Rinsing...

Phosphate based detergents rinse out far better than the zeolite based ones. This is why old high-sudsing Daz still has this formulation, because the clothes don't get properly agitated in the spinner drum of a twintub. If you were to use zeolite based detergents in a twintub, you would be likely to notice whitish residues in the clothes.

In a frontloader, the clothes are flopped and droppped and allow residues to be flushed out of the clothes quite readily.

Tumble Dryer

I heard that, if Dyson had released a matching dryer, it would have had a cyclone lint filter - similar to their vacuums.

Rinsing....

If you read which or most online reviews that cover rinsing, the most you will find them to say most modern machines rinse to an "Acceptable" standard. Not good, not great, not excellent.

I dont think 7 or 8kg of laundry tumbling in 14 litres or less of water per rinse is going to give excellent results. In reference to the "drop and flow" technique, this is far more effective when the clothes are sodden wet & fall into a deep amount of water. I dont believe this would be the case with a machine that uses 42litres.

Like its been covered the interm spins help alot with rinsing. but a decent amount of water is necessary. You can get away with 2 deep rinses and fast interm spins to produce a satisfactory rinse.

I've yet to hear someone say a modern machine rinses heaps better than anything from 1980.

Rinsing...

If the machine used a pumped system, the clothes would get a decent soaking.

Part of the problem will be the customer not reading the instructions properly, and overdosing on detergent.

I know of someone who put a liquitab into the powder drawer, then moaned about the residue not dissolving!

Rinsing

On the subject of rinsing, I have to say that, imho, all this jetsystem technology is more of a marketing gimmick than any aspect of the dyson washing machine.

I fail to see how a small jet of water can enable faster water penetration than the fact the clothes are about to drop into a tub of water at the bottom? It makes no sense, once the clothes are fully soaked, all the jetsystem is doing is recycling the water.

I too have an electrolux insight and a hotpoint ultima (currently looking for a dyson). The electrolux boasts 8KG however there is no way I would put 8KG in it.

There is nothing wrong with the washing, however the rinsing completly lets the machine down, the water levels are not high enough to extract detergent, and even by the 5th rinse (with spins inbetween), there is still often detergent left. How can this be economical !?

My hotpoint ultima (5KG) outside does 3 rinses, however the water level is great, the detergent is always fully rinsed regardless of how much it has been over dosed. As I see it the electricity used to turn the drum, and spin inbetween, for 5 rinses in the electrolux is what I would call uneconomical when it is being let down by the poor water level and could do it in 3 rinses if the water levels increased.

I am still looking for a contrarotor to come up where I live, will be looking forward to owning one

Rinsing...

I used to be rather skeptical about the while Jetsystem Technology, until we got our Zanussi ( ZWF1431S ). I find the Jetsystem to be far more effective when washing full loads as you have water in the bottom of the drum, and a Jet of water being powered into the load. Seems to do a much better job at soaking the load down compared to any washer I've owned. I'm rather suprised to hear that the Electrolux Insight isnt very good at rinsing, I thought it'd have decent water level rinses like mine. With most detergents I find 2-3 Rinses to be plenty as the second rinse usually looks like it does in the pic below, I Tend to use Super Rinse if I use a detergent thats rather sudsy

Just thought I'd have my input lol

Soaking the load...

My point, precisely; thank you for your observations. I find that my Zanussi too, rinses perfectly well.

I've come to the conclusion that poor rinsing must go hand-in-hand with overdosing of detergent.

Rinsing

Rolls_rapide, I do not agree. Without sufficient water then the detergent cannot be absorbed, it is that simple.

The electrolux insight is not very good at rinsing. (unless my machine is faulty, of course)

The water level is good for 2-4KG load, however as soon as you get a load larger than that, they start to soak up most of the water and you hardly have any water level at all.

Put it this way, you can see absolutely no water in the drum with a large load 4KG+ (which is shocking considering they claim it can take an 8KG load).

All very well about modern detergents, but I would rather there be no suds left at the end of my rinse cycles, thankyou.

As I said, my hotpoint ultima WMA64 rinses fine, even if it has been over dosed all I need to select is add rinse (4 rinses in total), and all the detergent will be gone, even with a full towel load.

I still do not see how the jetsystem can soak the clothes much better than normal because they are sitting in water at the bottom of the drum anyway, when the jetsystem stopped working on my insight I was washing for 2 weeks without it and there was no difference.

Samsungfl, the water level on your machine looks good, mine doesent even come up the glass when empty.......

Dyson in action???

Does anyone have any photos or better yet video of a Dyson machine in operation???

THANKS!!!!

What programme and options are you using on your machine?

Which detergent are you using, and what quantity?

Are you in a hard or soft water area?

Do you use a whole-house water softener?

Is your laundry lightly or heavily soiled?

Do you leave a 'hands width' of space at the top of the laundry, or do you pack it tightly?

Do you use fabric softener? Fabric softener residue in the clothes (and machine) from previous washes will help to suppress suds.

Do you use the "Quick / Time Save" option? Using this will cause the machine to skip important spin/rinse phases, with poorer rinse results.

I have the Zanussi IZ16S: 5kg machine with tilted drum and tub. The cycles I use tend to be Cottons @ 40, 50, 60, and occasionally 30 degrees C. No additional rinses selected; Time Save not selected.

Because of the tilted tub design on my machine, water is rarely visible. The lifter paddles also act as water scoops, in addition to the jetsystem; though the paddles aren't as efficient as they would be in a horizontal tub design.

When a typical COTTONS programme starts, it does the following:

Fills sump for 5 seconds and slow tumbles.

After about a minute, fills to a low level at the same time as activating jetsystem pump. Subsequent water absorption by towels, etc., allows additional topping up.

After 5mins, jetsystem cuts out, drum speed becomes quicker, and thrashes the laundry if the drum wall. Heater engages at this point. Pattern of randomised drum rotation follows: normal speed, with random speed surges (like removing your foot from the accelerator momentarily, when driving the car).

When temperature has been attained, jetsystem cuts in again; if temp drops, heater switches on, and jetsystem stops.

When washing is complete, it drains and does a low spin; the speed depending upon the amount of foam generated.

Three rinses follow, using jetsystem as the tub fills to a low level.

Rinse 1 & 2 incorporate distribution-type rotations, whereby laundry is flung to the drum wall. Interspersed with normal tumbling. These rinses also switch in a spin-burst phase of low speed spins. Tub drains. Intermediate spins follow, of a medium speed.

Rinse 3 is normal tumbing with conditioner.

Spin profile does a very short low speed spin for a matter of seconds, followed by tumbling back and forth. Distribution having been achieved, ramps up the speed in stages until it is sitting at about 900rpm. Speed increases again, until it is at about 1200rpm for several minutes. Speed increases further, to 1600rpm for the last couple of minutes. Finally, fluff tumbles for a minute.

No foam detected during final spin.

Rolls_rapide,
Your zanussi's wash pattern is identical to my AEG's on the normal 2hr cycle! I do love the distribution and spin rinses, though they could do with being slightly deeper. Tell me, when you press quickwash/timesaver, does the machine do a short wash with 2 fairly deep rinses?

Darren

 

[samsungfl]

Wow!

Very intresting to hear that Zanussi also incorparated the Spin - Rinse Technology into their machines My 06' Zanussi dosnt do the spin rinsing or distribute filling rinses, though if I use Extra Quick it does a short wash, and two deep rinses like Darren mentioned

Just to compare : I tend to use the Extra Quick cottons cycles at 30,40,50,60 and 95*c When using a Cottons Wash (short cycle) it does the following:

Runs the pump for about 20 seconds

Begins to fill through the pre wash compartment for about 10seconds, then flushes down the Main Wash Compartment

Water begins to spread across the door rubber, then the Jetsystem is Activated

Starts to tumble at Cottons Wash speed and adds extra water if needed, then begins to heat

Once heated to the desired temp the pauses in between the tumbles shorten to about 1-2 seconds in between, rather than 5 or 6 as it does whilst heating

about 15 mins later, the cooldown portion starts.

Then, the wash water is drained and the machine does a few tumbles back and forth, then distributes.

1st spin is a burst up to 500, then it distributes again and starts of at 500rpm and speeds up to 900

Rinse one begins and fills to high level.

Rinse spin begins and reaches 1000rpm

Final rinse begins ( High Level )

Final spin profile : 500 rpm burst, redistributes and ramps up to 500 and increases quite quickly due to it being a short cycle. Stays at 1400 for about 2-3mins and slows, then instantly unlocks without an AntiCrease again due to Extra Quick Being selected lol

Just thought i'd compare the two, see how Zanussi's have changed over the past few years LOL

Hi Darren...

The quick/Time Save cuts the 2hr 6mins 40degree C wash, down to 1hr 3mins. This seems to give a half-hour wash, followed by two rinses; in-rinse spin-bursts appear to be omitted from the programme.

To tell you the truth, I've never noticed if the two rinses are deeper than normal. I'll try it shortly, as I've another small load to do.

When I bought the machine in the Spring of 2001, the brochures stated that it used 49 litres of water. I was pleasantly surprised to find that my machine was a later variant, that used 42 litres.

I think that it does a very good job, and I like the way the graphics, labels, etc, are under a plastic cover, preventing them from being rubbed off.

 

[rolls_rapide]

Richard...

Not at all - feel free to comment.

I'm quite interested in the wash/rinse/spin profiles of different makes of machine. (The Hoover New Wave was quite a revelation, compared to the fixed cycles of the previous Hoover Ecologics, and Hoover Electronic Deluxes, etc).

I think that if certain manufacturers took greater care in designing their machines' spin profiling, it would prevent them leaping about the floor. And the same goes for rinsing performance and wash performance.

 

[rolls_rapide]

Darren & Richard

The 40degree Cottons Quick cycle has just gone into the first rinse. Water level is no higher than normal length programme.

Second rinse coming up...

Second rinse is again, no higher than normal.

(Delicates and Woollens cycles fill substantially higher).

 

[kirri]

My ex next door neighbour had the cro1 and was very happy with it.It came with a 2 year guarantee and about a month after broke! She, of course hadn't extended the guarantee and when the Dyson engineer came, he found the machine was beyond repair.
I don't know if it was that she was heavily pregnant that he took pity on her, but he phoned the office up and within 3 days she had a brand new machine F.O.C.!! How's that for customer service!!!

Hi rolls rapide

I always use the normal cottons cycle on my machine, normally with extra rinse selected, occasionally I do use quick, but the water level is the same if quick is selected. I do live in a soft water area, however I alter the detergent as required. I only do very small washes, because I never have enough laundry to fill the drum.

The three rinses use low agitation on my insight, it tumbles the clothes with long intervals, no distribution-type speeds.

The last rinse fills up a small amount, tumbles once or twice, then fills up to what it should be.

The water level is still very low... as I said not even up the door with nothing in so as soon as towels go in then there is hardly any water in the drum..

Speaking of the foam sensor my machine apparantly has, I have never seen any evidence to suggest it works, perhaps my machine may be faulty.?

If you could tell me how the foam sensor influences the wash, I may be able to test it

 

[jwilson00]

foam sensor

i dont know bout the insight, but when i had my bosch which had a foam sensor, it only kicked in on the first spin after the wash cycle and only if it got a suds lock.
If this happened the machine would stop the spin, add a rinse except there wouldn't be any intern spins inbetween the rinses and after all that you would probably need to run another rinse cycle cause there would still be a load of detergent left.
unfortunatley the only time there was really a lot of foam was after the first rinse cycle, it would kick in the foam sensor but the machine would not add a extra rinse but instead cut out the rest of the spin cycles, oh and you'd also get a reduced final spin. I found it to be a total waste of time. i dont know however how the logixx performed with the lazor sensors that were supposed to check how cloudy the water is during rinses.

 

[samsungfl]

Electrolux and Foam Sensors....

I've noticed on my Zanussi that if it overfoams, it seems to alter the Jetsystem and keep it on for longer to try and supress the suds, maybe that's there type of foam sensor i'm not too sure LOL! Also if there is a Sudslock during the spin after wash it'll spin for a bit, slowdown and attempt to drain some of the suds out then go again.

Hope this helps

Richard

 

[rolls_rapide]

Foam Suppression

The abundance of foam clogs the pressure vessel, preventing the pressure switch from resetting, thus resulting in a spin that may be reduced in speed; or an interrupted spin, interspersed with tumbling whilst attempting to pump out the excess suds. If no headway can be gained, the machine goes into the next rinse.

Rinse sensors are different from foam sensing. A rinse sensor uses an led light source to shine through the water, measuring the amount of light reflected and refracted (ie; not landing on the normal receiving diode). The machine can add rinses until the rinse water is clear; so a small load might be able to get away with two rinses, but heavily soiled dungarees may require all three rinses, plus extra ones.
