All,

I've been doing some video scouring on YouTube to try and get an idea of what the Miele Spiders look like.

In February, I posted thread # 26920 with the same topic, but I never got a good idea of what they look like.

These photos below are some snips of what I was able to find both by a residential and professional Miele washer being rebuilt. Note that the residential has 3 arms, the professional 4.

Both of these machines are probably from the 80's - early 90's, but I'm sure Miele has kept the design pretty much the same.

Note how they are solid, not cast and semi-hollow.

Thoughts?

Andrew

Spin Speeds

Hi Guys.

Does anyone think that with modern washing machines of today with very fast spin speeds could be the cause why some are un-reliable.

I remember once reading in an old Which Magazine saying they compared 2 machines, one with 800rpm, and one with 1000rpm, and the drum mountings appeared to be unchanged, Which said looks like their could be a reliability problem with fast spin machines.

I know today modern machines have been designed to spin at high revs, but I wondered if the slower spin machines could be more reliable.

My Miele HomeCare is 1400rpm, but only use it on 800rpm, as I have a separate spin dryer.

I am just curious about this issue.

Cheers

Paul

Paul,

I commented some time ago that I felt that as spin speeds and capacity increased, there would be a corresponding increase in unreliability....

Spinning large loads (say 6kg+) at over 1200-1400rpm puts enormous stress on components that simply don't exist if you spin a smaller load at higher revs....

reliability

couldn't agree more. the size/spin race (led in my opinion in the Oz market by Samsung/LG) seems to have become more important than the longevity of the machines. give me a base model Miele everyday at 6.5kg and 1100rpm for 10+ years of service versus a 10kg 1600rpm that will crap itself in no time.

Remember reading over on a UK appliance site that yes, higher final spin speeds seems to equal shorter lifespan of washers.

Case in point might be the scores of older front loaders that maxed out at <1100 rpms, still giving daily service sometimes >twenty years of use.

High spin speed coupled with even slighly off balanced loads causes vibrations. This goes on often enough things are bound to shake loose and or cause stress damage.

While washing machine makers have gone to great lengths to get the public sold on high spin speeds equals better water extraction, thus less work for the dryer (which translates into energy savings), there is something of diminishing returns.

After about 1200rpms, the amount of extra water extracted is minimal. Surely not enough to warrant a huge increase in dryer time.

....I'm sure I've read that somewhere before actually....could have been in an ASKO/ASEA pamphlet years ago, but the amount of additional moisture removed by going beyond 1200rpm (say to 1600rpm) is only about 10% of what is left....not what you started with....

But as with soooo many things, consumers are led by bigger numbers...bigger capacity, higher spin speeds....etc

The details below come from my Miele dryer manual.
Up to 1600RPM there is benefit in higher spin speed, but it drops off after that.

Spin KWH Time
1200 rpm 2.65 kWh 86 mins
1400 rpm 2.55 kWh 82 mins
1600 rpm 2.25 kWh 74 mins
1800 rpm 2.20 kWh 73 mins
This is based on a cottons normal drying program. So about .5kWh from 1200-1800RPM

The standardised EU tests seem to have covered 800rpm and 1000rpm when my dryer was made and they show the following. Unfortunately the standards didnt go high enough.

Spin
800 rpm 70% Residual
1000 rpm 50% Residual

I still think quality has to do with it, my Miele's have the following spin speeds and ages
W423 - 33yo - 1100RPM
W2515 - 7yo - 1400RPM
W2888 - 5yo - 1800RPM

None of them are showing any sign of wear and just keep on doing what they do. As Chris mentioned above, their advantage is the smaller drum diameter. The RPM's might be the same accross all 1400RPM machines, but a full size US machine has a much higher drum surface speed than a Euro machine with a 50-60L drum.

Spin Speeds

Hi Guys.

Chris, I only use my Miele HomeCare washer on about 800rpm, I think the machine will last longer by doing this. I do have a separate spin dryer that spins at 2800rpm, so my clothes are so dry when they have been spun in my separate spin dryer.

Also, when I want to use my dryer, they don,t take as long to dry.

I remember my mum having a Hotpoint Microprofile that had a 1400rpm, the machine would only spin on 1400rpm for a few seconds.

Thanks for advice

Paul

My 19 year old Miele spins at 1400rpm. I've always used the highest spin speed on it and it is still working flawlessly. The only repair I had on this machine were the shock aborbers, but these are getting the most wear during the start of a spin cycle, not at the highest spin speed.


I wouldn't hesitate to use the highest spin speed on a Miele. They really are made to spin at it's highest speed.

BTW, my Miele spins 3 minutes at 1400rpm

Wow

Hi Louis.

Wow, your Miele washer 19 years ols and still going strong even at the high spin speed.

I have no idea how old my Miele washer is. My fiend recently bought a house and the people who he bought the house from emigrated to New Zealand.

They left quite a number of electrical items in the house, one off which was a Miele HomeCare washer. My friend asked me if I wanted the washer, I of course said YES PLEASE, lol.

Its a great machine and so quiet even on spin. I sold my Bosch Maxx 5 washer, as I was not impressed with it.

Miele Washer

Hi there.

I checked on the Miele website, but my model not on there. Its in very good condition, but as you say, its only about 3-4 years old.

Great machine though.

Paul

You can contact Miele to ask how old your machine is. Miele in the Netherlands helped me out with my vintage Miele toploader.

1000 series

It is a 1000 series washer, which has only been around for a few years. It has a polycarbonate door rather than metal and a flat fascia panel. Also no removable lid so when stacking with a dryer is a bit taller than the traditional models.

Spider corrosion

To vacfanatic,
Thank you for posting the photographs of the various spiders. I find them quite informative.
Please would you mind answering a few easy questions?
1. On post 465688 (the first one). Do you have any idea what the white substance showing in the centre of the spider is?
2. On post 465689. Same as question 1. but in addition do you have any idea what the grey marking outside the white substance is?
3. On post 465691. Could you tell me what machine this spider is from/for? To me it looks like a disaster waiting to happen!
4. Post 465692 unfortunately looks like a Frigidaire built machine also sold under the Kenmore and GE names.
5. On post 465693. That looks like one from a Whirlpool Duet also sold as Kenmore HE, could you please confirm or otherwise.
Thank you very much for your time.
I look forward to your response with anticipation.

Andrew the drum you pictured appears to have a cast spider, that type of part would have to be cast of what I can't tell by the picture but most likely some type of aluminum.
