For some time the main bearing in my Dyson has been noisy, have had it apart for ages and finally gotten around to tackling removing the bearing. Certainly not the easiest task! Finally the old bearing is out and I thought I would share some pics.

What the full purple one? I'd quite like the silver one But this was a bargain. This one is a standard CR01, but I found a Memory key panel on ebay and fitted that. The switches that are on the memory are on the standard console board, just hidden. =)

So thats what the inside parts of the dyson look like! I have a CR01 machine, but it is our second and has been reconstructed by ourselves. They are very noisy machines and I have never liked them. Can't wait to get a better branded machine, it doesn't take a long number of years or months for the parts to be replaced on these machines!!

Post# 604830 , Reply# 13 6/19/2012 at 17:17 (336 days old) by ANDYVIVO (Essex)
Certainly a much nosier machine in contra-rotation mode, and a unique sound. I think they are hideous to look at, although look a bit more refined in pure white, and the silver versions. I do like the approach that they could do something totally different to what had been done before. Although it may have been done on the sloping front keymatic, just not sure if the pulsator turned opposite to the drum or the drum stayed stationary?

*Keymatic* Hi Andy , yes the Keymatic pulsator turned the opposite way to the drum, quite a drama splash action when both get going , hence only a 4 minute wash from correct temperature when on cottons, ie pulsator & drum both turning!!! CLICK HERE TO GO TO chestermikeuk's LINK

*Contra Rotator* Wow beefed up bearing for sure, can you take some pics of the gearbox drive unit, a;ways perplexed me as to how the drum system would work...you gonna keep this one??

Post# 604848 , Reply# 16 6/19/2012 at 18:29 (336 days old) by andyvivo (Essex)
*Keymatic* I always wondered about the wash action on the sloping fronts, I have seen your videos online and I bet it weighs a tonne! Is their any vids without a load to see? Yes the bearin had to the biggest I have seen in a domestic washer, 90x50x36mm. The replacement I have sourced is 34mm deep, so will find a 1 or 2 mm washer with a 50mm bore to make sure it doesn't inhibit the contra action. Not so happy with the bearing seal that I have sourced, it will be a gamble I guess. It is 1mm less in bore but does fit nicely on the seal collar. Just the front lip is not as proud as the original, although the replacement is double lipped like the original. I will keep it my small collection. It has been a challenge that's for sure =) Will post some more pics as progress is made. Waiting for a 6904zz bearing to replace the rear inner bearing. A little noisy and for the sake of whilst all apart would seem pointless to ignore. The set up is actually very simple, just a few planet gears with a motorised ramp to move the gears into position for contra rotate mode. Nb must work out how to reduce the size of the images i'm posting!

*Contra* No need to reduce the size of images , they are fine, give sperb detail!!, whats the yellow thingy with wire on top of the drum??

Post# 604909 , Reply# 18 6/20/2012 at 02:22 (336 days old) by ANDYVIVO (Essex)
*The yellow thingy* these are to do with the OOB detection, they are piezo accelerometers, and are used at the 800 and 1100 rpm part of the spin phase.

*The drive componants* The rear pulley, primarily connects to the main drum assy, the toothed part connects to.........

Post# 605066 , Reply# 20 6/20/2012 at 15:44 (335 days old) by ANDYVIVO (Essex)
*the planet hub* this is sprung, a motorised ramp pushes against the spokes to initiate contrarotation. The hub is opened for the gears to engage.

*The ramp ring* has two halves, the black ring is the operating ring for opening the planet hub, it locates with the slots in the outer drum.

So that is all on this one until reassembly, will take some more pics as this happens to better illustrate how it all comes together =)

Post# 607178 , Reply# 25 6/29/2012 at 18:40 (326 days old) by andyvivo (Essex)
*Update* So finally the drum is reassembled and all drum & pulley bearings changed, few teething troubles at first though. The main drum was very tight, although as halves for contrarotate are free, so that was an improvement. The main drum has freed up since spinning. I am disappointed that there is a bit of a chattering noise from the main bearing, considering it was pressed in. Can only hope that it will quieten given a few hot washes. And that the main bearing seal does the job lol. Will have to order the gearbox motor, it's on it's way out as it keeps getting stuck and slows. I have taken some pics of the ramp, gearbox and pulley system coming together. Will load these up soon.

Well done! I was amazed everytime the dyson engineer came to fix the washing machine, the machine surely was something different! Did you know by pressing the soil type button in the mode you had it in it will go to the next step in the program sequence. 24 stands for final spin, 25 for slowing down, 26 for anti crease tumble etc. We do miss the dyson for one reason, we can't wash our king size duvets at home anymore as the LG only has a 69litre drum so we have to go to the launderette and the machines aren't very good (Ipso with the clock dial). It was a good machine, excellent washing and very fast too. I want to ask what does Hz stand for on the display in diagnostic mode? When it was spinning it would hit 1750Hz, 64Hz (ish) on normal tumbling and 400Hz on contraroration. Happy washing :)

Post# 607614 , Reply# 37 7/2/2012 at 10:32 (324 days old) by andyvivo (Essex)
Can's say I have seen anything re the Hertz on the display, can only think it may be a later or earlier software version than what machine uses (v106 I think). I would think it would be representitive of the RPM the motors are working at? I have nothing in my service manuals that mention this, so a new one on me =) I'm always using the soil type button in diagnostics, takes too long for some parts in the cycle when just checking operation. Deffo useful for the duvet wash (main reason I wanted one) and it was a good job that it was fixed this weekend, one of the cats decided to chunder on the bed.... ewww! The drum is perfect for this. The machine was a bargain, an eBay find for �35.00 with F11, the bridge rectifier had failed so that was an easy fix. It started to get louder as the months went by, and it was starting to struggle in contrarotate. I kept putting it off for the amount of time I knew it was going to take, and not being my daily driver wasn't in a rush. However I am pleased as punch that it's running again, and relativly as quiet as it was. The bearing noise is starting to quieten down. Just need to get the gearbox motor replaced and the rear wheels and the beast can have a full bill of clean health lol. I would estimate by the time I have completed everything it will have cost about �135 in various parts (not just for the drum bearings but other bit's and bobs) but I think well worth it.

Hello Andy you must be pleased as punch to have won over one these possible nightmare machines, I am pleased for you and the machine. You will be one of the few people in England i would think with a fully working one, whenever they came into work it was always the gear box that had gone for the umpteenth time. I used to be tempted at times to take one home and have a fiddle, but i backed out Well Done Gary

Post# 607635 , Reply# 39 7/2/2012 at 11:30 (324 days old) by dyson2drums (United Kingdom)
I always thought it'd be the speed the machine is running at, if that is the case then the final spin is shown as 1750Hz! The only way I could get all that to display during the wash was to put it into diagnostic mode by pressing soil type and temperature button simultaneously upon pressing the on/off button and then starting a wash without switching it off. It displayed the temperature in degrees, Hz(most likely the rpm) and water level with (mm) as some sort of measurement from what I remember. The link below shows what is displayed on the display, I took this video over 4 years ago. CLICK HERE TO GO TO dyson2drums's LINK

Hi Gary, I think you would be quite right as there are probably quite a few failing because of the contrarotate not working, or main bearing on it's way out. Had these machines been released a few years later then the drum parts issue would probably wouldn't exist because of Chinese sourced parts. I think a lot of the problem would be the liquid detergent / fabric softner build up on the spiders. Causing rotting. There were a few locating pegs for the smaller inner shaft that were gone because of this decay. All I can say is get one cheap and have a play, it is worth it just to have a look at what goes on. D2D, i'm guessing that your CR02 had later software than mine as I don't get that kind of read out on diagnostics. Have to say they were a bit late in doing this info as my Zanussi displays that kind of information and that was built in 2001. Would have though Dyson would have nailed that. It would have been good if they had tried doing a more conventional style to capture more sales, as it was a bit of a marmite.

Post# 607697 , Reply# 41 7/2/2012 at 16:39 (323 days old) by dyson2drums (United Kingdom)
Well it was initially a CR01 upgraded to a CR02 under warranty. It was a marmite but that didn't stop us going for it lol. What machine do you have as your daily driver?

Post# 607702 , Reply# 42 7/2/2012 at 16:45 (323 days old) by andyvivo (Essex)
I have a zanussi IZ16S, and it's still as good as new. Only need the jetsytem pump needed so far. When you say upgraded, do you mean your CR01 was exchanged with a CR02, or did it have a cosmetic overhaul? (which if mine came into the house it would have to be all silver or all white lol)

I always liked the IZ washing machines :) Well it was the CR01 flowcheck in full white but the software was upgraded a few times. I wish ours was the silver CR02 allergy model, that looked stunning but the white one was okay. It surely stood out and was always commented on when we had visitors.

Post# 607717 , Reply# 45 7/2/2012 at 17:36 (323 days old) by andyvivo (Essex)
It is deffo a good daily driver, and easy to use. That was an important thing for my mum when I bought one for her to, I put her off with digital washers with a microtronic that took 3 hours on mixed load. Both are the heavy silver (not the IZ161 silver) but I liked that colour too. But by then I had the matching fridge freeze and dishwasher so no going back. Glad I didn't choose white as quite a few I have seen have the awful yellow ageing effect. What killed your dyson off?

Post# 607729 , Reply# 46 7/2/2012 at 17:58 (323 days old) by dyson2drums (United Kingdom)
It definitely was a really good daily driver. It did a lot of washing and was easy to use and the quick washing times were a bonus. However it had a few problems. We had it repaired out of warranty when the motors, interlock, planet carrier assembly were replaced and the drums were locked. After that 1 years cover expired from the repair it was causing problems by getting stuck on programs, it was very loud on spins so we decided to opt for a new washing machine. We needed something big and preferably graphite or silver so got the LG F1479FDS5 which we're very happy with :)

Well lets just say the start up tune and end tune plus the lights always intrigue visitors or family especially kids as they can't keep their hands off. We've had the machine switched off half way into a wash by a child as the power button isn't included in the child lock which i'd say is a design fault as it is the case with the LG at grans.

Post# 607736 , Reply# 49 7/2/2012 at 18:19 (323 days old) by andyvivo (Essex)
Yes that is daft, hopefully this will get revised on future machines. Does yours have steam cycle?

Post# 607849 , Reply# 50 7/3/2012 at 04:03 (323 days old) by dyson2drums (United Kingdom)
Yes its the model with steam wash, it does help on tough stains :) Doubt it as the child lock problem has been around for atleast 7 years or so.

*Contra* Great pics there Andy, such a complicated machine, similar to the Hoover keymatic using the hollow shaft to in the Hoover case driving the pulsator in Dysons case driving the contrarotator!! I often wondered if they had also offered a "Stripped back" version sleek & sophisticated with subtle colour, would they have sold more!! Most kitchen I`ve seen them in look like they are sat in the middle of the room given how much they stuck out from under worktops in small kitchens etc!!

It really is a pity that there wasn't an alternative option for a more discreet model, such as a toned down CR03. I personally wouldn't want it as my daily driver as it's does not ooze in the styling department. Bit like a Shrek of the laundry world lol. Although it would probably jut out less than my IZ, it doesn't have a time to go counter, which is a shame. And it's very heavy, so that also puts me off bringing it into the utility room. Intrestingly in my online trawl last night, I found a mention that a new Dyson model could be on the horizon? how true I don't know. There was no wine consumed last night, so I think my memory is not impaired on this one =D. Will post a link when I find it.

*69l is big enough for even a King size duvet* I just read a message from someone saying there 69l drum will not fit a duvet, and they miss the Dyson 74l drum for it. Can I just add the LG Steam has dedicated Duvet cycles (although not actually hot enough to kill the bed bug, but still at least they tried), and 69l is big enough for even King size duvets. I have washed a double Duvet in my 5KG 50l drum Hotpoint, and its been fine, with good results.

Post# 608028 , Reply# 58 7/3/2012 at 16:49 (322 days old) by dyson2drums (United Kingdom)
Hey glenfieldmathk1 I have tried putting the king size duvet into the washing machine but it just won't fit, a third or quarter of the duvet will stick out which means I can't even shut the door. I don't know what tog it is but its a thick duvet. I've fitted double duvets and they were washed very well with steam wash being selected. As far as i'm aware my old dyson had a 78l drum which is what it says on the poster I have which is the actual size of the machine. Maybe if it was a thinner (lower tog) duvet it would've fitted.

oh right, I am just thinking maybe LG is not true to size. I am sure I read on there website the LG can handle Kingsize duvets of up to 11.5 tog. Maybe thats the 11Kg Model though!! Yes, sorry meant 78l.

Post# 608031 , Reply# 60 7/3/2012 at 16:54 (322 days old) by dyson2drums (United Kingdom)
I think thats for the 11kg and 12kg models which have a 78l drum. Mines 69l, still pretty big :) The dyson could handle duvets upto 13.5 tog as far as I remember.

*Blog* Ah right I get what you mean, internet spam? Hi Fido Good questions, and a tough one! My answers are based on giving mine enough time to establish that the repair would actually be viable for any normal type of usage. Time will tell! A) I may contemplate it, if people were willing to send the drum unit to me then I would access it to see if it may last or be too far gone (the spiders). B) I think really depends on the assessment of the drum assembly. Due to the size of the bearing and tightness, I don't have a decent size of extractor that would cut a lot of the time and effort out. However if there was demand then I would invest in one. It would probably be approx �85 in parts for the main bearing, main seal, and the inner bearings and seal.

D2D yes the instructions say * The Dyson washing machine will wash most machine washable king size duvets up to 13.5 tog. (note: different manufacturers duvet sizes can vary under the same tog rating) * If the duvet is over 10.5 tog, we do not recommend spinning it. If it is 10.5 tog or below, we recommend a maximum spin speed of 500rpm. Oh well I spun my summer duvet at 1400rpm so that tested the bearings a little lol. Shame the duvet wash did not go higher than 40c, would like a 60 on this.

I just managed to wash our 10 tog kingsize duvet in my Miele 6kg. When I say just, I washed it on delicate at 60deg ( high water level and 3 high rinses ) then ran it through extra rinses but kept having to open the door and re position before the spin. I would not try this again.

I used to wash all the duvets in the house when we had the dyson, they always went through a max spin cycle once the cycle had ended for quicker drying. Even in the LG, the duvets were put through a seperate spin at 1400 once the standard 1000rpm on the duvet cycle is done. Only the dyson CR02 allergy (silver model) had a 60 degrees duvet wash.
