Does anyone have any pics of their machines causing damage to themselves?

Heres apic of my machine which marks its glass doors on unbalanced spins. On one spin the machine jumped up a bit AND THIS MACHINE IS SUPPOSED TO HAVE OUT OF BALANCE CONTROL!! LOL

This is a design fault. Regardless as to whether the machine has out of balance control or not, the design should stop the drum from touching the glass.

It's a pity if one thinks that in the last millennium A.E.G. dropdown Lavamats had flat windows mounted on the outer tub. No rubber boot ---> no rubber (..and glass) wear.

In household machines today this system is used only on classic ASKO, but is still common on commercial units

In the pic the last one on sale here in Italy (1983). In the same catalogue there were newer Lavamats as the likes of Steve 1-18 and Eddy's ones

Thats pretty bad, even by modern ELectrolux Group standards!

Our old Electrolux Premier (dated from around 2000), which ran identically to a Zanussi Jetsystem Excel model, used to leap about like it was possessed, but it never damaged the glass, possibly because the glass didn't reach as far into the drum as on your AEG. It would often move a good foot out of position though, even when washing relatively light weight loads. We had Service Force out within the first few months as we couldnt believe it was normal. They fitted a new motor for some reason (can't remember why) but claimed the leaping about was normal.

The noises it'd make would have you think it was near death, but it soldiered on for 7 years until the motor packed up and took the PCB with it.

The Zanussi Essential we have now is much better by comparison, though it too occasionally jumps more than you'd think it should. Over the weekend it went abit wild and turned itself round so the front faced a 5 o'clock position (6 o'clock being normal) but this is the first time ive seen this in 22 months ownership. The suspension does seem very soft though, and the drum often moves around loads, albeit without the machine itself shifting.

Would AEG not be at all interested in hearing about your machine? Im guessing not from what ive heard about Electrolux Customer Care, but surely something is buggered on your machine to allow it to do what is happening?

Best of luck anyway,
Liam.

I think theres gotta be something wrong with it. My mums AEG 74640 does many out of balance spins is on tiled flooring and hardly moves! Same with my Zanussi zwf12070G1! Its not moved anywhere since i installed it! It too is on tiled flooring!

I think maybe one of the suspension legs is to fault!

I've been nothing but pleased with all my electrolux products!

Well....

...I had both suspension legs replaced yesterday on the Zanussi/Westinghouse....it wasn't jumping around at all, just making a dreadfull 'tunk tunk tunk' noise when spinning...

But, for AUD$245 it at least sounds like new again...

Well...

 I had an AEG that scored the door glass. That machine had a tendency to shift about in its space too, as it vibrated quite a bit on spin. The AEG was in a flat that had conventional wooden floorboards.

The Zanussi IZ was very stable (in the same flat) and never moved an inch.

The Zanussi was also stable in the current flat that has those modern chipboard floor panels. But the Panasonic is even steadier.

AEG OKO LAVAMAT 72640

 There's no fault with the machine - it has done this from day one. We have had service force out to look at the machine because when we used to wash towelled robes in the machine you can guarantee the machine will be crashing on start up on one of its spins. The Service Force engineer was instructed to strip the machine as we had stressed our concern for a machine of this price doing this and with it being AEG, we expected it to behave better than the 'cheaper' machine we have had before. This machine cost us �400 in 2002 which is a fair bit, obviously not as much as Miele. The engineer could not find a fault with the machine.

If one looks at the machine, you will see there is a design fault with the way the glass is quite low, close to the drum and rubber lip so when there is a major inbalance the drum is able to make contact with the glass door. Our Older Indesit never really used to have that much movement with the drum but say if the drum ever shakes,the way the glass was positioned, the drum could not make contact with it. The Indesit seemed to have better out of balance control than the AEG. The AEG senses there is an inbalance, tries to balance the load and the machine tries and tries, then it decides to just spin anyway and theres a loud crashing sound at the start and slowing down on the spin cycles. I guess if the machine was more 'sensitive' with balancing, it will never do a Spin Rinse which it spins 3 times with water when its rinsing to remove detergent.

The way the out of balance works on this machine is that the machine has a set predetermined speed in which the drum has to achieve, the speed seems to be monitored by the microprocessor - the information is fed from the tacho. If the load is not balanced then this will affect the speed so the module knows and then tries to balance. What appers to be going wrong in the AEG is that it notices thers an inbalance and tries to rectify it but then it either gives up and spins anyway or the microprocessor does pick up the fact that the load is not balanced as the drums speed has picked up quick enough for the machine not to notice its not balanced.

Apart from this I have to say that the machine is very good and reliable even though it does this from time to time.

I have heard of other AEG's having this problem and I am very surprised that this has not been picked up by the company. I have not written anything to Electrolux AEG Germany but I did notify the customer service team in the UK. Working in customer service myself, I doubt they will be very bothered if no one else has reported this with their machines.

Showing the machine washing then starting its first spin burst. You will notice the machine try to balance, its not balanced, then it tries again and its no better than before but the machine continues into a spin anyway, luckily it was only a spin burst. The machine does this after the main wash as the water is sudsy until the full speed is achieved so this is not a out of balance cut out feature as this machine doesnt seem to have that. This part is at the end of the vid

Oh goodness! It would be interesting to see what stiffer shock absorbers would do. My AEG started to act like this when the shock absorbers were gone, it could be that they used shock absorbers on this series that are not stiff enough.

After seeing the videos, it has the same washing & spinning routine as my Mums Electrolux Premier, which also leaped around on spin.

That too, did the whole fast slow fast slow fast routine when washing, and also did a very short burst of spin with tonnes of shacking around like the AEG. The Zanussi we have now has just one speed for the wash and will do 4 short distributions before spinning, unless it detects imbalance, in which case it'll spin the drum really slowly to attempt to balance, then try again. The spin bursts are never as short as on the AEG or our previous Electrolux either.

It kinda begs the question whether AEG actually tested this machine before letting it go out to shops, as either the suspension should be harder or the door glass should be a different shape. Electrolux Group machines are my favourite of the lot, but that wouldve gone back to them in 2002 if it were mine. The jumping about is one thing, but the drum making contact with the glass just shouldnt happen. Imagine if it broke the glass while you were out of the house and then attempted to fill with water - bye bye kitchen!



Post# 377806 , Reply# 12   9/9/2009 at 16:40 (5,335 days old) by fl1012 ()        

Also just thought, if the Zanussi keeps detecting an imbalance, it'll stop and begin the distribution (clockwise, anti-clockwise, clockwise, anti-clockwise) again, to see if it has success second time round.

It uses a system called FUCS (i had to check the spelling) - stands for Fast Imbalance Control System. Not sure if this is a modification of the system your AEG uses, or a totally new one. The way it behaves is similar, but with a few bits tacked on, which seems to produce quite decent improvements over the AEG (from 2002) and our Electrolux (from 2000). The Zanussi is a 2007 Essential model by the way (ZWF 14170W).

Mine too!

 My washing machine´s glass door is marked too and obviously it has the same door as AEG03´s machine has as well.
But mine actually isn´t that unbalanced on normal cycles as it will gash the door. One time, I had an enginner from AEG Germany at my place as the shock absorbers were making a cracking noise when it was washing a load above the temperature of 60°C. He started a load and he let the machine wash for quite some time. But as he was in hurry, the machine didn´t reach a temperature above 60° and so he started a spin cycle in the service test mode. As in the service test mode, the out of balance control is turned off, the machine started ramping up it´s spin speed heavily unbalanced. The result was that ugly crack in the door glass.
Furthermore, I have to say that the shock absorbers weren´t replaced and the cracking noise also disappeared within some time. But I also have to mention that AEG´s customer service is really bad!

But I´m still pleased with that machine as it washes very well using little water and also because it´s reliable.
The only thing what worries me is that ugly noise that it´s making from time to time (--> follow the link to youtube!)

Variomatic. Hi, Have you managed to get a look into what thr shock absorbers look like? I suspect they are better then the ones I have as I think the AEG's 1400RPM and over has the 'thicker' type like the Zanussi's. Mine only have very basic 'stick' things as the spin is max 1200RPM.

Post# 377930 , Reply# 16   9/10/2009 at 14:04 (5,334 days old) by variomatic ()        

I already did look at them as they need some drops of oil from time to time. Actually they look the same but when I have some time left, I will look at them again and take a photo.
Today I´ve been washing a load of towels and the machine spun the load at 1800 rpm even though it was very unbalanced. My dryer is installed on top of my washing machine and the items laying on the dryer all dropped down on the floor - fortunately, it has been some boxes of dryer sheets :)

FL1012 I agree totally with you. What if the machine had smashed the glass and then start to fill with water, goodness knows what would have happened. Luckily I dont think too much as this machine has such low water levels, the water doesnt reach high enough to flood the kitchen but I dont like it when others in the house decide to put the machine on in the middle of the night as this machine has tripped the electrics on 2 occasions and there was smoke in the kitchen - I thinbk this was caused by the major vibrations in the machine, it caused a connection to come out at the top making the machine stop working and trip the electrics, we put it back in and the machine was ok. We purchased a Zanussi with a Jetsystem as we love having the jet in the machine but when the AEG was ok again we cancelled the purchase. One thing is when this machine has finally had its day I will miss the spin rinses as it seems they dont do them on the newer ones anymore.

Variomatic. Our machine doesn't vibrate, just the drum shakes very bad, the machine is so stable even when spinning on 1200RPM on an unbalanced load, I have a video on Youtube where the machine was shaking a bit, this was because the machine had jumped slightly to the left on the most unbalanced spin ever and dislodged its feet position in the lino so the machine shaked a little. Shame the AEG's are not like what they were just a few years ago.

my hotpoint did this to the glass door as well, took me ages to figure out what it was, i thought it was damage from the rubber seal. it happened not long after i bought it as well (2005) pft so much for all these new machines doing spin balancing acts whats the point!

Rinse Hold, which model was this? I think the most effective out of balance is the older Bosch Fuzzy Logic Spin system.

Wow that's really bad

 Obviously the suspensions have too much "give" in them, allowing the drum to move so much that it can hit the glass.

It shouldn't matter how out of balance the machine spins, it should be impossible for the drum to hit the glass, the suspension shouldn't stretch far enough for that to be able to happen.

I have noticed the AEG and Hotpoints mentioned that do this seem to have very "loose" suspensions which allow a much greater amount of movement than most machines.

I do hope they are aware of this and have sorted it in the current models.

Matt

I saw a repair book and the engineer was repairing a Hotpoint Ultima - the newer generation. It has exactly the same inferior type of suspension leg.
