergent was used in a load of laundry, the suds won't drain out and build up in the outer tub. And believe it or not it can drag down the inner tub during the spin cycle not allowing it to reach full spin speed. I've seen it happen many times, Whirlpools and Kenmore were notorious for it. I didn't get how something as delicate as bubbles can do that, but if you get enough of them in there, it happens. It's like when you drain a sink with sudsy dish soap and it takes a while to get all the suds down the drain. They don't pop as easy as you think.

Thanks, strongenough for responding. I understand what it is. What I'm curious about is the chemical properties of the soap bubbles that makes it happen. |

But my older Miele does a series of graduated spins before the main event to amoung other things, get much of the water and froth out to prevent suds locking.
Mind you like many front and top loaders then and now the machine also has a built in motor/pump protection system that slows down spinning if too much froth/water is being pushed out for the machine to handle at once. Personally have always felt this is where commercial washers with "dump" valves outshine domestic machines. You've not lived until you've seen a 50lb SQ laundromat front loader with a full load of say terry cloth bath linen go into a spin when high suds are present. |

Oh Launderess, I've watched a few commercial machines spin and it's a major experience in respect.
"Profile" spin is simply a programmed acceleration. Earlier machines had it too, via clutch slippage (e.g. Whirlpool) or belt slippage (e.g. Maytag) or more elegant hydraulic coupling (I'm not knowledgeable enough to quote examples). Machines today do it electronically by gradually ramping the motor speed from tumble to distribute to spin. |

In the UK it is when a spin cycle is broken into programmed segments and NOT continuous.....it was a feature that started in the 80`s with Creda (Rythmn Spin) and marketed by Hotpoint (Profile spin), later adopted by most other manufacturers, saying that Asko and V-Zug have a continuous gradual spin over 9 mins ramping up slowly but powerfully!!
Example of Profile Spin: (By no means the definitive) Distribution - pinning the clothes against the drum pumping out the water First spin - up to around 600rpm for 30 - 60 secs then stop, pumping out water Tumbling and loosening clothes , pumping Re-Distribution - again pinning clothes evenly 2nd spin - can be higher speed, more water extracted, continuous or breaks in pump out Tumbling and loosening clothes 3rd spin gardually building up to fastest speed selected So the biggest ammounts of water are taken out early on at low revs allowing the breaks which help the pump clear the backlog of water, as these days the tolerences between the tubs are so narrow and most machines have pumps that are average.. Also allows for re-distribution of clothing allowing even balance around the drum so less OOB and creasing - saying that with all the will in the world it can tend to be the random laws of nature as to whether one spin will be super smooth or another be a bone shaker!!!

Kool, interesting read guys. I've actually leant summit here by the workings of old and new machines. Mike, "Profile Spin" does that apply to the Bosch V series too, as these line of machine's did up to Nine intervals, so I'm guessing there was hardly no water to pump out by the end of the 9th interval... Do you have any idea to why they went on for that long, if I recall, it would go on for at least 20mins at a time?
There have been machines that has equally coped with sud locks, for example the Indesit L5, when it just went straight into its spin phase, with soapy water and the risk of suds lock was higher. Badgerdx you do come up with interesting topics, so thumbs up :) Hass. |

Yes Hass, the Bosch Siemens "Interval Spin" was the same thing, remove the bulk of the water at low revs whilst tumbling to reduce creasing and to get a good even balance around the drum....those machines where much quieter than say Hotpoints, and yes up to nine intervals!!!
Interestingly its not promoted as much as it was years ago when new, I suppose its part of the programme cycle we have gotten used to!! |

Greg, what do the Chinese characters say? Are they a prayer against oversudsing, placed there after you discovered the machine creaming the laundry room? Or, is that the machine's name in Chinese or maybe that universal Chinese term for trouble, Sum Ting Wong? |
