"A" Rated Spin Cycles

[chrisbsuk]

does anyone think that a 1200 RPM machine would ever get an "A" rating for spin performance?? i know its 1600 RPM and up that only seem to have this... would spinning say an extra 5 minutes at 1200 RPM be enough to increase the rating??

I wonder what rating a Hoover Aristocat 1300 would get!!

The bigger the drum the higher the G forces at any given speed, and G forces translate to extraction efficiency. So, a small 5kg washer spinning at 1200rpm will pull less G's than a 10 kg drum spinning at the same speed - so it is possible that on large drum washers that A spin ratings can be achieved at 1200rpm. That's why a lot of 1400 washers nowadays now also have A spin performance; because they have bigger drums so have more extraction force during the spin.

thankyou....

thanks for that Jon

Hi Chris

People have asked me if im worried about the whirlpool top loader spinning at such low speed (430 I think on slow speed and 630 for fast) but because the tub is so large I think its equivelent to approx 700/800rpm and 1000/1100rpm of a normal size front loader.When I had my admiral top loader I was more than happy with the water extraction from the spin cycle so ill probably be more than happy with the Whirlpool.

I think they have a "G" rating for spin though so it dosent look good for a potential purchaser of the machine.

Hi Mark, I have just sold my top loading kenmore washer dryer combo unit, and i agree with you that although it spun at about 600 rpm the clothes were actualy quite dry - it was rated as G for energy, G for cleaning and F for spinning - but i dont think this is a fair test as it doesnt have a 60*c cycle to test... make sense?
i have put a link to take you to the ebay page... hope it works

Pardon our interruption...

Hi Chris

Nice machines. I have always liked the seperates though as the space for you to leen in and get the washing under the dryer never looks big enough for me.I know I would always be banging my head! But then again I have never actually seen one in the flesh so cant really comment.

I agree that I dont think its fair giving the washers such a bad rating.Just because there isnt the usual 60* which they test machines on I cant see how it can have such bad ratings.I suppose one of them is because of the high water usage but you would have thought because there is no heater it would fair better!

Its a mr whirly , who cares what the rating is !!

 

[foraloysius]

Fair or not, these figures are based on research. They probably calculated in the energy that is needed to heat the water in an external water heater, which makes sense ofcourse.

Here's a link to a G-force calculator. Get the measure tape out and have some fun. Make sure you measure the radius of the drum and not the diameter. And it's in millimeters!

The radius of my Miele W715 is about 235mm, the max. spinspeed is 1400rpm, so G = 515 units.

My Miele spindryer measures 120mm, the spinspeed is 2800rpm. G = 1053 units.

not seen a 1000 spin hotpoint on sale for a while. Do they stil claim 1000rpm can achieve a B rating? That always got me why zanusis which imo spin better at 1000 but only got a C. I judge this by identical loads and their drying times in the same dryer. About 20 mins difference and the hotpoint spun for longer.

Quite beyond me that one actually. I had a post merloni Aquarius 1300, we were assured that the spin was fine and was working correctly, didnt explain why I could wring water out of towels after a 1300 spin if i tried hard enough. And that was supposed to be a B rating. The Zanussi Timeline which replaced it did a better job of spinning towels on the short 900 spin on the synthetics cycle! Again a B rated spin machine. But in my experience of hotpoint a B rating out of a 1000 spin!, if its anything like my hotpoint was then I think there is some bribing going on lol!

 

[lavamat_jon]

Actually if you look at Hotpoint's spin ratings, it seems they don't fluctuate between the machines... in the brochure all the Aquarius models have 54% remaining moisture in the load, whether they are 1400 or 1000 spin!

[chrisbsuk]

must be a miss print - there must be a diference between 1000 and 1400

 

[lavamat_jon]

I know - but it's a thing Hotpoint have done on the Aquarius range ever since the first WMA machines came out in 2000!

[chrisbsuk]

i dont trust them!!!

 

[sadose]

to be honest I've never really understood the logic by all hotpoints having grade B spin efficiency. The only thing i can think of is that the 1000 spin must prove more effective by being held at the same spin speed for along time as previously mentioned the 1300 spin WF430p I had was woeful.

Strange this actually, as both my aunts had hotpoints, the 9514 and the ???? forget the model number but it was a very early 95 series with a chrome door and a green mains light that never went off until you took out the plug. Anyway upshot is that the 9514 was an 800rpm machine and the ???? was a 1000rpm machine but there was always a marked difference (not just the imagination) between the 800 and 1000. The 800 spin machine managed to extract more water from heavy items much more effectively than the 1000rpm. Not got a clue why though...

1400 Spin Beko Machines are AAA Rated, apparently they ramp upto 1400 for a min or so slow down adn ramp back upto 1400 for 3 minutes or so, does spinning the load twice actually remove more water ??

Take Care

My neighbours Beko Washer that ive used does two final final spins lol, exactly the same as each other. there're rather lengthy spins which do give good results. But im still not convinced two spins that are the same will remove more water lol i just see it as more stress on the motor!

spins

As i've said on here b4 somewhere my Hoover Nextra 1600 spin machine had a very poor spin yet was an A rated machine spinning with a 7.5kg drum. The clothes could still be rung out if you really tried, compared with my Hoover 1200 new wave or my LG intellowasher 1200 which spun for 4 mins at full whack the clothes were much dryer and could not be rung out at all. So i pay little attention to these A ratings as they seem to be rather misleading and could do with a bit of investigating me thinks.
